Stem cells, which have the potential to turn into any kind of cell, offer the tantalizing possibility of generating new tissues for organ replacements, stroke victims and patients of many … Continue Reading Researchers have discovered a new pathway in stem cell differentiation.
A protein that normally fosters tissue repair instead acts to inhibit healing when sugar levels are high, according to a study in The Journal of Cell Biology. The data findings … Continue Reading Researchers map epigenetic cause of slowed diabetic wound healing.
Human DNA accumulates damage over time, and older people’s bodies can’t repair it as well. Many scientists believe a build up of damage can cause cells to enter an irreversible … Continue Reading Study identifies molecular link between DNA damage and premature aging.
An injection of stem cells into the eye may soon slow or reverse the effects of early-stage age-related macular degeneration, according to new research from scientists at Cedars-Sinai. Currently, there … Continue Reading Stem cell injection reverses vision loss due to age-related macular degeneration in animal model.
Researchers at UC Davis have illuminated an important distinction between mice and humans, how human livers heal. The difference centres on a protein called PPARα, which activates liver regeneration. Normally, … Continue Reading Researchers find FGF21 boosts liver regenerative ability.
Scientists at the University of California, Berkeley, have identified a new molecular pathway critical to aging, and confirmed that the process can be manipulated to help make old blood like … Continue Reading Researchers identify new mitochondrial pathway critical to aging.
A research team at UC San Francisco has discovered an RNA molecule called Pnky that can be manipulated to increase the production of neurons from neural stem cells. The opensource … Continue Reading Researchers identify noncoding RNA crucial for stem cell suppression in the brain.
The heart tissue of mammals has limited capacity to regenerate after an injury such as a heart attack, in part due to the inability to reactivate a cardiac muscle cell … Continue Reading Researchers induce microRNA-based cardiomyocyte proliferation after heart attack in animal model.
A team of researchers from the University of Pittsburgh state that it might be possible to heal cirrhotic liver disease by rebooting the genes that control liver cell function. If … Continue Reading Rebooting cell programming via precision medicine reverses liver failure in animal model.
For infants with severe combined immunodeficiency (SCID), something as simple as a common cold or ear infection can be fatal. Born with an incomplete immune system, kids who have SCID, … Continue Reading Researchers grow and correct an SCID immune system in-a-dish via precision medicine.
Rice University scientists have developed a hydrogel that can be injected into an internal wound and help it heal while slowly degrading as it is replaced by natural tissue and … Continue Reading Researchers develop ‘injectable’ blood vessels.
In a study that provides scientists with a critical new understanding of stem cell development and its role in disease, UCLA researchers have established a first-of-its-kind methodology that defines the … Continue Reading Scientists develop method to define, standardise stages of stem cell reprogramming.
Sensory hair cell loss is the major cause of hearing loss and balance disorders. The postnatal mammalian inner ear harbors progenitor cells which have the potential for hair cell regeneration … Continue Reading Researchers regenerate inner ear hair cells via the Notch pathway to restore hearing.
A team of scientists, led by researchers at The Wistar Institute, has found that an infection with herpes simplex virus 1 (HSV-1) causes rearrangements in telomeres, small stretches of DNA … Continue Reading Researchers map previously unseen herpes-telomere interaction.
Columbia University Medical Center researchers have devised a way to replace the knee’s protective lining, called the meniscus, using a personalized 3D-printed implant, or scaffold, infused with human growth factors … Continue Reading Researchers develop regenerative medical approach with 3d printed meniscus.
A research group from the Cluster of Excellence at the TU Dresden (CRTD) demonstrated for the first time the in vitro growth of a piece of spinal cord in three … Continue Reading Spatially, anatomically correct spinal cord grown in the lab for the first time.
