The Growth Factor Environment Defines Distinct Pluripotent Ground States in Novel Blastocyst-Derived Stem Cells
Pluripotent stem cell lines can be derived from blastocyst embryos, which yield embryonic stem cell lines (ES cells), as well as the postimplantation epiblast, which gives rise to epiblast stem cell lines (EpiSCs). Remarkably, ES cells and EpiSCs display profound differences in the combination of growth factors that maintain their pluripotent state. Molecular and functional differences between ...
متن کاملP-126: Stem Cell Factor Increases Blastocyst Formation in Mouse Two-Cell Embryo Culture
Background: It is demonstrated that c-Kit( receptor of stem cell factor) mRNA is expressed in late 2-cell stage to the expanded and hatched blastocyst and the stem cell factor (SCF) transcript is detected in the oviduct and uterus. The aim of this study was to investigate the effect of different doses of SCF on mouse 2-cell embryo development in vitro. Materials and Methods: 4-6 weeks old femal...
متن کاملGermline Stem Cell Activity Is Sustained by SALL4-Dependent Silencing of Distinct Tumor Suppressor Genes
Sustained spermatogenesis in adult males and fertility recovery following germ cell depletion are dependent on undifferentiated spermatogonia. We previously demonstrated a key role for the transcription factor SALL4 in spermatogonial differentiation. However, whether SALL4 has broader roles within spermatogonia remains unclear despite its ability to co-regulate genes with PLZF, a transcription ...
متن کاملExpressional Analysis of Stem Cell Marker SALL4 in Mesencephalon during Chicken Embryogenesis
Background SALL gene family represent a group of evolutionary conserved zinc finger transcription factors which are involved in normal development. It includes four members (SALL1 to SALL4). SALL4 has significant roles in the maintenance of pluripotency and self-renewal, efficient proliferation /stabilization and cell fate decision of embryonic stem cells (ESCs). Our aim in this study was to a...
متن کاملDifferential roles of Sall4 isoforms in embryonic stem cell pluripotency.
Murine embryonic stem (ES) cells are defined by continuous self-renewal and pluripotency. A diverse repertoire of protein isoforms arising from alternative splicing is expressed in ES cells without defined biological roles. Sall4, a transcription factor essential for pluripotency, exists as two isoforms (Sall4a and Sall4b). Both isoforms can form homodimers and a heterodimer with each other, an...
