cGMP, feeder-free maintenance medium for human ES and iPS Cells
From: 279 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.

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.

Establishment of an induced pluripotent stem cell (iPSC) line from a 9-year old male with autism spectrum disorder (ASD).

Varga E et al.


Peripheral blood mononuclear cells (PBMCs) were collected from a clinically characterized patient with autism spectrum disorder (ASD). The PMBCs were reprogrammed with the human OSKM transcription factors using the Sendai-virus delivery system. The pluripotency of transgene-free iPSCs was verified by immunocytochemistry for pluripotency markers and by spontaneous in vitro differentiation towards the 3 germ layers. Furthermore, the iPSC line showed normal karyotype. Our model might offer a good platform to study the pathomechanism of ASD, also for drug testing, early biomarker discovery and gene therapy studies.

Directed Differentiation of Human Pluripotent Stem Cells to Microglia.

Douvaras P et al.


Microglia, the immune cells of the brain, are crucial to proper development and maintenance of the CNS, and their involvement in numerous neurological disorders is increasingly being recognized. To improve our understanding of human microglial biology, we devised a chemically defined protocol to generate human microglia from pluripotent stem cells. Myeloid progenitors expressing CD14/CX3CR1 were generated within 30 days of differentiation from both embryonic and induced pluripotent stem cells (iPSCs). Further differentiation of the progenitors resulted in ramified microglia with highly motile processes, expressing typical microglial markers. Analyses of gene expression and cytokine release showed close similarities between iPSC-derived (iPSC-MG) and human primary microglia as well as clear distinctions from macrophages. iPSC-MG were able to phagocytose and responded to ADP by producing intracellular Ca(2+) transients, whereas macrophages lacked such response. The differentiation protocol was highly reproducible across several pluripotent stem cell lines.

Conserved roles of mouse DUX and human DUX4 in activating cleavage-stage genes and MERVL/HERVL retrotransposons.

Hendrickson PG et al.


To better understand transcriptional regulation during human oogenesis and preimplantation development, we defined stage-specific transcription, which highlighted the cleavage stage as being highly distinctive. Here, we present multiple lines of evidence that a eutherian-specific multicopy retrogene, DUX4, encodes a transcription factor that activates hundreds of endogenous genes (for example, ZSCAN4, KDM4E and PRAMEF-family genes) and retroviral elements (MERVL/HERVL family) that define the cleavage-specific transcriptional programs in humans and mice. Remarkably, mouse Dux expression is both necessary and sufficient to convert mouse embryonic stem cells (mESCs) into 2-cell-embryo-like ('2C-like') cells, measured here by the reactivation of '2C' genes and repeat elements, the loss of POU5F1 (also known as OCT4) protein and chromocenters, and the conversion of the chromatin landscape (as assessed by transposase-accessible chromatin using sequencing (ATAC-seq)) to a state strongly resembling that of mouse 2C embryos. Thus, we propose mouse DUX and human DUX4 as major drivers of the cleavage or 2C state.

Self-organized developmental patterning and differentiation in cerebral organoids.

Renner M et al.


Cerebral organoids recapitulate human brain development at a considerable level of detail, even in the absence of externally added signaling factors. The patterning events driving this self-organization are currently unknown. Here, we examine the developmental and differentiative capacity of cerebral organoids. Focusing on forebrain regions, we demonstrate the presence of a variety of discrete ventral and dorsal regions. Clearing and subsequent 3D reconstruction of entire organoids reveal that many of these regions are interconnected, suggesting that the entire range of dorso-ventral identities can be generated within continuous neuroepithelia. Consistent with this, we demonstrate the presence of forebrain organizing centers that express secreted growth factors, which may be involved in dorso-ventral patterning within organoids. Furthermore, we demonstrate the timed generation of neurons with mature morphologies, as well as the subsequent generation of astrocytes and oligodendrocytes. Our work provides the methodology and quality criteria for phenotypic analysis of brain organoids and shows that the spatial and temporal patterning events governing human brain development can be recapitulated in vitro.

Pyrimidoindole derivative UM171 enhances derivation of hematopoietic progenitor cells from human pluripotent stem cells.

Li X et al.


In the field of hematopoietic regeneration, deriving hematopoietic stem cells (HSCs) from pluripotent stem cells with engraftment potential is the central mission. Unstable hematopoietic differentiation protocol due to variation factors such as serums and feeder cells, remains a major technical issue impeding the screening of key factors for the derivation of HSCs. In combination with hematopoietic cytokines, UM171 has the capacity to facilitate the maintenance and expansion of human primary HSCs in vitro. Here, using a serum-free, feeder-free, and chemically defined induction protocol, we observed that UM171 enhanced hematopoietic derivation through the entire process of hematopoietic induction in vitro. UM171 facilitated generation of robust CD34(+)CD45(+) derivatives that formed more and larger sized CFU-GM as well as larger sized CFU-Mix. In our protocol, the derived hematopoietic progenitors failed to engraft in NOG mice, indicating the absence of long-term HSC from these progenitors. In combination with other factors and protocols, UM171 might be broadly used for hematopoietic derivation from human pluripotent stem cells in vitro.
