A new treatment that blocks an aging-related protein restored lost cartilage in old mice and helped prevent arthritis after knee injuries. Human cartilage samples showed similar signs of regeneration, raising hopes for a future drug that could repair joints instead of replacing them.
I thought the central problem was telemore degeneration, not anything to do with stem cells per se.
Happy to be corrected if wrong; I never worked anywhere near this category in my very long ago now pharma/biotech phase.
That is part of it, which is what I alluded to in the degeneration of the dna. The stem cell thing too though. Our bodies aren’t programmed to live beyond a certain point. We learned about this in a Nature of Disease course at University.
