Therefore, a major goal remains to understand the complex cellular and molecular network that controls HSC generation and expansion. In fact, HSCs that are mainly slow cycling (Wilson et al., 2008) and reside in the bone marrow during the entire life of an individual, are not generated there. They a

Introduction Human embryonic stem E64 (HESCs) can differentiate into the three embryonic germ layers and have the potential to develop into every cell in the human body (Thomson et al., 1998). In order to enable the clinical practice of HESC cell therapy it is essential to understand their differen

One BRCA2 (BRCA2 6174 delT) and two BRCA1 (BRCA1 5382insC and BRCA1 185 delAG) founder mutations account for 90% of inherited BRCA1/2 mutations in patients of Ashkenazi Jewish descent (Petrucelli et al., 2010). Because 0.1% of the Ashkenazi population carries the BRCA1 5382insC mutation, we estimate

In summary, we have dissected the specific role that OCT4 plays during the first steps of reprogramming independently of the other reprogramming factors. We have shown that OCT4 does not require SOX2 to interfere with cell-type-specific gene-expression profiles or to initiate an unstable transcripti

Discussion Generating neural stem urotensin ii from hESCs and iPSCs has been successfully achieved by a number of groups (Elkabetz et al., 2008; Falk et al., 2012; Koch et al., 2009; Nemati et al., 2011). However, the simplicity and retained – or even enhanced – differentiation versatility combi

2018-10-20

Why the maintenance factors are not essential for normal dhpg development is unclear. One possibility is that under normal conditions, the inner cell mass is transient, so that even the complete absence of any of these factors does not produce the full detrimental effect. However, if the inner cell

Introduction The vasculature is a multicellular system in which each cell type plays an important and indispensible role in its function. The inner lining of endothelial cells (ECs), which are in direct contact with the blood, is surrounded and supported by perivascular cells—either vascular smooth

Quiescent, long-term repopulating HSC (LT-HSC) are believed to reside predominantly in periendosteal areas of the BM characterized by low oxygen levels (Mohyeldin et al., 2010; Suda et al., 2011; Eliasson and Jönsson, 2010). Moreover, it is recently being suggested that HSC and hematopoietic progeni

The Bag1KO-mESC line maintains a classical dome-shaped ES cell morphology and expressed high levels of ES-associated protein such as, alkaline phosphatase (Fig. 1D). Immunofluorescent staining for the three key pluripotent stem cell markers Oct4, Sox2 and Nanog revealed that the Bag1KO-mESC line was

This study indicates that miR-124 and miR-219 may also be involved in the neurogenesis-to-gliogenesis switch by NSPCs. miR-124 promotes neurogenesis via downregulation of several genes (Sox9, Scp1, and Ezh2) that are positive regulators of gliogenesis or negative regulators of neurogenesis in the de
