Telomeres of neurons: Do they also become more short?

  1. Jun 24, 2011 #1
    Hello all! During mitosis the telomeres reduced. But neurons do not divide during postnatal period (neural stem cells are exclusion). So - does Hayflick limit exist for neurons?
    Thanks

    Sure... the Hayflick limit is just the number of times a cell will divide. Most terminally differentiated neuronal cells would simply have zero divisions.

    Also, note that telomere length is not the only factor determining the number of replications.
