2018-10-20

Traditionally, the effects of radiation on spermatogonia have been evaluated by morphological analyses. It is considered that the percentage of seminiferous tubule cross-sections that show type A spermatogonia 10 days after irradiation is representative of SSC survival (van der Meer et al., 1992). A

In our previous studies (Choi et al., 2012; Vodyanik et al., 2006, 2010), we identified distinct stages of hematoendothelial development following hPSC differentiation in coculture with OP9 (Figure 1). Plating hPSCs onto OP9 stromal mtor inhibitor induces the formation of primitive streak and mesod

We used two complementary methods, MO-based knockdown and cell transplantation, to generate zebrafish containing a spectrum of PGC numbers. Our findings revealed that a threshold number of PGCs is required for the stability of ovarian fate. Furthermore, no compensatory proliferation of germ Atglista

To address this need, we have developed a functional imaging approach for CSC identification. The stem cell phenotype in embryonic stem Quercetin dihydrate manufacturer (ESCs) is maintained by a central triad of master transcriptional regulators, OCT4, SOX2, and NANOG, which promote stemness by upr

Introduction The NOD.SCID Il2rγ (NSG) mouse strain dramatically improved investigators’ ability to study human hematopoietic stem cell (HSC) engraftment (Rongvaux et al., 2013; Shultz et al., 2005). The NSG strain combines a series of mutations that inhibit the host’s immune system by different mec

2018-10-20

Over the last few years, gene editing by homologous recombination (HR) has been widely used in human NSC59984 to avoid undesirable transgene insertion. HR efficacy is very limited in human cells, estimated at one HR event per 106 cells; however, the potential application of HR in human cells has be

2018-10-20

Although the FDA considers analogous cell product data an acceptable option for preclinical studies, it requires substantial similarity between analogous animal and human products (FDA, 2013). Due to the significant differences in the innate and adaptive immune system (Mestas and Hughes, 2004), hema
