Hair cloning, hair multiplication, the new hair loss treatment
Cloning is the action by which a gene is introduced into the cell and transmitted, replicated into the cells issued of this clone division.
This is how we create the cellular lines used for medical studies or when proteine are produced.
The most complete cloning consists in replacing completely the genes of an embryonal cell which nucleus was removed by the gens of an adult cell. By doing so, the cellular core recovers a new lease of life that will permit to reconstitute a full organism entirely similar to the organism which is coming from. Many animals where cloned with this method, Dolly the sheep, mouse, pig, horse...and some endangered species. It was not made on human people, yet.
Hair Cloning does not exist, the right expression should be the multiplication of the hair: tissue engineering or hair genetic engineering.
How does it work?
It is the same principle than the in vitro multiplication of the plants where a little piece of the plant is taken from the mother plant. This piece, cut in multiple fractions, will create multiple plants similar to the mother plant. This is how we reproduce roses, orchids, strawberry plant.
Since many years, artificial human skin is a reality.
For example, L'Oreal Group uses for its research an artificial skin composed of 3 types of cells.
The skin created is incomplete as it does not contain hairs or sweat glands.
Regarding hair, stem cells can be harvested on the external surface of the hair follicle. Contrarily to the differenced cells, which are able to subdivide themselves so to give similar cells, those cells are able to, when injected into mouse’s skin (or on the owner of them), subdivide themselves into different ones and to make an almost complete follicular entity.
In fact, the arrector pili muscle and the sebaceous glands are missing.
The leading experiences made by Aderans, an American company in Philadelphia, and Intercitex, Ambridge and Manchester (UK), consist in extracting two types of human follicular cells: the first ones on the bottom, the others on the side of the hair.
The jointly injections of these two types of cells permitted the production of complete human hair, in the skin of the mouse, previously hairless, or into the scalp of patients.
