چکیده

Satellite cells are myogenic stem cells responsible for the postnatal regeneration of skeletal muscle. Here we report the successful in vitro induction of Pax7-positive satellite-like cells from mouse embryonic stem (mES) cells. Embryoid bodies were generated from mES cells and cultured on Matrigel-coated dishes with Dulbecco's modified Eagle medium containing fetal bovine serum and horse serum. Pax7-positive satellite-like cells were enriched by fluorescence-activated cell sorting using a novel anti-satellite cell antibody, SM/C-2.6. SM/C-2.6-positive cells efficiently differentiate into skeletal muscle fibers both in vitro and in vivo. Furthermore, the cells demonstrate satellite cell characteristics such as extensive self-renewal capacity in subsequent muscle injury model, long-term engraftment up to 24 wk, and the ability to be secondarily transplanted with remarkably high engraftment efficiency compared to myoblast transplantation. This is the first report of transplantable, functional satellite-like cells derived from mES cells and will provide a foundation for new therapies for degenerative muscle disorders.

Evaluation and Comparison of the Expression Levels of the ZBTB16 (Plzf) and ZFP Genes and Alkaline Phosphatase in Three Cell Populations: Mouse Spermatogonial Stem Cells, Embryonic Stem-Like Cells (Es-Like), And Embryonic Stem Cells

Introduction: One of the vital enzymes during spermatogenesis, which is one of the pluripotency factors of stem cells and contributes to maintaining their pluripotency is alkaline phosphatase. ZBTB16 and ZFP proteins are critical elements in stem cells which are expressed in pluripotent stem cells and maintain their pluripotency due to their role in messaging pathways.

CFU-GM Like Colonies Derived from Embryonic Stem Cells Cultured on the Bone Marrow Stromal Cells

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...

The effect of Fibroblast Growth Factor-2(FGF-2) and retinoic acid on differentiation of mouse embryonic stem cells into neural cells

Introduction: Embryonic Stem (ES) cells as pluripotent cells derived from the inner cell mass of blastula can differentiate to neural cells in vitro and this property is valuable in studies of neurogenesis and in the generation of donor cells for transplantation. In this regard, the propose of this research, was the study of the role of two important factors in the development of neural syst...
