Our observations on the behavior of the daughter cells arising from divisions of Tis21-nucGFP positive, i.e. neurogenic, BPs sTis21-nucGFP positivealmost all of these divisions (96%) are symmetric, i.e. geneurogenicghters with similar BPsavior and fate.
The remaining 81% are presumed to arise from division of existing corticotrophs (10% of the corticotrophs dividing once would be sufficient) and/or differentiation of SOX9−ve committed progenitors.
The woody tissue of trees is composed of xylem cells that arise from divisions of stem cells within the cambial meristem.
BPs arise from divisions of polarized APs and concomitant with, or following, the translocation of their cell body to the basal VZ or SVZ retract their apical process prior to mitosis [11].
Wood is composed of xylem cells that arise from divisions of stem cells that reside within the vascular meristem, known as the cambium or procambium.
In our study, Tbr2 is expressed only in the intermediate progenitors of the SVZ (Englund et al., 2005) that arise from divisions of Emx2+ progenitors (Haubensak et al., 2004; Miyata et al., 2004; Noctor et al., 2004).
Daughter cells arising from cell division behind the tip of the plant root or shoot may undergo great increases in volume.
Immature neurons arising from cell division express GAP 43 and doublecortin; they differentiate to fully mature neurons expressing OMP (Olfactory Marker Protein) [24] and olfactory receptors at the tip of their dendrite, when establishing synapses with the apical dendrite of mitral/tufted cells in the OB.
This cell renewal process has been postulated to arise from cell pressure arising from cell division in the basal layer [ 17].
First, each S. pombe cell has one old end, which was inherited from the dividing mother cell, and one new end arising from cell division.
