"Neural stem cells puzzle" missing piece: telomerase reverse transcriptase expression patterns during nervous system ontogenesis in rats.

For almost three decades, neural stem cells remain still up-to-date and enigmatic topic. The main problem for their studying is the non-existence of an exclusive neural stem cell marker and the heterogeneity of them across the nervous system. As one of the novel markers of neural stem/progenitor cells may serve telomerase reverse transcriptase (TERT), a catalytic subunit of the telomerase enzyme, responsible for retaining the cell immortality.
