Better Hair Transplants On The Horizon?

Engineering Better Hair Transplants -- Science News

Cell-based approach to new follicles takes hold in skin.

A hair-raising trick may lead to better hair transplants. Engineered hair follicles patched into skin can be coaxed to connect to surrounding tissue and to grow hair in an organized way, a study in mice finds.

Unlike current hair transplant methods, which simply move existing hair follicles from one area of the scalp to another to cover a bald region, the approach would spur the creation of new hair follicles from existing cells.

Genetics Rather Than Stress To Blame For Grey Hair

From The Telegraph:

Women who find themselves going grey should blame their parents rather than their stressful lifestyles, research has found.

Scientists studied more than 200 identical and non-identical twins between the ages of 59 and 81. They found that there was little difference between the greyness of identical twin sisters, implying that their varying lifestyles or upbringing had little impact.

Among non-identical siblings that did have differing levels of grey hair, 90 per cent of cases could be attributed to differing genetic factors, researchers from Unilever, who conducted the research published it in US journal PLoS ONE, found.

Stem Cells In Hair Follicles Point To General Model Of Organ Regeneration

Deep roots. For a hair follicle to begin a new phase of growth, an elusive group of cells called the hair germ (bright red) must be activated. This progression of images shows that the hair germ begins proliferating (green) before other cells do, suggesting a two-step mechanism. (Credit: Image courtesy of Rockefeller University)

From Science Daily:

ScienceDaily (Feb. 16, 2009) — Most people consider hair as a purely cosmetic part of their lives. To others, it may help uncover one of nature’s best-kept secrets: the body’s ability to regenerate organs. Now, new research from Rockefeller University gets to the root of the problem, revealing that a structure at the base of each strand of hair, the hair follicle, uses a two-step mechanism to activate its stem cells and order them to divide.

The mechanism provides insights into how repositories of stem cells may be organized in other body tissues for the purpose of supporting organ regeneration.
