Aging muscle stem cells hoard NDRG1 to survive—slowing repair by 40% but doubling their lifespan. Remove it, and they fix muscle faster… then die off. Survival over speed, wired into their biology. 🧬 https://s.fitbodyscience.com/dzg6bc
Correlational — new studies may shift this
Links are real but observational — association, not proof of cause.
Older muscle stem cells play the long game—surviving longer but healing slower.
While the post claims this came from a UCLA study in Science, that specific study wasn’t linked. Other research found that in aging muscle stem cells, too much NDRG1 does make them live longer—but at the cost of being slower to repair damaged muscle. When scientists removed NDRG1, the cells got better at fixing tissue, but they didn’t survive as well. It’s like the cells chose to stick around, even if it meant being less helpful in the short term.
Sometimes, the best survivors aren’t the fastest workers—and that’s exactly what’s happening in aging muscle.
