cGMP, feeder-free maintenance medium for human ES and iPS cells
What Our Scientist Says
It makes me proud knowing that my work is critical to keeping thousands of hPSC lines reliably healthy and consistent around the world.
Manufactured under relevant cGMPs, mTeSR™1 ensures the highest quality and consistency for reproducible results in your fundamental research, as well as for cell therapy and investigational new drug research applications. This serum-free, complete cell culture medium is made with pre-screened raw materials to ensure batch-to-batch consistency and robust performance in feeder-free hPSC culture.
Use established protocols for applications ranging from derivation to differentiation with this most widely published feeder-free hPSC culture medium, which has been used by leading pluripotent stem cell researchers to successfully maintain thousands of hPSC lines in over 50 countries. For enhanced cell performance and versatile maintenance, you may also be interested in mTeSR™ Plus medium, which is also manufactured under relevant cGMPs and features stabilized components and enhanced buffering.

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.
