Overview

STEMdiff™ Mesoderm Induction Medium (MIM) is a defined, xeno-free medium for generation of early mesoderm cells from human embryonic stem (ES) and induced pluripotent stem (iPS) cells. Protocols for mesodermal differentiation can be difficult and inconsistent, therefore, use the short and simple STEMdiff™ MIM monolayer protocol to differentiate your human pluripotent stem cells (hPSCs).

STEMdiff™ MIM is a complete medium that produces a cell population enriched for early mesoderm, as indicated by positive expression of Brachyury (T) and NCAM markers. As part of the hPSC workflow, STEMdiff™ MIM efficiently differentiates hPSCs cultured in TeSR™ media. When directed, early mesoderm cells produced using STEMdiff™ MIM can be further differentiated to specialized cell types, such as osteoblasts, chondrocytes, adipocytes or endothelial cells. For more information, see the data below.
Advantages:
• Defined and xeno-free


• Rapid induction of mesoderm in 2 - 4 days

Schematic of Mesoderm Induction Medium Differentiation Timeline

Figure 1. Schematic of Mesoderm Induction Medium Differentiation Timeline

On day 0, hPSC colonies are harvested and seeded as single cells at 5 x 10 4 /cm 2 in mTeSR™1 or TeSR™-E8™ and supplemented with 10 µM Y-27632. TeSR™ medium is replaced on day 1 with STEMdiff™ Mesoderm Induction Medium when cells are at approximately 20 - 50% confluency. Cells are then fed daily and cultured in STEMdiff™ MIM (days 2-4). Cells can be transferred to downstream differentiation conditions between days 3 - 5 or collected on day 5 for analysis.

STEMdiff™ MIM Generates a Homogenous Population of T + OCT4 - Early Mesoderm

(A) Data showing marker expression characteristic of the early mesoderm (positive Brachyury (T) expression and negative OCT4 and SOX 17 expression) on day 5 of the protocol. Data is expressed as a mean percentage of cells expressing each marker ± SD, n = 33 (T, OCT4), n = 5 (SOX17). (B) Expression of undifferentiated cell markers (OCT4, SOX2, NANOG) and early mesoderm markers (T, MIXL1, NCAM), measured by quantitative PCR (qPCR) and normalized to levels in undifferentiated cells, n = 2.

Mesoderm Differentiation and Cell Expansion are Efficient and Comparable Across Multiple hPSC Cell Lines

Graphs show mesoderm formation in multiple human ES (H1 and H9) and iPS (WLS-4D1, WLS-1C, STiPS-M001 and STiPS-F016) cell lines as measured by expression of Brachyury (T) and absence of OCT4. Cells maintained in (A) mTeSR™1 or (B) TeSR™-E8™ medium were differentiated using STEMdiff™MIM. (A, n = 2 - 10 per cell line, B, n = 3, data are expressed as a mean percentage ± SD) (C) Mesoderm differentiation on Corning® Matrigel® or Vitronectin XF™ is comparable. (n = 5, data are the mean percentage ± SD) (D) Average fold expansion of cells cultured in STEMdiff™MIM, as determined by cell yield / cells seeded. (n = 3 - 13. Error bars indicate SEM)

Phenotype of Cells Treated with STEMdiff™ MIM is Consistent with Early Mesoderm

Representative flow cytometry plots showing the switch from (A) EpCAM + NCAM -/low in hPSCs cultured in mTeSR™1 to (B) EpCAM -/low NCAM + expression in STEMdiff™ MIM-treated cells (day 5). EpCAM -/low NCAM + expression is characteristic of the early mesoderm. Expression of PDGFRα and KDR are low in both (C) hPSCs cultured in mTeSR™1 and (D) early mesoderm cells derived with STEMdiff™ MIM.
