What’s more important than Woolly Mammoth de-extinction research in the stem cell arena? Only maybe a 10,000 other things.
Still, the mammoth de-extinction efforts capture people’s attention much more than the average research story.
Mammoth De-extinction update
Is de-extinction only a pipette dream? This startup has a big, expensive plan to find out, Popular Science. I’ve written before about George Church’s project to bring back Woolly Mammoths.
I still think it’s a lousy plan even if it’s fun to think about in a bubble but not in the real world. In reality, there are many ugly outcomes possible.
It might be a moot point because the way things are going so slowly, there’s a solid chance this particular de-extinction will never happen. George and I might need to be de-extincted ourselves by the time a real Woolly Mammoth could be brought back.
The firm Colossal Biosciences keeps ‘watering down’ the creature it might create to the point it wouldn’t be a Mammoth. No tusks. limited Mammoth DNA, etc. Probably more like an odd, maybe sickly hybrid elephant. Bad idea.

Hundreds of stem cell clinics sell the types of orthobiologics tested in this rigorous trial. However, the trial found no benefit over standard of care: “In summary, this study shows that at 1 year post injection, there was no superior orthobiologic as compared to CSI for knee osteoarthritis.”

Still, this is cool research. It was led by stem cell and developmental biologist Teruhiko Wakayama.
