“Regarding your inquiry, the joint research project that was announced in July is still in early stages of research. The work with hair follicle regeneration is led by the Laboratory for Organ Regeneration, but this is still work carried out in animal models. The team must now try to make their approach suitable for uses in humans. This requires a tremendous amount of time and effort. Before any method is established as treatment, it must also go through clinical research trials or clinical trials to confirm safety and efficacy of the procedure, and to receive approval from the appropriate regulatory organizations. Research, unfortunately, does not always progress as fast or as easy as one hopes, and thus it is difficult to confidently say when and if this join research will reach the stage that it can be used in humans.
The process they are proposing to use is taking a few hair follicle samples from a patient, extracting and isolate mesenchymal stem cells and epithelial stem cells from the hair follicles, and using a method that the lab developed to culture these two cell types to generate many follicular primordium, which will be transplanted into the hair loss area, using methods similar to current hair transplantation methods, and the transplanted follicular primordium should generate hair shafts.
We hope this helps answer your questions.
