Aging Muscle Fix? Blocking NDRG1 Makes Old Stem Cells Act Young Again – But There’s A Catch

Scientists at the University of California, Los Angeles, have identified a key reason why muscle repair slows with age. In older muscle stem cells, a protein called NDRG1 accumulates and acts as a brake on rapid regeneration, according to a study published in the journal Science. The finding reveals a biological trade-off: while NDRG1 slows […]
