Various feeder layers have been extensively applied to support the prolonged growth of human pluripotent stem cells (hPSCs) for in vitro cultures. Among them, mouse embryonic fibroblast (MEF) and mouse fibroblast cell line (SNL) are most commonly used feeder cells for hPSCs culture. However, these feeder layers from animal usually cause immunogenic contaminations, which compromises the potentia...
The death domain kinase RIP has an important role in DNA damage-induced, p53-independent cell death.
Tumor suppressor p53 plays a critical role in cellular responses, such as cell cycle arrest and apoptosis following DNA damage. DNA damage-induced cell death can be mediated by a p53-dependent or p53-independent pathway. Although p53-mediated apoptosis has been well documented, little is known about the signaling components of p53-independent cell death. Here we report that the death domain kin...
The interferon-induced, double-stranded RNA-dependent protein kinase (PKR) can play critical roles in inhibiting virus replication and inducing apoptosis. To develop new agents that may inhibit viral replication or induce apoptosis in cancer cells via the PKR signaling pathway, we screened a chemical library for compounds that have differential cytotoxic effects on wild-type [mouse embryonic fi...
Objective(s):To culture thein vitro mouse embryonic stem cells (mESCs) and to direct their differentiation to germ-line cells; in present study we used a vector backbone containing the fusion construct Stra8-EGFP to select differentiated ES cells that entered meiosis. Retinoic acid was used to differentiate embryonic stem cells to germ cells. Materials and Methods: A fragment of Stra8 gene pr...
A 6.7-kilobase met complementary DNA (cDNA) was isolated from a pcD cDNA library prepared from C3H mouse fibroblast cell line polyadenylated RNA. Sequence analysis of 6.7-kilobase met cDNA insert revealed that it contained the entire open reading frame and shared an overall homology of 88.1% with the human met gene. Using the mouse met cDNA as probe, high levels of met expression were observed ...
introduction: embryonic stem (es) cells are pluripotent cells derived from the inner cell mass of blastocysts. these cells are appropriate for creation of animal models of human genetic diseases, the study of gene functions in vivo and differentiation into specific types as potential therapeutic agents for several diseases. we describe here production of transgenic chimeric mouse blastocysts by...
How do we study the endocrine cell differentiation of the placenta? The accepted course of action dictates that you use primary trophoblast cell cultures derived from human placentas. This is accomplished using methods to isolate cytotrophoblasts that possess the potential to spontaneously differentiate into endocrinologically active syncytial trophoblast within a prescribed period of time (1)....
Despite progress in developing defined conditions for human embryonic stem cell (hESC) cultures, little is known about the cell-surface receptors that are activated under conditions supportive of hESC self-renewal. A simultaneous interrogation of 42 receptor tyrosine kinases (RTKs) in hESCs following stimulation with mouse embryonic fibroblast (MEF) conditioned medium (CM) revealed rapid and pr...
the aim of this study was to isolate mouse embryonic stem cells from late blastocyst stage embryos and to use them as a model system for the study of hematopoietic induction outside the embryo by coculturing of embryonic stem cells with bone marrow stromal cells. blastocyst stage embryos from pregnant nmri mice were obtained and cultured for 1-2 days in dmem medium. the inner cell masses formed...
