Understanding Cellular Senescence in Aging 👌🤔

Maybe you've heard about a little bit. One is called cellular senescence, like senile. So our cells grow and constantly replace themselves. We're born with a germ line of cells. We become an embryo and turn into a little baby. And by the time we go from germ cell to baby, before that time, we're actually immortal. Those cells can grow forever. But once we get actual tissues now, those cells are mortal. They're going to die at some point. And the cells are turning over over and over again. And over time, they start accumulating damage, damaging the DNA. The damage DNA has to be mitigated somehow, or it would turn into, like, a tumor, for example. And so our body has, which is called senescence, other protective mechanisms as well. But senescence, where if the cell has damage to it, it goes into a state of senescence where it stops growing.
