Boldness No More!

Summary: Yale students have recently found a source that triggers hair growth that may be helpful to baldness. Researchers have found that stem cells within the fatty lair showed that molecular signals were necessary to spur up hair growth in mice. "If we can get these fat cells in the skin to talk to the dormant stem cells at the base of hair follicles, we might be able to get hair to grow again," said Valerie Horsley, assistant professor of molecular, cellular and developmental biology and senior author of the paper. Men that are bald still have stem cells in follicles but lose the ability to start back up and grow hair. When the hair dies the fat layer of skin shrinks. When the hair starts to grow the skin expands and this is called adipogenesis. They found a stem cell that involved the creation of new fat cells which are called adipose precursor cells and they are what helped the mice’s hair grow. These cells also contain PDGF (platelet derived growth factors) and that is what helps human hair grow. Researchers are trying to figure out any other things that may trigger hair growth but for now they are trying to see if what they did to the mice might do something for human hair.

Critique: This article was good because it lets people know that hopefully there will be some help for people that can’t grow hair or are.

Impact: If what these people have found out works then that would be great for people that need or want to grow hair. People won’t have to wear wigs anymore and don’t need to go wasting their money on what they may think help their hair grow.
