Regeneration

Thrombospondin-1 is a component of the senescence-associated secretory phenotype (SASP) produced by senescent cells. It has been shown in the past to induce blood-brain barrier dysfunction, but here researchers show that it also degrades mitochondrial function in macrophages, biasing those cells into the inflammatory M1 state. This in turn contributes to chronic inflammation and dysfunctional bone regeneration. The accumulation of senescent cells with age is known to be an important aspect of degenerative aging, and the SASP is known to change bystander cell behavior for the worse. There are likely countless mechanisms of this nature taking place in the aging body, all of which could be suppressed via reduction of the burden of senescent cells. The aging bone marrow microenvironment is characterized by chronic low-grade […]

Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off. Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring bone, joints, ligaments, and tendons after amputation in animal studies.

A team of Israeli scientists at the Hebrew University of Jerusalem has developed a novel method to significantly lower the production costs of cultivated meat. The new study demonstrates that preloading plant-derived cellulose scaffolds with growth factors supports the cost-efficient proliferation and differentiation of bovine stem cells. By binding these vital proteins directly to an anisotropic, directionally frozen framework instead of dispersing them in liquid media, this method achieves high-quality tissue development using up to 10 times fewer expensive factors. Upon multi-week cultivation and subsequent pan-frying, the cell-bound constructs show partially similar mechanical and visual responses to traditional sirloin cuts.

As climate change intensifies, one of the key challenges facing forestry is how to balance efficient timber production with the preservation of forests' climate-regulating functions, biodiversity, and resilience. The growing public demand for recreation in forests, together with increasing opposition to clear-cutting, is also driving the search for more sustainable management approaches.

Researchers here report an surprising, interesting, but not immediately useful discovery relating to the interaction of the immune system with wound healing in aged skin. Regeneration in aged skin is impaired, and non-healing wounds are one consequence of this impairment. The researchers found that priming aged skin with a dose of lipopolysaccharide, a toxic bacterial product that the immune system reacts to, improves skin regeneration after later injury. In the real world injuries are hard to predict ahead of time, so a better understanding how the observed changes in immune cell behavior provoked by this intervention are regulated is required in order to develop a form of therapy that usefully recreates the effects. Tissue repair is often hampered during aging. Worldwide, chronic wounds in elderly […]

One of the major projects within the study of comparative biology is the attempt to understand why adult individuals of some species can fully regenerate lost tissues following injury, while mammals such as our own species cannot. A variety of modest inroads into identifying potentially important differences in cellular biochemistry and activity have been made, such as work focused on senescent cells and macrophages, but it remains an unsolved challenge. Researchers here present more data to add to that already under consideration, focused on the role of oxygen sensing in the initial response to injury. It is unclear as to whether it can lead to dramatic improvements in mammalian regeneration, but the work suggests that regeneration could be improved via manipulation of oxygen sensing in […]

Efforts to identify and evaluate next-generation therapeutics for pediatric brain tumors are easily stymied by the quality and availability of laboratory models for research. To address this issue, scientists at St. Jude Children's Research Hospital developed patient-derived tumor organoids and tumor organoid xenografts that accurately reflect the biologic underpinnings of embryonal brain tumors.

Researchers here describe a novel approach to encourage greater regeneration in heart tissue following the injury and lost function incurred during a heart attack. Their work falls into the growing category of practical gene therapies in which a small amount of easily accessible tissue, such as fat or muscle, is transfected to form a factory that generates and releases a beneficial circulating protein. Only a low dose of gene therapy vector is needed, and all of the present challenges in broader delivery of gene therapy are bypassed. The scope of possible uses is restricted to situations in which benefits can be derived from increased amounts of a specific protein in circulation, but this is still a large enough set of possibilities to support a broad […]

Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why.

Oxygen and hyaluronic acid may play a role in tissue recovery and regeneration, two new studies suggest

Cartilage tissue exhibits a relatively poor capacity for regeneration even in youth, but this capacity for maintenance and repair diminishes with age. There are thus some gains to be made in understanding why this happens and developing means of rejuvenation, but ultimately some form of regenerative medicine above and beyond natural degrees of healing will be needed in order to completely address the very prevalent joint issues that occur in later life and culminate in disabling degrees of cartilage loss and osteoarthritis. While this is widely studied, cartilage has so far proven to be a difficult tissue for the tissue engineering community to reproduce and manipulate. The load-bearing capacity and resilience necessary for its function in the body requires an accurate recreation of the complex […]

Some animals can regrow lost body parts. Salamanders and frog tadpoles can rebuild entire limbs after amputation. Mammals cannot. For decades, biologists have tried to understand why. Now a team led by Can Aztekin at EPFL (now at the Friedrich Miescher Laboratory of the Max Planck Society) has discovered that oxygen plays a crucial role in limb regeneration. By comparing amputated limbs from frog tadpoles and embryonic mice, the researchers found that the way cells sense oxygen determines whether regeneration can even begin. The study is published in Science.

Sustainability has become something of a buzzword over the years. From the clothes we wear and the energy that powers our homes to the way we live our lives, the idea of sustainable production and consumption has become commonplace.

The capacity for neurons to regrow the axons that connect them is relatively limited. The tissue of large nerves, largely made up of axons, does not readily regenerate; the closer to the central nervous system one comes, the less the capacity for regrowth following injury. This is not the case for all species, and thus - in principle at least - there must be regulatory controls in cellular biochemistry that can be adjusted to encourage lesser degrees of obstructive scarring and greater regrowth of axons. Here, researchers report on one recently discovered way to enhance axon regrowth that works in both peripheral nerves and the spinal cord. Axon regeneration is limited in the mammalian central nervous system. Neurons must balance stress responses with regenerative demands […]

Cell cultures—single layers of cells grown in a small dish—have enabled researchers to study biological growth, develop or test drugs and even discover what causes some diseases. Cell spheroids, 3D versions of cell cultures built using a process known as cell aggregation, are the next step in advancing this work, capable of more closely modeling real tissue. A new technology, invented by researchers from Penn State and detailed in a paper published in Advanced Science, could breathe fresh air into bottom-up tissue fabrication and potentially large-scale tissue engineering by addressing these issues.

In a preclinical animal study, implantation of lab-grown esophageal grafts restored swallowing, offering hope for infants with long-gap esophageal atresia.

Experiments conducted in Brazil using laboratory rats have shown that graphene-based structures can act as a powerful ally in bone regeneration. These structures are made of sheets of the chemical element carbon that are just one atom thick. They can help heal fractures or bone loss. In the tests, the biocompatible matrix containing graphene facilitated nearly 90% repair of the damage sustained by the test subjects one month after the fracture was induced in the laboratory—a superior performance to that of other materials used in the research.

In chemical processes for producing pharmaceuticals, catalysts are a core technology that determines production speed and cost. However, until now, there has been a trade-off between "precise but disposable catalysts" and "reusable catalysts." A KAIST research team has developed an eco-friendly catalytic technology that combines these two types, operating solely with light and air. This opens a pathway to producing pharmaceutical ingredients more cheaply and cleanly, with expected reductions in carbon emissions and environmental pollution. The study is published in the Journal of the American Chemical Society.

Animal studies often fail to predict human tissue responses to new drugs or newly developed therapies. Besides generating tremendous costs for clinical studies, it also raises significant ethical concerns. Therefore, novel approaches to mimicking natural human environments like vascular system growth control, are broadly developed to deliver a reproducible model to test novel drugs.

A new Tasmanian Institute of Agriculture (TIA) study has found that while regenerative agriculture practices can improve soil health and reduce emissions on sheep farms, farmers often face trade-offs between environmental and economic goals. The article, "Regenerative agriculture improves productivity and profitability while reducing greenhouse gas emissions on Australian sheep farms," has been published in Nature Food.

Species capable of exceptional regeneration also tend to have longer life spans and slowed aging relative to similar species with less proficient regenerative capabilities. Various closely related species of spiny mouse have been studied in the context of mammalian regeneration because of their ability to shed a large amount of skin and supporting tissues as a defensive mechanism, and later regrow that tissue without scarring. This exceptional regenerative capacity extends to at least some internal organs as well. Spiny mice have been used in past studies that pointed to differences in the activity of macrophage cells as one of the important determinants of complete regeneration versus scar formation. Macrophages are innate immune cells that are deeply involved in ongoing tissue maintenance and regeneration from injury. […]

Technologies that convert carbon dioxide (CO₂) emitted from factories and power plants into useful chemical feedstocks are considered key to achieving carbon neutrality. However, rapid degradation of catalyst performance has long hindered commercialization. KAIST researchers have now developed a "self-regenerating" catalyst that restores its activity during operation, offering a potential solution to this challenge.

Some of the organs in the body do not have to be in their current location, nor structured in a single mass of tissue, in order to carry out all of their functions. The liver is one of these organs. Many (not all, but many) of the functions of the liver could be carried out by small amounts of liver tissue distributed throughout the body. Thus the existence of companies like Lygenesis, shepherding clinical trials of liver tissue organoid transplantation into lymph nodes to help restore lost function. Here, researchers report on the early stages of development for an alternative approach that is even less like normal liver tissue, essentially just an injection of cells and hydrogel rather than any production of structured tissue for […]

Loss of specialized cells is a feature of aging, exhibited in tissues throughout the body. There are many examples of cell types that could in principle be replaced once lost, but in practice are not replaced. The underlying reasons for this selective lack of regenerative capacity are incompletely understood. Examples of highly specialized cell types that do not regenerate include sensory hair cells in the inner ear and the podocyte cells of the kidney that are the subject of today's research materials. Interestingly, some of the cell types that regenerate poorly or not at all in mammals are in fact restored when lost in other species. While comparative biology allows for an exploration of these differences, cells are enormously complex and expanding the understanding of […]

APOE is a component of the low density lipoprotein (LDL) particles that carry cholesterol from the liver to where it is needed in the body. Lowering circulating LDL-cholesterol levels to modestly slow the progression of atherosclerosis is the primary approach taken in cardiovascular medicine; in recent years, new forms of LDL-lowering therapy such as PCSK9 inhibitors have been used to dramatically reduce LDL-cholesterol to far below normal levels with no immediately apparent prohibitively negative effects on patients. In today's open access paper, researchers show that elevated APOE levels are a feature of old age and negatively affect bone regeneration, likely by suppressing the creation of osteoblast cells responsible for producing bone extracellular matrix structures. A near complete elimination of APOE production in the liver (which […]

Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast moving “dancing molecules,” nerve fibers began growing again and scar tissue shrank. The results suggest the therapy could eventually help repair spinal cord damage.

Humans develop sharp vision during early fetal development thanks to an interplay between a vitamin A derivative and thyroid hormones in the retina, Johns Hopkins University scientists have found. The findings could upend decades of conventional understanding of how the eye grows light-sensing cells and could inform new research into treatments for macular degeneration, glaucoma, and other age-related vision disorders. Details of the study, which used lab-grown retinal tissue, are published today in Proceedings of the National Academy of Sciences.

A University of Missouri researcher is pioneering an innovative solution to remove tiny bits of plastic pollution from our water. Mizzou's Susie Dai recently applied a revolutionary strain of algae toward capturing and removing harmful microplastics from polluted water. Driven by a mission to improve the world for both wildlife and humans, Dai also aims to repurpose the collected microplastics into safe, bioplastic products such as composite plastic films.

Relative to skin elsewhere on the body, facial skin is less prone to scarring following regeneration from injury. Researchers have identified how this difference is regulated, and here demonstrate that they can influence the relevant mechanisms in order to reduce scarring during regeneration of skin injuries elsewhere on the body. It is also possible that further investigation of this biochemistry may yield approaches to reduce scarring more generally. This is of interest in the context of aging, as tissue maintenance becomes dysfunctional in many organs in ways that lead to excessive formation of disruptive small-scale scar-like structures. Surgeons have known for decades that facial wounds heal with less scarring than injuries on other parts of the body. This phenomenon makes evolutionary sense: Rapid healing of […]

Researchers at the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have found that a key protein can help to regenerate neural stem cells, which may improve aging-associated decline in neuronal production of an aging brain.

The thymus is a small inner organ near the heart that is responsible for the maturation of T cells of the adaptive immune system. The supply of new T cells is critical to the maintenance of effective immune function over time. Unfortunately the thymus atrophies over the course of adult life, and in most people is largely made up of inactive fat tissue by as early as 50 years of age. The resulting diminished supply of replacement cells ensures that the T cell population thereafter becomes ever more made up of malfunctioning, exhausted, and senescent cells incapable of mounting an effective response. Given the pressing need for ways to restore lost immune function in older individuals, it is good to see that a fair number […]

As we age, we don't recover from injury or illness like we did when we were young. But new research from UCSF has found gene regulators—proteins that turn genes on and off—that could restore the aging body's ability to self-repair.

Plants have an extraordinary ability to sense tissue damage and quickly rebuild their protective outer layers, a process vital for survival amid environmental stresses. The periderm—a specialized protective tissue found in many woody plants—serves as a crucial barrier against water loss, pathogens, and mechanical injury. However, understanding how gaseous molecules enable plants to rapidly detect surface disruptions has long remained elusive.

Like a phoenix rising from the ashes, our skin tissue—and in fact many types of epithelial tissue that lines and covers the body's organs—can respond to death and destruction with a burst of regeneration. This phenomenon, known as compensatory proliferation, was first described in the 1970s in fly larvae, which regrew fully functional wings after their epithelial tissue had been severely damaged by high-dose radiation. Since then, this surprising ability has been documented in many species, including humans, yet its molecular basis has remained unclear.
