TeSR™

With the TeSR™ Family of Human ES and iPS Cell Culture Media

The TeSR™ family of feeder-free media are produced using rigorously pre-screened materials to ensure the highest levels of batch-to-batch consistency and experimental reproducibility, allowing you to minimize variation in your research. Each medium is based on published formulations1-3 from the laboratory of James Thomson, and allows researchers to maintain high quality human pluripotent stem cell (hPSC) culture systems. These products provide a continuous TeSR™ media-based workflow, from generation of induced pluripotent stem (iPS) cells, to maintenance, differentiation and cryopreservation of embryonic stem (ES) and iPS cells.

Why Use mTeSR™1 and the TeSR™ Media Family?

  • Feeder-free hPSC culture minimizes variability by limiting the presence of undefined components and immunogenic material.
  • mTeSR™1 is the most widely published medium for hPSC culture with > 1100 peer-reviewed publications.
  • The same base formulation in each medium allows for establishment of a continuous TeSR™ media-based workflow.

What Are the Functions of Cytokines in TeSR™ Media and Their Impact on hPSC Culture?

  • promotes cell survival and proliferation, while also inhibiting differentiation to specific lineages (e.g. cardiomyocytes). It is present in all of our TeSR™ media (except for TeSR™-E5).
  • is an important cytokine for hPSC self-renewal and expansion and can be found in the TeSR™ reprogramming (ReproTeSR™, TeSR™-E7™) and maintenance (mTeSR™1, TeSR™2, TeSR™-E8™) media.
  • inhibits reprogramming and is important for maintenance of hPSC pluripotency. TGFβ is found in all three TeSR™ maintenance media (mTeSR™1, TeSR™2, TeSR™-E8™).

Brand History

In 2006, Dr. Tenneille Ludwig and colleagues of Dr. James Thomson’s lab at the University of Wisconsin reported the derivation of a new ES cell line in fully defined, feeder-free culture conditions.1,2 This first defined medium significantly improved human ES cell culture, and was commercially released as mTeSR™1, becoming the most widely-published feeder-free medium, used in over 1100 peer-reviewed publications. Later, a xeno-free medium based on the same formulation was released as TeSR™2. In 2012, a new, low protein maintenance medium called TeSR™-E8™ was released. Based on the E8 formulation3 published by Dr. Guokai Chen of Dr. James Thomson’s lab, TeSR™-E8™ contains only the most essential media components required, thereby providing a simpler medium for maintenance of hPSCs.

In addition to TeSR™ maintenance media, STEMCELL Technologies has developed TeSR™-based media to support other facets of the pluripotent stem cell research workflow, including media optimized for reprogramming fibroblasts (TeSR™-E7™), reprogramming blood cell types and fibroblasts (ReproTeSR™), differentiation (TeSR™-E6 and TeSR™-E5) and cryopreservation (mFreSR™ and FreSR™-S).
