| Telomeres, the "aging clock", start shortening immediately after birthWhile stem cells exhibit the capacity to differentiate and self- renew, their ability to do so is now known to decline with age. At the level of individual cells, replicative capacity is to reason that telomere dynamics should be intimately involved with this age-related decline in stem cell function. To this end, a recent study has investigated telomere dynamics in a longitudinal study of fetal and early post-natal subjects. |
