Hair Loss? Researchers Re-Grow Hair In Mice, Offering Hope For Hair Loss

Mouse with hair

Researchers found a way to regenerate hair growth using stem cells.
Here is a step-by-step simplification of the process the researchers used:

1. They removed a strip of skin from the back of the head (where hair is still growing)

2. From the strip they extracted dermal papillae cells, which contain genetic instructions for growing new hair.

3. They grew copies of the dermal papillae cells in a three-dimensional tissue culture. (The tissue came from infant foreskins discarded after circumcisions, a fact that many news reports chose to highlight.)

4. During the cell culture process, they turned the dish to foster clumping of the cells.
Once the scientists had the newly grown skin tissue complete with human papilla cells, they grafted it onto mice. Five of the seven mice used in the experiment experienced hair growth that lasted at least six weeks. The hair was then tested and found to contain the DNA of the original human donor.
