Researchers say their findings could lead to new methods of care for bone injuries and might even give rise to clinical limb regeneration. (via FieldandStream)
published on February 24, 2023, the results could one day be adapted to heal bone injuries and regrow lost limbs.
The Xi’an researchers started by investigating the cellular make-up and gene expression dynamics of antler tissue throughout various stages of growth. Once they’d isolated stem cell populations with the most potency and potential for regenerative effects, they started inserting those cells directly into the heads of their test mice.that were no more than 5 days old.
It’s not the first time that Chinese scientists have grown something akin to a deer antler on the noggin of a mouse. In a similar study published in thein August 2020, researchers surgically removed antler tissue from living deer then used something called a cryogenic freezer mill to process the antler material before inserting it into nude mice. That study produced similar results with the mice sprouting visible, antler-like protrusions atop their heads.
The researchers behind the more recent study say that their work extends the catalog of mammalian stem cell systems that are known to science. With these newly-identified stem cell types, they’re hoping to expand the capacity of modern medicine. “Our results suggest that deer have an application in clinical bone repair,” the authors wrote in the study’s conclusion.
