According to "Daily Mail" reported recently, the University of Kanazawa, Japan Research have discovered that hair follicle and human DNA, as would be "external pressure" damage. When the pressure is too large, the hair follicle melanocyte differentiation into stem cells will die, beautiful black hair will lose its presence.

led the study, Professor Kiyohiko Nishimura said: "The cells of the DNA will be affected by external conditions of the attack and destruction, such as mutations induced by chemicals, UV and radiation and so on. mammalian cells in vivo of a single encountered every day about 100,000 times the events of DNA damage. If the stem cell division gene damage arising in the course," A class = blue href = "http://www.mybased.com" target = _blank> color Su-manufacturing functions will be affected, resulting in the generation of white hair. "

However, another member of the study, Harvard University dermatology , director of the Department pointed out that David Fisher, the generation of white hair is a physical mechanism for self-protection. Olgensis hair shows that melanoma stem cells to generate the gene have been damaged and was removed. If these are destroyed the stem cells had not been cleared, they would be crazy to form the cancer cells reproduce. In other words, the same pressure, the white hair are more difficult to be suffering from cancer. Professor Dai Wei also said that the conclusions of this study is not limited to this, other features of the stem cell group's "death" or "premature differentiation" may be in helping the body resist cancer. Kiyohiko Nishimura said, the study challenges the previous "cell suicide", "the organ at all times we try to shake off gene mutation in the cells." She said.
