More than just mice
As well as simply looking at the effects that the drugs had when administered to mice, scientists also checked to see whether the inhibiting effects on Janus kinase were similar when administered to human subjects.
Because the studies haven’t yet reached the stage of being tested on people, hair follicles from humans were grown in laboratory conditions and then grafted onto the mice.
When the drugs were given to the mice, the same effects were seen, with new hair growth appearing in the same way that it had previously.
One of the leads for the report, Dr Angela M Christiano, cautioned that it couldn’t yet be considered as a cure for baldness but said that the drugs were extremely promising.
She went on to say that the next stage would be for a formula to be developed for specific use on the scalp to see if hair growth could be repeated again.
