I am concerned about the characteristics issue. I’ve posted questions about whether or not the hairs would be long like head hair or short like arm hair, have the right angle, color, etc. Roger_that has stated that nobody knows yet and he’s right. Also, Bernstein said that there is evidence that the characteristics would be similar to the recipient area. Allograft cells need to be tested to find out the answers.
Even if it turns out that allograft produced hairs express the characteristics of the donor rather than the recipient there might be a way to make that switch.
