Why is Cell Differentiation the Major Obstacle for Hair Cloning?

Q: What is the major obstacle to hair cloning?

A: Although many problems remain, the main one is to keep cloned cells differentiated (the ability to perform a specialized function, like producing a hair). There are certain cells in the skin, called fibroblasts, which reside around the base of the hair follicle. These cells are readily multiplied in a Petri dish. When these cells are injected into the skin, they have the ability to induce a hair to form (they are differentiated). The problem is that when these cells are multiplied in culture, they tend to lose this ability (they become undifferentiated).

How Does Hair Cloning Grow Hair Follicles from Cultured Cells?

Q: Considering cell cultivation is made possible how could their injection create a normal formation of hair on the scalp and can they induce hair growth also in scarred areas where previously hair stopped growing?

A: That is the question. It is not known if these induced follicles will resemble normal hairs, and be cosmetically acceptable on their own, or if they will grow unruly and must be used as a filler behind more aesthetically pleasing transplanted hair.

What are Obstacles to Hair Cloning Techniques?

A: The main problem is that the cultured cells may lose their phenotype with multiple passages, i.e. lose their ability to differentiate into hair follicles after they have been multiplied.

Another problem of hair cloning is that the orientation of hair direction must be controlled. With mouse experiments, the hairs grow at all different directions. Scientists need to find a way to align the hair so that it grows in the right direction. Hair, of course, must also be of a quality that is cosmetically acceptable and matches the patient existing hair. And the hair should grow in follicular units. Individual hairs will not give the fullness or natural look of follicular units.
