Increase of monoploid GS in polyploids in comparison to diploid progenitors is less well documented and probably less common (e.g., Hordeum, [ 22]; Nicotiana, [ 23]; Melampodium, [ 24]).
Notch signaling was more active in Sox2hi and AT1/AT2 progenitors and less active in terminally differentiated ciliated and AT1 cells (Fig. 2).
During cultivation, the CD45low fraction increased and the CD45high fraction decreased indicating that NA-BMCs contained more progenitors and less differentiated hematopoietic stem cell compared to regular bone marrow cells.
Testicular stem cells and progenitors represent less than 10% of the adult germ cells and are located along the basal membrane of the seminiferous tubule, which also includes meiotic and haploid cells.
Based on the distribution of Tbr2 expressing cells in the developing cortex, the observation that Tbr2 expression follows the known developmental gradient (rostral-lateral first to caudo-medial last) is consistent with the possibility that early VZ progenitors are less likely to generate intermediate progenitors and more likely to produce additional radial progenitors.
Second, lineage-restricted progenitors require less elaborate manipulation to derive more mature cell populations.
In addition, in a "two-way-pseudo-test-cross" mapping strategy, intercross markers i.e. markers with the same heterozygous allelic configuration in both progenitors, are less informative.
Third, the ability of an immigrant population to radiate adaptively has much to do with the properties of the colonists (and progenitors) and less with differences of habitat.
From differentiated cells, as saphenous vein-derived endothelial and fibroblast cells, to progenitors or less committed elements, as mesenchymal or endothelial progenitor cells, a strong propensity for adhesion and/or tissue integration has been demonstrated [ 6– 8].
It is noteworthy that in the presence of ICI, the colony-forming potential of the luminal progenitors was less than that of the cultures treated with ethanol as controls.
Hauswirth et al. reported that the ectonucleotide pyrophosphatase/phosphodiesterases 3 ectoenzyme (E-NPP3 = CD203c) is an activation-linked cell surface antigen that is expressed on blood basophils and their progenitors and less abundantly on normal MCs [ 77].
