It’s not just about implanting new hair, but deciphering the mechanisms of hair growth, to apply them to the hair itself.
Japanese researchers from Yokohama National University have managed to grow hair follicles or her in the lab. This milestone is considered the key for new baldness treatments and the White hair.
A hair follicle It is the sac-like structure where the hair is born. It is found in the epidermis, the outermost layer of the skin. Hair begins to grow at the bottom of the hair follicle, where the root is nourished by blood from nearby blood vessels, indicates Insparya.
As explained the press releasethe work of these researchers has focused on creating cultures of “organoids“, simple versions of an organ that serve to better understand the development of organs and tissues.
Researchers have found that when a hair is born, a series of “messages” between the epidermal layer of the skin and the mesenchyme or connective tissue of the skin. these characters stimulate the production of hair folliclesa process known as morphogenesis.
To create the cultures, they started from rodent embryonic cells because they are easier to obtain, the hair grows faster and it is more genetically manipulated.
Hair grown in the lab: the end of baldness?
The researchers were able to grow hair follicles manipulating those “messages” back and forth between the embryonic cells and the skin. They achieved an efficiency of almost 100% and achieved healthy and mature hairafter 23 days of cultivation.
“This technique helps us better understand how hairs are formed and what happens when certain external stimuli are applied in the process.explains Dr Junji Fukuda, in health line.
“We can also continuously observe how melanosomes enter the hair and become pigmented, which can help us understand the causes of gray hair and develop drugs to treat itYes.”
The consequences for baldness or gray hair are countless. dr. Fukuda has already revealed one: new treatments for remove or prevent gray hairs.
It also predicts that the treatments of hair regeneration will be more effective because “our method prepares hair follicles with hair shafts before transplantation, which can greatly improve the effectiveness of hair growth“, To explain.
In addition, by controlling the signals exchanged between the capillary embryo and the skin, treatments can be created that: regrowth of hair on the patient’s own skinor what remove gray hair.
East culture of hair follicles or hair in laboratorycould revolutionize the baldness treatments and the White hair. The ultimate cure is a little closer…
