"Deer Stem Cells Used to Grow Mini Antlers on Mice"

Scientists have successfully grown "mini-antlers" on mice by implanting deer genes into their genome, offering insights into how mammals can regenerate cells. Antlers are one of the fastest regenerating tissues in the animal kingdom, and the study provides a new look into how mammals can regenerate tissue, both by mechanisms within our genomes and with a little help from antler stem cells. The research could be utilized in human bone medicine, but cross-species implantation of cells raises ethical concerns and significant safety trials would be required before it could be submitted for approval.
