The complexity of the vertebrate brain makes it difficult to conduct such an analysis at the resolution of single progenitors and single lineages.
While some species have little diversity among accessions and concur with the GBSSI and nitrate reductase results, such as S. agrimonifolium, S. colombianum, S. hjertingii, and S. moscopanum, the results give much better resolution of species-specific progenitors.
In particular, resolution of the different stem and progenitor cell biology described in the papers by Mullally and colleagues, and Li et al. will be key to determining how MPNs develop and to designing future therapies.
However, the lack of cellular resolution of progeny cell fate, vital for dissecting progenitor division patterns, and the imprecise spatiotemporal control of clonal labeling have so far precluded a definitive understanding of this complex and dynamic process.
Knockout studies have revealed key roles for these proteins in normal biology that include the survival of a number of progenitor cells including renal epithelial progenitors, melanocyte progenitors, fetal erythroid progenitors, neuronal cells, sperm cells and hematopoietic stem cells [59 63].
Our resolution of these three taxa supports A. hasseltii as the maternal progenitor of A. subreflexipinna.
However, inclusion of a larger number of additional perA genes, including those from putative progenitor Epichloë species, would be expected to improve the resolution of analysis and obtain a deeper understanding of Epichloë- Neotyphodium phylogenomics.
Our analyses based on plastid data and the resolution of D. corleyi as sister to D. aemula suggest that D. aemula is the maternal progenitor of D. corleyi.
The resolution of γ-H2AX foci occurred at a slower rate in hESCs compared to neural progenitors (NPs) and astrocytes perhaps reflective of more complex DSB repair in hESCs.
While Tpx2 might affect microtubule orientation, the resolution of our assay system could not distinguish differences of EB3 movements in the thin process of neural progenitors between TPX2 knocked-down cells and control cells.
