Overview

Use this specialized, feeder-free culture medium to achieve more consistent human pluripotent stem cell (hPSC) cultures with homogenous, undifferentiated phenotypes.

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.

Data Figures

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.

iPSC-Based Modeling of RAG2 Severe Combined Immunodeficiency Reveals Multiple T Cell Developmental Arrests. M. Themeli et al. Stem cell reports 2020 feb

Abstract

RAG2 severe combined immune deficiency (RAG2-SCID) is a lethal disorder caused by the absence of functional T and B cells due to a differentiation block. Here, we generated induced pluripotent stem cells (iPSCs) from a RAG2-SCID patient to study the nature of the T cell developmental blockade. We observed a strongly reduced capacity to differentiate at every investigated stage of T cell development, from early CD7-CD5- to CD4+CD8+. The impaired differentiation was accompanied by an increase in CD7-CD56+CD33+ natural killer (NK) cell-like cells. T cell receptor D rearrangements were completely absent in RAG2SCID cells, whereas the rare T cell receptor B rearrangements were likely the result of illegitimate rearrangements. Repair of RAG2 restored the capacity to induce T cell receptor rearrangements, normalized T cell development, and corrected the NK cell-like phenotype. In conclusion, we succeeded in generating an iPSC-based RAG2-SCID model, which enabled the identification of previously unrecognized disorder-related T cell developmental roadblocks.
One-Stop Microfluidic Assembly of Human Brain Organoids To Model Prenatal Cannabis Exposure. Z. Ao et al. Analytical chemistry 2020

Abstract

Prenatal cannabis exposure (PCE) influences human brain development, but it is challenging to model PCE using animals and current cell culture techniques. Here, we developed a one-stop microfluidic platform to assemble and culture human cerebral organoids from human embryonic stem cells (hESC) to investigate the effect of PCE on early human brain development. By incorporating perfusable culture chambers, air-liquid interface, and one-stop protocol, this microfluidic platform can simplify the fabrication procedure and produce a large number of organoids (169 organoids per 3.5 cm × 3.5 cm device area) without fusion, as compared with conventional fabrication methods. These one-stop microfluidic assembled cerebral organoids not only recapitulate early human brain structure, biology, and electrophysiology but also have minimal size variation and hypoxia. Under on-chip exposure to the psychoactive cannabinoid, $\Delta$-9-tetrahydrocannabinol (THC), cerebral organoids exhibited reduced neuronal maturation, downregulation of cannabinoid receptor type 1 (CB1) receptors, and impaired neurite outgrowth. Moreover, transient on-chip THC treatment also decreased spontaneous firing in these organoids. This one-stop microfluidic technique enables a simple, scalable, and repeatable organoid culture method that can be used not only for human brain organoids but also for many other human organoids including liver, kidney, retina, and tumor organoids. This technology could be widely used in modeling brain and other organ development, developmental disorders, developmental pharmacology and toxicology, and drug screening.
IGF1-mediated human embryonic stem cell self-renewal recapitulates the embryonic niche. S. E. Wamaitha et al. Nature communications 2020

Abstract

Our understanding of the signalling pathways regulating early human development is limited, despite their fundamental biological importance. Here, we mine transcriptomics datasets to investigate signalling in the human embryo and identify expression for the insulin and insulin growth factor 1 (IGF1) receptors, along with IGF1 ligand. Consequently, we generate a minimal chemically-defined culture medium in which IGF1 together with Activin maintain self-renewal in the absence of fibroblast growth factor (FGF) signalling. Under these conditions, we derive several pluripotent stem cell lines that express pluripotency-associated genes, retain high viability and a normal karyotype, and can be genetically modified or differentiated into multiple cell lineages. We also identify active phosphoinositide 3-kinase (PI3K)/AKT/mTOR signalling in early human embryos, and in both primed and na{\{i}}ve pluripotent culture conditions. This demonstrates that signalling insights from human blastocysts can be used to define culture conditions that more closely recapitulate the embryonic niche."
