Mature Cells Revert Into Embryonic-like Stem Cells With Help From Physical Cues
2013-10-21 09:40:41

University of California - Berkeley Bioengineers at the University of California, Berkeley, have shown that physical cues can replace certain chemicals when nudging mature cells back to a pluripotent stage, capable of becoming any cell type in the body. The researchers grew fibroblasts cells taken from human skin and mouse ears on surfaces with parallel grooves measuring 10 micrometers wide and 3 micrometers high. After two weeks of culture in a special cocktail used to reprogram mature...

Biological Clock Body Parts Age Differently

Brett Smith for redOrbit.com - Your Universe Online According to a UCLA researcher’s newly developed way of measuring a person’s biological clock, a woman’s breasts age faster than the rest of her body. The novel method developed by Steve Horvath, a professor of human genetics and biostatistics at UCLA, was created by studying methylation, a naturally occurring genetic progression that chemically changes DNA. "To fight aging, we first need an objective way of measuring it....

The mechanical properties of cells are often an indicator of disease. Cancer cells are typically soft and squishy. When the malaria parasite is inside a red blood cell, for example, the cell is stiffer than normal. Sickle cells also vary in stiffness. Research into the stiffness of diseased cells is lacking, in part due to limits in technology. Researchers have developed a new technology to sort human cells according to their stiffness, which might one day help doctors identify certain...

New research has shown that the stomach naturally produces more stem cells than previously realized, likely for repair of injuries from infections, digestive fluids and the foods we eat. Stem cells can make multiple kinds of specialized cells, and scientists have been working for years to use that ability to repair injuries throughout the body. But causing specialized adult cells to revert to stem cells and work on repairs has been challenging. Scientists from Washington University...

Human skin must cope with UV radiation from the sun and other harmful environmental factors that fluctuate in a circadian manner. A study published by Cell Press on October 10th in the journal Cell Stem Cell has revealed that human skin stem cells deal with these cyclical threats by carrying out different functions depending on the time of day. By activating genes involved in UV protection during the day, these cells protect themselves against radiation-induced DNA damage. The findings could...

2 studies suggest infusion of these cells may contribute to organ regeneration in the future Damaged or diseased organs may someday be healed with an injection of blood vessel cells, eliminating the need for donated organs and transplants, according to scientists at Weill Cornell Medical College. In studies appearing in recent issues of Stem Cell Journal and Developmental Cell, the researchers show that endothelial cells -- the cells that make up the structure of blood vessels -- are...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
