  Materials and methods Results Discussion The role played by Nurr1 in the regulation of NPCs across several acetylcholine chloride regions has been extensively investigated. It has been suggested that Nurr1 may exert a strong control on both the proliferation and differentiation of NPCs int

  2018-10-20

  

  In our reprogramming culture, aside from insulin production, we also observed expression of α and δ cell hormones, glucagon and somatostatin, respectively in a sub-population of cells. This is likely due to the constitutive expression of reprogramming factors Ngn3 and Pax6. Both transcription factor

  Acknowledgments Introduction Expression of a defined set of transcription factors (OCT4, SOX2, KLF4, and c-MYC) reprograms human somatic cells to a pluripotent state, generating induced pluripotent stem cells (iPSCs) (Park et al., 2008b; Takahashi et al., 2007; Yu et al., 2007). iPSCs are simi

  2018-10-20

  

  Single-cell expression profiling has allowed researchers to test the idea that gene expression variability reflects true biological variation in cellular mRNA levels. For example, in an analysis of individual pancreatic islet cells, the transcripts of insulin genes Ins1 and Ins2 were highly correlat

  The concept of neoblast specialization at wounds is important in understanding planarian regeneration and opens many avenues for future inquiry. For example, how is the neoblast response tailored to the identity of missing tissues? Do specialized neoblasts amplify their population, or do specialized

  2018-10-20

  

  MaSC numbers must be tightly regulated through a balance of self-renewal, differentiation, and senescence to prevent tumorigenesis, while accommodating high levels of cell proliferation during pregnancy. Several secreted factors such as WNT and Hedgehog promote self-renewal, but little is known abou

  Results Discussion These data identify a transmembrane molecule that negatively regulates AKT signaling via modulation of mTORC2 (Figure 4E). It joins the small number of mTORC2 upstream interactors, such as ribosome components (Zinzalla et al., 2011). Its transmembrane, putative cell-surface

  Direct cell-reprogramming technology is based on the dominant action of cell-lineage transcription factors (TFs) in converting adult somatic cells into different cell types (Graf and Enver, 2009). This technique represents a promising avenue in the field of regenerative medicine, with the potential

  Despite the central role of Pdx1/PDX1 in orchestrating pancreatic morphogenesis in mice and humans, vanishingly little is known about its direct transcriptional targets. Here, we chose to address this deficit by developing an in vitro human embryonic stem cell (hESC) differentiation protocol that sp

  From previous studies we know that cells above the bulge that are Sca-1 and CD34 negative also possess stem cell properties and that these stem cells are not label retaining cells, but relatively active in p-selectin (Jensen et al., 2008). This suggests that LRCs primarily reflects a certain patter

  Embryonic stem cell protocols frequently employ irradiated MEFs as feeder cultures (Conner and fibroblast, 2001). We plated mouse embryonic stem (ES) methysergide either with or without feeders and compared ALP expression in both cultures using our multiplexed luminescence method. Higher levels of

  It has previously been reported that differentiation of hESCs without the embryonic body stage led to an increase in the capacity of hESCs to differentiate into osteogenic progenitor c75 (Karp et al., 2006). Consistent with these findings, our differentiation culture method resulted in cells with i
