Joy Kong compares adult and neonatal mesenchymal stem cells. Adult MSCs accumulate cellular damage over a lifetime, leading to cell death and senescence, while umbilical cord MSCs from newborns are young tissue largely spared from aging factors.
Our MSCs are a lot older than what's in umbilical cord. So does age matter? The fact that these MSCs are in US our entire lifetime makes them very susceptible to accumulation of cellular damages. So the longer we live, the more we accumulate these damages. So that can lead to cell deaths, senescence, loss of functions, or even cancerous changes. But neonatal MSCs. So these are very young birth tissue. It's a part of the umbilical cord, and they're spared pro aging factors.
