"Messengers" smack of DESIGN, not Random Chance over eons of time....for how/why would hair appear/grow along a supposedly evolutionary chain of events in the first place?...Howbeit the hair of his head began to grow again after he was shaven. Judges 16:22
"SCUBE3 potently stimulates hair growth and may offer a therapeutic treatment for androgenetic alopecia.
Dermal papilla cells are specialized signal-making fibroblasts at the bottom of each hair follicle.
The production of activating molecules by the dermal papilla cells is critical for efficient hair growth in mice and humans.
In people with androgenetic alopecia, dermal papilla cells
malfunction, greatly reducing the normally abundant activating
molecules.
“At different times during the hair follicle life cycle, the very
same dermal papilla cells can send signals that either keep follicles
dormant or trigger new hair growth,” said Professor Maksim Plikus.
“We revealed that the SCUBE3 signaling molecule, which dermal papilla
cells produce naturally, is the messenger used to ‘tell’ the
neighboring hair stem cells to start dividing, which heralds the onset
of new hair growth.”
