Back in November last year, The Belgravia Centre blog carried a story about an exciting new potential hair loss treatment involving the use of stem cells. The treatment has already been successfully demonstrated using bald mice in the laboratory where they have gone on to grow new hair naturally.
The proposed treatment takes a small strip of skin from the back of a patient’s head and extracts epithelial cells from the tissue sample. These cells are then encouraged to grow and ‘clump’ together before being injected back into the patient’s scalp. The clump of implanted cells then grows into a new hair follicle capable of growing hair.
Researchers have run into a few problems with the technique however. Mice were originally chosen for test subjects because their papillae cells are tightly clustered in the skin, making it easier for the transplanted epithelial stem cells to ‘communicate’ with each other and the surrounding tissues.
Humans scalps on the other hand have much larger gaps between papillae cells (in microscopic terms) making it much harder, or even impossible, for the implanted stem cells to perform their transformative work. Even if the treatment does work, the regrowth results are likely to be less impressive than those observed in the test mice.
The proposed treatment also has another problem it only deals with epithelial cells. Human hair loss involves two types of skin cells epithelial cells and dermal papillae cells. So even if stem cells can be used to kick-start regeneration of the epithelial cells, dermal papillae cells will be unaffected, meaning that hair regrowth is far from guaranteed.
Although this particular stem cell treatment has suffered a set-back, the findings are still being used to inform research into other potential hair loss treatments. As such, men and women affected by hair loss will need to rely on other proven medical treatments until researchers can identify another viable cure.
