MUSE cells migrate to damaged tissue, engulf dying cells, and absorb their DNA fragments. These genetic signals instruct the MUSE cells to transform into whatever cell type they just consumed, effectively replacing the damaged tissue with new, functional cells.
One of the cool things they do is that once they're in the damaged tissue, they actually can digest and eat up the damaged cells. But guess what happens when they eat up the cells? The DNA fragments from those cells that these different organ-specific cells actually can have different segments of the DNA that's turned on. And these DNA fragments actually trigger these mu cells to start manifesting and to actually become those cells that they just ate. So it's a very elegant way to replace the cells that are not good.
