Mouse to mouse worked, human to mouse did not. How well do you think human to human will do?
"When I arrive at Aderans, Dr. Washenik hastily ushers me past several labs, perhaps wary I might glimpse some sort of trade secret, and into an empty conference room. What he does reveal is that his approach to hair cloning (he calls it follicular neogenesis) doesn’t rely solely on dermal papillae. “We are using a two-cell construct, growing not just dermal papillae but also another type of cell from the follicle,” he explains. As the thinking goes, disparate cell types already communicate with one another in the follicle to regenerate hair. Dr. Washenik believes that if he can recreate that environment in the lab, cultured cells won’t get dementia and forget how to make hair. “The different cells in the follicle are smarter than we are,” says Dr. Washenik. “They already know they are supposed to be hairy. In eight days, we grew a ball of hair that never existed before on the back of a mouse.”
Dr. Washenik clicks an image file on his computer: The photo shows what looks like Piglet—but with a sable Mohawk. But there is a caveat: “These were hair cells from a mouse that were injected into a mouse. When researchers injected human cells into a mouse, they didn’t get the same results.” This disappointed Dr. Washenik and other researchers, because unlike other organs, follicles are supposed to be immune privileged: When transplanted across or between species, they’re expected to grow normally, without being rejected or provoking infection. He hopes to have better luck in clinical trials, when he will transplant human cells into humans. Aderans is in the second phase of a human trial, which is expected to be completed by the end of the year."
