Vitamin A plays an important role in skin wound healing
Whenever a small scratch occurs due to a fall, particular cells in
the skin are activated to heal the wound. New research tells us that this is
the stage where vitamin A plays a very important role.
According to media reports, a recent study conducted by American
researchers has shown that vitamin A instructs cells to 'repair' the skin after
an injury, as well as hair growth.
According to this research from Rockefeller University in New
York, these special cells are actually hair stem cells. But these usually don't
work until they determine whether to repair the skin or promote hair growth.
This recipe provides vitamin A.
As the skin is often injured, the hair cells are immediately
activated to compensate for the damage to the skin.
"With this new study, we now have a better understanding of
how to prevent various skin and hair disorders and cancer," said
Rockefeller University researcher Elaine Fuchs.
The researchers also discovered that adequate amounts of vitamin A
are essential for the efficient functioning of these cells. Too much vitamin A
can prevent cells from changing roles properly, while low levels can spend too
much time repairing the skin instead of growing hair. Note that when cells in
the body change their designated function, it is called lineage plasticity.
This process occurs in both cancer and wound healing.
