Scientists identify cells linked to graying hair & baldness

A team of researchers at UT Southwestern Medical Center claimed to have identified the cells that are directly responsible for giving rise to hair as well as the system that causes hair to turn gray.

Dr. Lu Le, Associate Prof. of Dermatology at UT Southwestern Medical Center’s Harold C. Simmons Comprehensive Cancer, revealed that they had started the project to understand how certain tumors form but they ended up identifying the cell that directly gives rise to hair and learning why hair turns gray.

When the researchers deleted the SCF gene in lab mice’s hair progenitor cells, the small creatures’ hair turned white. When they removed the KROX20-producing cells, the mice grew no hair and became bald.

The researchers expressed hope that their findings could one day help in the development of possible treatments for hair graying as well as balding.

Speaking on the topic, Dr. Le said, “With this knowledge, we hope in the future to create a topical compound or to safely deliver the necessary gene to hair follicles to correct these cosmetic problems.”

The encouraging findings of the new research published in the most recent edition of the journal Genes & Development.
