Do you know why the hair become white?

All over the world, human’s hair has six different natural colors. Some hair colors come when some people are born. Someone’s hair colour may change when they grow up. The hair color pigment hepatocyte is a important factor of hair color.  The reason why the hair become white?

A professor of Kyoto University recently discovered that the hair coloring pigment stem cells. And find the exact location of its existence through doing animal experiments. This help people to understand the reason why human hair turned white. the study of skin cancer caused by abnormal pigment cells make it possible to develop new drugs for preventing gray hair possible.

About a decade ago, Professor Nishikawa predicted the existence of a pigment stem cells, but can not prove. The experimental mice by altering the gene, Professor Nishikawa Et Al found that a pigment stem cell density in the middle of the hair root under the skin epidermis. With the changes in hair growth, pigment stem cells gradually move towards the the root.  and then access into pigment cells. Release melanin to make the hair colour changed. Sometimes it can move around the hair roots and play a role.

The findings, published in the latest issue of British “Nature” magazine. Osawa Peter Yi said, although human and mouse is different, it can understand the principle of white hair and the formation of stains. It is essential to study the deadly skin cancer melanoma caused.

Pigment stem cells, blood and neural stem cells receive widespread attention in the field of regenerative medicine. Professor Nishikawa said that using pigment stem cell research methods to identify the living conditions of stem cells, are a contribution to all stem cell research.
