The volumes were scaled down for 10 times, and the centrifugations steps were adjusted to 10,000?rcf. and differentiation of NSCs without changing their neurogenic potential. Strikingly, we recognized the choroid plexus of the mouse lateral ventricle as the major source of miR\204 that is released into the cerebrospinal fluid to control quantity of NSCs within the SEZ. Taken together, our results describe a novel mechanism to keep up adult somatic stem cells by a market\specific miRNA repressing activation and differentiation of stem cells. tenascin\c (Tnc) and thrombospondin 4 (Thbs4; Garcion mRNA and MEIS2 protein in acutely dissociated SEZ cells. Note that mRNA\positive LRCs have p85 low (no) MEIS2 protein. C, D IHC labeling for MEIS2 (C) and MCM6 (D) of LRCs positive for BrdU\only and neuroblasts noticeable by DCX. E Dot storyline showing the proportion of BrdU+ LRCs bad Pizotifen for MEIS2 or MCM6 protein. F Dot storyline depicting the manifestation of miR\204 in prospectively isolated cells of neural lineage.
