>Unfortunately, while these immature cells make cartilage that is youthfully regenerative during embryonic development or acute injury, they seemed to create cartilage that is dysfunctionally immature in the context of a chronic condition such as osteoarthritis.

>“When present on a longer term basis, hyperactivation of the immature program in cartilage cells is likely to promote inflammation and, ultimately, degeneration and fibrosis,” said Liu, a senior scientist in the Evseenko Lab.

That's a very big caveat that people should be aware of the research. This is extremely early and it is serving as a foundation for others to build work upon. You won't have this anytime soon (like 10 years + in a best case scenario).
