Dr. Joy Kong describes MUSE cells, which express pluripotency genes but carry zero tumor risk because they stop dividing once tissue is repaired. Unlike other stem cells, they thrive in inflamed environments, integrate into host tissue for months, and are immune-privileged, allowing transplantation without rejection.
These cells have zero tumor risk. Even though they are similar to embryonic stem cells, they don't have the same kind of tumorigenic potentials as embryonic stem cells, even though they express these pluripotency genes. But they naturally stop proliferation once the damaged tissue has been structurally repaired. So they know when to stop and not go haywire. If you do side-by-side comparison, they are able to survive better in inflamed tissue. The harsher the environment, the more effective they they're activated. And then there's advantage over umbilical cord and adult MSCs because they structurally can engraft into the host tissue and survive for months, offering a true structural reconstruction. Another beautiful thing about mu cells is that they are immune privileged. These mu cells express specific surface markers that shield them from the recipient's immune system, meaning that they can be mass produced and given to any patient without risk of rejection.
