cGMP, feeder-free maintenance medium for human ES and iPS Cells
From: 272 USD



mTeSR™1, now manufactured under cGMP, is the most widely published feeder-free cell culture medium for human embryonic stem cells (ES cells) and induced pluripotent stem cells (iPS cells), with established protocols for applications ranging from derivation to differentiation. It has been used to successfully maintain thousands of ES and iPS cell lines in over 50 countries, and has supported top pluripotent stem cell publications and researchers. mTeSR™1 is a highly specialized, serum-free and complete cell culture medium. With pre-screened raw materials that ensure batch-to-batch consistency and robust feeder-free protocols for ES and iPS cell culture, mTeSR™1 provides more consistent cultures with homogeneous, undifferentiated phenotypes.

mTeSR™1 is manufactured under a cGMP quality management system compliant to 21 CFR 820, ensuring the highest quality and consistency for reproducible results.

Data and Publications


Figure 1. Normal hES and hiPS Cell Morphology is Observed in cGMP mTeSR™1 Cultures

Undifferentiated (A) H1 human embryonic stem (hES) and (B) WLS-1C human induced pluripotent stem (hiPS) cells cultured on Corning® Matrigel® Matrix in cGMP mTeSR™1 retain the prominent nucleoli and high nuclear-to-cytoplasmic ratio characteristic of this cell type after 10 passages. Densely packed cells and multi-layering are prominent when cells are ready to be passaged.

Figure 2. High Expansion Rates are Observed in cGMP mTeSR™1 Cultures

Graph shows the average fold expansion per passage +/- SEM obtained for hES (H1 and H9) and hiPS (WLS-1C) cells cultured in cGMP mTeSR­™1 (red) or non-cGMP mTeSR™1 (gray) on Corning® Matrigel® Matrix over 10 passages. Expansion was determined by enumerating the cell aggregates obtained at harvest and dividing by the number of cell aggregates seeded. Note that this data is representative of cultures passaged after 6-7 days in culture, lower expansion should be expected if using shorter culture times.

Figure 3. Cells Cultured in cGMP mTeSR™1 Medium Express Undifferentiated Cell Markers

Histogram analysis for hES (H1 and H9) and hiPS (WLS-1C) cells characterized using FACS for undifferentiated cell markers, OCT4 (OCT3) (Catalog #60093) and TRA-1-60 (Catalog #60064), after 8 - 10 passages in cGMP mTeSR™1 (filled = sample, blank = isotype control).

Figure 4. hPSCs Maintained in cGMP mTeSR™1 Display a Normal Karyotype

Karyograms of (A) H1 hES and (B) WLS-1C hiPS cells cultured in cGMP mTeSR™1 for 11 passages shows that a normal karyotype is retained.
