The first hair transplant procedure was carried out in 1939 — patients of dermatologists of that time were soldiers of the Second world war, suffered from severe burns. Since then, appeared at least two methods of transplantation of hair follicles from one body part to another, but the main problem of the technology has remained relevant — an operation could be carried out only to those people who have where to get hair. Now the situation has changed, because researchers from Columbia University for the first time in history managed to grow hair follicles in vitro.
New technology has great promise, and after commercialization can bring back the luxurious hair of millions of men and women from different parts of the world. The number of donor hair follicles will no longer play any role, because in the laboratory they now can be created in infinite quantities. What is more, the hair transplant procedure in the future might not be useful — having a large number of samples of human hair, manufacturers of remedies for baldness will be able to carry out more experiments and to develop more efficient products.
Scientists grow artificial hair follicles
The new technology of growing hair follicles consists of several parts. In the beginning researchers with a method of 3D printing has created the three-dimensional structure of biocompatible plastic material — it served as a vessel for the growth of hair follicles and recreated suitable for the growth of living cells microenvironment. Each channel with a diameter of 0.5 mm stimulated the formation of follicles, which subsequently were placed on cultured skin cells.
This kind of design was treated with the signal molecules, which suppressed the signaling pathway called JAK-STAT. From previous studies, scientists know that they hold the bulbs in a dormant state but due to the molecular treatment they aktiviziruyutsya and hair follicles begin to grow.
Researchers believe that by using technology they can create an entire farm to the hair follicles. The resulting grids with the hair can then be transplanted to the scalp, thereby returning people bald hair. The result of this operation you can see in the video below.
Sometimes for baldness save a very unexpected means. For example, in 2016 the researchers from Brazil found that a good choice of medication for treatment of rheumatoid arthritis.
