A molecular switch that seems to be essential for embryonic heart cells to grow into more mature, adult-like heart cells has been discovered by researchers at University of Washington. The … Continue Reading Researchers identify the molecular switch that promotes heart cell maturation.
Using proteomics techniques to study injured optic nerves, researchers at Boston Children’s Hospital have identified previously unrecognized proteins and pathways involved in nerve regeneration. The new study showed that adding … Continue Reading Researchers see an unprecedented degree of nerve regeneration using proteomics.
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.
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 Mount Sinai-led research team has discovered a new kind of stem cell that can become either a liver cell or a cell that lines liver blood vessels. The existence … Continue Reading Researchers discover new type of stem cell.
Investigators from the Université de Montréal have announced the discovery of a new molecule, named UM171, which allows for the multiplication of stem cells in a unit of cord blood. Umbilical … Continue Reading New molecule seen multiplying stem cells in a unit of cord blood in study.
Scientists have grown a fully functional organ from transplanted laboratory-created cells in a living animal for the first time. The researchers have created a thymus, an organ next to the … Continue Reading World’s first working organ grown in an animal from lab-created cells.
