TEXTO:
Stem cell therapy has been suggested as a
possible future treatment for hair loss for years.Although
various methods of generating skin tissue have already
been developed, their ability to imitate the real thing
[5] falls short.
A cure for baldness has moved a step closer after
skin was created in the lab, complete with hair follicles.
Using stem cells from mice, scientists grew both the
upper and lower layers, known as the epidermis and
[10] dermis respectively, for the first time. Professor Karl
Koehler, of Indiana University, originally began using
pluripotent stem cells — which can turn into any
organ — to create tiny versions of the inner ear, known
as ‘organoids’. But his team discovered they were
[15] generating skin cells in addition to inner ear tissue —
so they decided to try to coax them into sprouting hair
follicles.
The research published in Cell Reports found a
single skin ‘bud’ developed in culture can give rise to
[20] both the epidermis and dermis. This allows hair follicles
to form the same way as they would in a mouse’s body.
“The skin develops as a spherical cyst and then the
hair follicles grow outward in all directions — like
dandelion seeds,” said Professor Koehler.
[25] The new skin model more closely resembles
natural hair than any previous treatment. It could also
prove useful for testing drugs and reduce the practice
of animal testing as well as shedding fresh light on hair
growth.
