Scar free healing? University of Calgary researchers say reindeer could hold key to success | 24CA News
Reindeer might maintain the important thing to regenerative therapeutic in people and animals, says analysis led by the school of veterinary drugs on the University of Calgary.
The examine, printed earlier this month within the journal Cell, explains how reindeer — also referred to as caribou — might help to raised perceive tissue regeneration and suggests scar-free therapeutic might quickly be attainable.
It all began with a captive herd of about 25 reindeer on the veterinary faculty that’s used to show college students about wildlife drugs and to review the consequences of local weather change on weak species, akin to caribou.
Jeff Biernaskie, a professor of stem cell biology and regenerative drugs on the college, mentioned the annual regrowth of reindeer antlers additionally caught researchers’ consideration.
“Deer are the only mammal that are able to regenerate an entire organ as an adult so that, in itself, is really fascinating,” he mentioned in an interview. “The other thing is that it grows at such an enormous rate.”
Biernaskie, who has a PhD in neuroscience, mentioned he was blown away by how rapidly the antlers develop again.
“They are growing at a rate of one centimetre a day, which means that they are regenerating millions of cells … and assembling them into really intricate tissue in such a rapid fashion in order to build this antler over a period of three to four months,” he mentioned.
“A deer, like a caribou or reindeer, if they damage a branch of their antler, it will actually regenerate.”
Biernaskie’s interdisciplinary lab has a major curiosity in stem cell biology and tissue regeneration, together with the pores and skin.
“It got us thinking that maybe this would be a nice model to study skin regeneration,” he mentioned, including researchers puzzled whether or not the pores and skin on the antler — referred to as velvet — has the identical regenerative skill.
“Could we use that to learn something about how we might promote regeneration of skin following an injury in other animals or humans?”
They did study one thing.
Through a sequence of surgical experiments, researchers had been in a position to examine wounds on the antlers to these on the again pores and skin.
“In the back skin wound, we see formation of a fibrotic scar — this raised, non-pigmented scar that is very typical of what you might see in humans,” he mentioned. “In the velvet, it heals without any scar.
“This was really a breakthrough moment in that we now had a model that in the same animal where we could now compare the molecular and cellular processes that underlie the regeneration of skin in one setting and then the scar formation in another.”
Biernaskie mentioned researchers discovered a cell kind, the fibroblast, that’s very totally different between the 2 websites.
The final aim, he mentioned, can be to make use of what they’ve realized to develop therapies to advertise pores and skin regeneration in people — or different animals — with a extreme damage.
“We’re trying to modify that wound environment but also the injury response,” he mentioned, noting that would restrict the severity of a scar and even totally promote regeneration of the pores and skin.
Biernaskie, who’s the Calgary Firefighters Burn Treatment Society chair in pores and skin regeneration and wound therapeutic, mentioned it might assist sufferers with extreme pores and skin accidents resulting from trauma or surgical interventions.
“The burn survivor is where we would really like to apply this knowledge,” he mentioned.
Biernaskie mentioned it’s a groundbreaking development within the discipline of tissue regeneration that he hopes will assist to provide you with new methods to deal with sufferers.
