Key Product Details
Summary for StemXVivo Endoderm Kit
A kit optimized to efficiently differentiate pluripotent cells into definitive endodermal cells under serum-free conditions.
Key Benefits
- Definitive endoderm differentiation in 4 days
- Pre-optimized to reduce experimental variation
- Endodermal cells are 70–90% positive for SOX17
- Endodermal cells express minimal to non-detectable levels of SOX7
Why Use Pre-optimized Reagents for Endoderm Differentiation?
Pluripotent stem cells can differentiate into all three germ layers including the definitive endoderm which gives rise to cells of the liver, lung, pancreas, and gut lining. Inefficient or inconsistent differentiation represents a costly and time-consuming obstacle in stem cell differentiation.
High quality media and defined differentiation supplements can reduce experimental variability and increase differentiation efficiency.
The StemXVivo® Endoderm Kit:
- Includes premium quality reagents that are optimized to induce endoderm differentiation in 4 days.
- Includes components with low lot-to-lot variation to reduce experimental variability.
- Yields definitive endodermal cells expected to be at 70–90% positive for SOX17.
- Yields an endodermal cell population with little to non-detectable SOX7 expression.
The StemXVivo® Endoderm Kit includes a serum-free, defined media supplement and premium quality recombinant proteins that have been optimized to efficiently differentiate pluripotent stem cells into definitive endodermal cells.
Cells are differentiated using two differentiation media that are made by combining the media supplement and the recombinant proteins included in this kit with RPMI medium. Differentiation Media I contains Activin A, FGF basic, and Wnt-3a whereas Differentiation Media II contains Activin A and FGF basic.

- Recombinant Human Activin A
- Recombinant Human FGF Basic
- Recombinant Human Wnt-3a
- Endoderm Marker: Goat Anti-Human SOX17 Antigen Affinity-purified Polyclonal Antibody
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.

Definitive Endoderm Differentiation of BG01V Human Embryonic Stem Cells. BG01V cells were differentiated into definitive endoderm using the media supplements included in this kit (Catalog # SC019B). To evaluate lineage commitment, the cells were stained with the Anti-Human SOX17 antibody included in this kit. The cells were stained with NorthernLights™557-Conjugated Donkey Anti-Goat IgG Secondary Antibody (R&D Systems, Catalog # NL001; red) and the nuclei were counterstained with DAPI (blue). |

The Differentiation of BG01V Human Embryonic Stem Cells into Definitive Endoderm Confirmed by Cell Markers (SOX17+/CXCR4+/FOX2A+/SOX7low). BG01V human embryonic stem cells were differentiated using the StemXVivo®Endoderm Kit (Catalog # SC019) and stained withA) a Goat Anti-Human SOX17 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1924),B) a Goat Anti-Human HNF-3 beta/FoxA2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2400), orC) a Goat Anti-Human SOX7 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF2766). In all images, cells were stained with the NorthernLights™557-conjugated Donkey Anti-Goat Secondary Antibody (Catalog # NL001, red) and the nuclei were counterstained with DAPI (blue). Endoderm-differentiated cells were also stained withD) a PE-conjugated Mouse Anti-Human CXCR4 Monoclonal Antibody (Catalog # FAB173P; filled histogram) or a PE-conjugated Mouse IgG2BIsotype Control (Catalog # IC0041P; open histogram). High levels of SOX17, CXCR4, and HNF-3 beta/FoxA2 combined with low levels of SOX7 indicate definitive endoderm differentiation. |

Differentiation of Human Amniotic Fluid Stem Cells into Definitive Endoderm.
The StemXVivo®Endoderm Kit (Catalog # SC019) was used to differentiate first-trimester human amniotic fluid stem cells (AFSCs) into definitive endoderm by culturing AFSCs in media containing recombinant human FGF basic, recombinant human Wnt-3a, and recombinant human Activin A for one day. On day 2, the media was removed and replaced with fresh media containing recombinant human FGF basic and recombinant human Activin A. The media was replaced twice daily until day 5 when cells were analyzed for expression of definitive endoderm markers.A.Before differentiation (day 0) AFSCs express the extra-embryonic endoderm marker SOX7, but not the definitive endoderm markers SOX17, HNF-3 beta, CXCR4, and GSC, as determined by quantitative real-time RT-PCR. After differentiation (day 5) into definitive endoderm, expression of SOX17, HNF-3 beta, CXCR4, and GSC was detected, but not expression of SOX7.***P< 0.001.B.Before differentiation (day 0) AFSCs fail to express the definitive endoderm marker CXCR4 as assessed by flow cytometry. However, after differentiation (day 5) the cells express CXCR4 (isotype control in black).***P< 0.001. |

Expression of SOX17 and HNF-3 beta in Human Amniotic Fluid Stem Cells Differentiated into Definitive Endoderm.
The StemXVivo®Endoderm Kit (Catalog # SC019) was used to differentiate first-trimester human amniotic fluid stem cells (AFSCs) into definitive endoderm by culturing AFSCs in media containing recombinant human FGF basic, recombinant human Wnt-3a, and recombinant human Activin A for one day. On day 2, the media was removed and replaced with fresh media containing recombinant human FGF basic and recombinant human Activin A. The media was replaced twice daily until day 5 when cells were analyzed for expression of definitive endoderm markers. Prior to differentiation (day 0), AFSCs show little to no expression of the definitive endoderm markers SOX17 and HNF-3 beta as assessed by confocal microscopy. However, after differentiation (Day 5), cells express both SOX17 and HNF-3 beta. The nuclei were stained with DAPI (blue). Scale Bar, 50 µm. |

Procedure Overview
This protocol is designed for BG01V human embryonic stem cells grown in Mouse Embryonic Fibroblast (MEF) Conditioned Media (Catalog # AR005). If using different cell lines or growth media, this protocol may need to be optimized.

Incubate at room temperature for 1-2 hours.
Plate BG01V human embryonic stem cells onto the coated plates at 3.3 x 103 cells/cm2 in MEF Media containing FGF basic.
Culture the cells overnight at 37 °C and 5% CO2. The next day each well should contain a tightly packed monolayer of cells
Day 1 of Differentiation

Add fresh MEF Conditioned Media containing FGF basic.
Incubate at 37 °C and 5% CO2 for a minimum of 2-4 hours prior to adding Differentiation Media I.
Remove the MEF Conditioned Media from each well.
Wash each well once with once with 1X PBS.
Add Differentiation Media I to each well and incubate overnight at 37 °C and 5% CO2.
Day 2 and 3 of Differentiation
Approximately 12-16 hours after adding Differentiation Media I, replace the media with Differentiation Media II.
Incubate Continue to replace Differentiation Media II every 8-12 hours.
Day 4 of Differentiation
On Day 4, the cells are ready for further differentiation to downstream cell types or analysis by immunocytochemistry and/or flow cytometry.
