A breakthrough technique that can generate human hair growth shows promise for treating baldness in men and women, a new study suggests.
“If it works in humans, it actually opens up the possibility of hair restoration for many more patients than are currently available,” study co-leader Angela Christiano, a dermatology professor at Columbia University Medical Center, told NBC News.
In the study, Christiano and colleagues took dermal papillae — cells inside the base of human hair follicles — from seven donors and cloned the cells in tissue culture. After a few days, the cells were transplanted onto human skin that had been grafted onto the backs of mice.
The transplants resulted in new hair growth lasting at least six weeks in five of the seven tests, according to the findings. DNA analysis confirmed that the new hair follicles genetically matched the human donors.
The research is in its early stages, so it may be years before this science makes its way to the marketplace to help men and women with notable hair loss by age 60.
The study was published Monday in the online edition of the Proceedings
of the National Academy of Sciences.
I don't see how this would benefit people with alopecia. Unless I misunderstood my doctors, alopecia is caused by the immunity system attacking hair and preventing it from growing. Seem like a cure needs to be aimed at the immunity system. What is it I don't understand?
As she explains in the following video, Dr. Angela Christiano's current line of research was motivated by her own bout with alopecia areata and she and her colleagues "plan to stop at nothing until they have the disease figured out."
Here is another video in which Dr. Christiano discusses what she hopes to be implications of research for people living with alopecia areata:
Androgenic alopecia is not about something being wrong with your immunity system... It's about your genetically predisposed hair folicules being vulnerable to a certain kind of hormones. If you get a transplant of hair folicules from a donor who has healthy hair, these folicules are not going to be destroyed by your hormones. So it's genetic. Not your immunity system. But when it comes to alopecia areata, then yes i think it's your immunity system so i don't think that this discovery would be very helpful.
That's how I felt when I saw this. I wasn't sure how this research has anything to do with Alopecia as an auto immune disease, so I'm not sure why she mentions her own struggles with AA. Just to relate? It obviously wouldn't cure her if it came back again, she does have some bitchin' hair though.
I have Androgenic Alopecia as well. I guess what I took away from this is ..... it lasted 5 or 6 weeks..... that seems like a very short period of time, would hope for a longer period before claiming 'success'. However, ANY research is good. It means we are not being ignored.
More research my ass. I wont hold my breath. Find a cure for ignorance!
