WASHINGTON, April 4 (Xinhua) -- Liver stem cells that express high levels of telomerase, a protein often associated with resistance to aging, act in mice to regenerate the organ during normal cellular turnover or tissue damage, according to a study by researchers at the Stanford University Scho...
Human blood is designed to capture oxygen and safely bind it to a molecule known as hemoglobin. However, if you breathe in a high concentration of oxygen, it will overwhelm the blood, disrupting the central nervous system, damaging the lungs, heart and brain. How much oxygen do we inhale ...
Professor Norman Maitland, from the Department of Biology at the University of York, said: "The strong response we observed was due to the powerful cellular function called Notch. It was present in both normal and cancer cells and it's how a cell population can regenerate itself after radiothe...
Physicians and scientists at Cincinnati Children's Hospital Medical Center used new stem cell technology to regenerate and study living patient-specific skin in the lab, giving them a precise close up view of how inherited DNA defects cause skin damage a
Why do some cells have microvilli? What epithelial cell is best suited for diffusion? Are keratinocytes epithelial cells? How are microvilli formed in gut endothelial cells? Why do epithelial cells have many mitochondria? What type of epithelial cell often has cilia?
Hair is not living tissue that can regenerate – no nerves, no blood, no living cells.Products on the market promise to revive, restore and heal dry, damaged hair. But... there’s no way to actually heal damaged hair. Yes, high-quality oil, leave-in conditioner, and treatments can ...
Today, many expectant mothers are asked about umbilical cord banking -- the process of storing umbilical cord blood after giving birth. Why would someone want to do that? Once a mother gives birth, the umbilical cord and remaining blood are often discarded. However, this blood also contains st...
