EXCERPTS: Decades of textbook biology may need to be rewritten after an imaging study has revealed that hair does not grow by being pushed out from the root, as previously believed—but is pulled upward by coordinated moving cells.
The study by scientists from L'Oréal Research & Innovation and Queen Mary University of London, England, used advanced 3D live imaging to observe living human hair follicles in lab culture. The findings not only alter the basic mechanics of hair development but may open up new strategies in regenerative medicine and treatments for hair loss.
“Our results reveal a fascinating choreography inside the hair follicle," paper author and professor Inês Sequeira said in a statement. "For decades, it was assumed that hair was pushed out by the dividing cells in the hair bulb.
"We found that instead that it’s actively being pulled upwards by surrounding tissue acting almost like a tiny motor.” To test their theory, the scientists...
[...] The discovery could eventually help scientists develop new treatments for hair loss. By focusing on the pulling mechanism rather than just promoting cell division, future therapies might better support hair growth in people experiencing thinning or balding... (MORE - missing details)
