R&D PSC001 Irradiated Mouse Embryonic Fibroblasts (5 vials)
产品编号 PSC001| rndsystems
Irradiated Mouse Embryonic Fibroblasts (5 vials)
产品介绍
Kit Summary
For use as a feeder layer when culturing embryonic or induced pluripotent stem cells.
Ready to use
MEFs support undifferentiated growth of embryonic and induced pluripotent stem cells
Inactivated by gamma irradiation to avoid chemical contamination
Consistent feeder layer to reduce experimental variation
Free of microbial and mycoplasma contamination
The Importance of Mouse Embryonic Fibroblasts in Maintaining Undifferentiated Cells in Culture
Mitotically inactive mouse embryonic fibroblasts (MEFs) support the growth and maintenance of stem cell pluripotency by secreting necessary soluble factors and by providing a substrate for stem cell attachment. See Details
Components
Five vials of irradiated mouse embryonic fibroblasts are provided with 6 x 106 cells in each vial. See Details
Stability and Storage
Store in liquid nitrogen for up to 2 years.
Quality Control
R&D Systems iMEF are tested for their ability to support undifferentiated growth of BG01V human ES cells as assessed by Oct-4 and SSEA-4 expression. They are mycoplasma negative as tested by the MycoProbe™ Mycoplasma Detection Kit (Catalog # CUL001B) and negative for microbial contamination.
Precautions
This product contains 10% dimethylsulfoxide (DMSO).
Data Examples
Human Pluripotent Stem Cells Cultured on Mouse Embryonic Fibroblasts Express Pluripotent Markers SSEA-4, Oct-3/4, Oct-4A, and E-Cadherin. A. Human iPS2 stem cells were cultured on Irradiated Mouse Embryonic Fibroblasts (iMEF; Catalog # PSC001). Expression of SSEA-4 was detected using a Mouse Anti-Human/Mouse SSEA-4 Monoclonal Antibody (Catalog # MAB1435) followed by the NorthernLights™ (NL) 493-conjugated Donkey Anti-Mouse IgG Secondary Antibody (Catalog # NL009, green). Oct-3/4 expression was detected using a Goat Anti-Human Oct-3/4 Affinity Purified Polyclonal Antibody (Catalog # AF1759) followed by the NL557-conjugated Donkey Anti-Goat IgG (Catalog # NL001, red). The nuclei were counterstained with DAPI (blue). B. BG01V human embryonic stem cells were cultured on Irradiated Mouse Embryonic Fibroblasts (iMEF; Catalog # PSC001). Expression of Oct-4A was detected using a Mouse Anti-human Oct-4A Monoclonal Antibody (Catalog # MAB17591) followed by the NL493-conjugated Donkey Anti-mouse IgG Secondary Antibody (Catalog # NL009, green). Expression of E-Cadherin was detected using a Goat Anti-Human E-Cadherin Affinity Purified Polyclonal Antibody (Catalog # AF648) followed by the NL 557-conjugated Donkey Anti-Goat IgG (Catalog # NL001, red). Nuclei were counterstained with DAPI (blue). View our protocol for Fluorescent ICC Staining of Stem Cells on Coverslips.
BG01V Human Embryonic Stem Cells Cultured on Irradiated Mouse Embryonic Fibroblasts Demonstrate a Phenotype that is Consitent with Pluripotency. A. BG01V human embryonic stem cell colonies cultured on Irradiated Mouse Embryonic Fibroblasts (Catalog # PSC001) were analyzed for markers of pluripotency after 3 passages. B. Cells were evaluated for SSEA-4 expression by flow cytometry using a PE-conjugated Mouse Anti-Human SSEA-4 Monoclonal Antibody (Catalog # FAB1435P; filled histogram) or a PE-conjugated Mouse IgG3 Isotype Control Antibody (Catalog # IC007P; open histogram). C. & D. BG01V human embryonic stem cell colonies were incubated with a Goat Anti-Human Oct-3/4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1759) or a Goat Anti-Human Nanog Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1997). The cells were stained with the NorthernLights™ 557-conjugated Donkey Anti-Goat IgG Secondary Antibody (Catalog # NL001). Expression of SSEA-4, Oct-3/4, and Nanog is consistent with a pluripotent phenotype. View our protocol for Fluorescent ICC Staining of Stem Cells on Coverslips. |

Background: Embryonic Stem Cells
Embryonic stem (ES) cells are pluripotent stem cells derived from the inner cell mass of pre-implantation embryos. Induced pluripotent stem (iPS) cells can be generated by somatic cell reprogramming following the exogenous expression of specific transcription factors (Oct-3/4, KLF4, SOX2, and c-Myc). These cell types are capable of unlimited, undifferentiated proliferation in vitroand still maintain the capacity to differentiate into a wide variety of somatic cells. In this capacity, pluripotent stem cells have widespread clinical potential for the treatments of heart disease, diabetes, spinal cord injury, and a variety of neurodegenerative disorders.
R&D Systems offers a wide range of products to support pluripotent stem cell culture and differentiation. Mouse embryonic fibroblasts may be used to maintain and expand pluripotent stem cells in an undifferentiated state. We also offer defined culture media, which are specifically optimized for use with human or rodent pluripotent stem cells. In addition, R&D Systems offers a variety of products to assess differentiation status and identify specific stem cell types of interest, including panels of marker antibodies, primer pairs, multi-color flow cytometry kits, and specialized verification kits.
