  After co-culture USSCs adjust their differentiation capacities to the stromal cell lines used in the experiments. The USSCs revealed HOX gene expression and an adipogenic differentiation potential. As an adaption to the CDSC type could be revealed in vitro, a molecular switching of osteogenesis vers

  In order to determine whether the neonatal mammalian heart harbors any significant regenerative capacity, we recently developed a surgical model of cardiac injury in 1-day-old neonatal mice (Fig. 1) (Porrello et al., 2011a). Following amputation of a portion of the ventricular apex comprising approx

  The first initiating event that starts the process of tumorigenesis must originate in a healthy cell. It is possible that this healthy cell may not be a stem cell (O\'Brien et al., 2007). However, given any cell of a healthy self-renewing tissue, the number of divisions that separates this cell from

  Material and methods Results Quiescent cells can be identified in vivo by virtue of their ability to retain label. Historically, this was achieved by treating animals with nucleotide analogues, for example 5-bromo-2′-deoxyuridine (BrdU) or tritiated thymidine, that are incorporated into DNA du

  Runx1 also controls the proliferation and neuronal differentiation of certain neural progenitor cell populations. In embryonic olfactory bulb progenitor cells in vivo, as well as in cultures of either embryonic olfactory progenitor cells or embryonic cortical NSPCs, Runx1 increases cell proliferatio

  Although the central nervous system is relatively immunotolerant (Barker and Billingham, 1977) and human fetus-derived NS/PCs and hESC-derived NS/PCs (hESC-NS/PCs) showed weak immunogenicity (Odeberg et al., 2005; Åkesson et al., 2009; Liu et al., 2013a), no studies to date have investigated the ext

  Unlike these previous methods, the 3S reprogramming system generates partially reprogrammed iPSCs in a reproducible and predictable manner by regulating the amount of KLF4. These apigenin resume reprogramming upon increased KLF4 expression and therefore are not aberrantly reprogrammed but have paus

  2018-10-20

  

  There are two major repair methods for DSB damage repair, namely HRR and nonhomologous end joining (NHEJ). HRR results in error-free repair, but NHEJ sometimes leads to errors. During HRR, DSB damage repair uses a template containing hundreds of harmine hydrochloride pairs of sequence homology, and

  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

  While the role of TAp53 (full-length p53) in CSC formation has been largely documented, the role of other p53 isoforms is still poorly described. The isoform Δ40p53, a highly expressed isoform in embryonic stem cells, has been proposed to control pluripotency by maintaining TAp53 in an inactive form

  It has furthermore been speculated whether Sca-1 plays a role in stem cell self-renewal. Thus, some experiments with Sca-1 −/− knock-out mice investigating hematopoietic and mesenchymal progenitor purchase A-366 have pointed to a role for Sca-1 in self-renewal (Bonyadi et al., 2003; Ito et al., 2003
