Human Pluripotent Stem Cell Functional Identification Kit Summary

Kit Summary

To verify pluripotency in human stem cells by in vitro functional differentiation.

Key Benefits

  • Verifies the pluripotency of your starting population
  • Only takes 5 days
  • Reduces experimental variation
 

 

Why functionally verify human stem cell pluripotency in vitro?

To determine if a cell is truly a pluripotent stem cell, it is important to verify its ability to differentiate into each of the three germ layers.

The teratoma assay is a standard way to assess pluripotency, but this method requires expensive animal models and is time-consuming, often requiring 6 to 10 weeks before pluripotency status can be determined. Similarly, embryoid body assays are time-consuming and rely on random differentiation.

  • Uses fully defined supplements to drive reproducible differentiation.
  • Provides results in 5 days to save time and reagents.
  • Avoids tissue embedding and sectioning procedures.
  • Can verify the ability to differentiate into 3 germ layers without the use of an animal model.
  • Verifies a healthy, pluripotent starting stem cell population to increase consistency between studies and reduce unwanted experimental variability.

 

Kit Contents

This kit contains the following specially formulated media supplements and growth factors to drive pluripotent stem cell differentiation and a marker to characterize each of the three germ layer cell types.

  • Differentiation Base Media Supplement (50X)
  • Ectoderm, Mesoderm, and Endoderm Differentiation Supplements
  • Ectoderm Marker: Goat Anti-Human Otx2 Antigen Affinity-purified Polyclonal Antibody
  • Mesoderm Marker: Goat Anti-Human Brachyury Antigen Affinity-purified Polyclonal AntibodyV
  • Endoderm Marker: Goat Anti-Human SOX17 Antigen Affinity-purified Polyclonal Antibody

The quantity of each component in this kit is sufficient to make 200 mL of media for differentiation. This is enough media for the differentiation of one 24-well plate of each cell type.

The acute and chronic effects of over-exposure to the reagents in this kit are unknown. Safe laboratory handling procedures should be followed and protective clothing should be worn when handling kit reagents.

Verification of Induced Pluripotent Stem Cell Pluripotency.
iPS2 human induced pluripotent stem cells were differentiated to ectoderm, mesoderm, and endoderm using the media supplements included in the Human Pluripotent Stem Cell Functional Identification Kit (Catalog # SC027). The kit also contains Goat Anti-Human Otx2 (ectoderm), Goat Anti-Human Brachyury (mesoderm), and Goat Anti-Human SOX17 (endoderm) Antigen Affinity-purified Polyclonal Antibodies for the confirmation of differentiation status. To further evaluate lineage commitment, cells were stained with a Goat Anti-Human SOX1 Antigen Affinity-purified Antibody (Catalog # AF3369), a Goat Anti-Human HAND1 Antigen Affinity-purified Antibody (Catalog # AF3168), and a Goat Anti-Human HNF-3 beta/FoxA2 Antigen Affinity-purified Antibody (Catalog # AF2400). The cells were stained using the NorthernLights 557-conjugated Donkey Anti-Goat IgG Secondary Antibody (Catalog # NL001; red) and the nuclei were counterstained with DAPI (blue).

JOY6 human induced pluripotent stem cells were differentiated to ectoderm, mesoderm, and endoderm using the Human Pluripotent Stem Cell Functional Identification Kit (R&D Systems, Catalog # SC027B). Differentiation was analyzed by flow cytometry using the protocol provided with this kit. Differentiated cells (orange) show increased expression of their respective lineage-specific markers (ectoderm - Otx2, mesoderm - Brachyury, endoderm - SOX17) compared to undifferentiated JOY6 pluripotent stem cells (blue).

Stability & Storage
Store the unopened product at -20 to -70 °C. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Do not use past expiration date.

Background: Pluripotent 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 vitro and 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.
