°Õ±ð³§¸éâ„¢ Feeder-Free Pluripotent Stem Cell (PSC) Culture Media
°Õ±ð³§¸éâ„¢ Pluripotent Stem Cell Culture Media
Feeder-Free Media for Human ES and iPS Cell Reprogramming, Maintenance, and Differentiation
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™ and the TeSR™ Media Family?
- Feeder-free hPSC culture minimizes variability by limiting the presence of undefined components and immunogenic material.
- m°Õ±ð³§¸éâ„¢ is the most widely published medium for hPSC culture with > 1500 peer-reviewed publications.
- The same base formulation in each medium allows for establishment of a continuous TeSR™ media-based workflow.

cGMP hPSC Maintenance Medium
Think forward to the clinic in your hPSC research. Our stabilized feeder-free hPSC maintenance medium, m°Õ±ð³§¸éâ„¢ Plus, is now manufactured and tested following relevant cGMPs under a certified quality management system. Find more information about regulatory compliance at º£½ÇÆƽâ°æ >
How is m°Õ±ð³§¸éâ„¢ Plus different from other maintenance media?
m°Õ±ð³§¸éâ„¢ Plus was designed based on the formulation of m°Õ±ð³§¸éâ„¢1. This version contains stabilized components including FGF2 and unlike other media offers enhanced buffering to reduce medium acidification so that cell quality is preserved during skipped media changes.
Advantages:
- Enhanced buffering and stabilized FGF2 support cell quality while allowing for alternate feeding schedules
- Supports superior culture morphology and cell growth characteristics
- Enables heightened single-cell survival when used with CloneRâ„¢
- Fully compatible with established genome editing and differentiation protocols
- Manufactured under relevant cGMPs, enabling a seamless transition from fundamental research to drug and cell therapy development

Consistent differentiation of ES and iPS cell lines can be challenging. We recommend our ³§°Õ·¡²Ñ»å¾±´Ú´Úâ„¢ suite of products for optimal and reproducible differentiation.
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 (, , ) media.
- inhibits reprogramming and is important for maintenance of hPSC pluripotency. °Õ³Ò¹óβ is found in all three TeSR™ maintenance media (, , ).
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 m°Õ±ð³§¸éâ„¢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 °Õ±ð³§¸éâ„¢2. In 2012, a new, low-protein maintenance medium called °Õ±ð³§¸éâ„¢-E8â„¢ was released. Based on the E8 formulation3 published by Dr. Guokai Chen of Dr. James Thomson’s lab, °Õ±ð³§¸éâ„¢-E8â„¢ contains only the most essential media components required, thereby providing a simpler medium for maintenance of hPSCs.
More recently, m°Õ±ð³§¸éâ„¢ Plus (2019) and °Õ±ð³§¸éâ„¢-AOF (Animal Origin-Free; 2021) have been released as part of º£½ÇÆƽâ°æ Technologies' °Õ±ð³§¸éâ„¢ product line. m°Õ±ð³§¸éâ„¢-Plus, a feeder-free maintenance medium, allows for weekend-free schedules and differs from m°Õ±ð³§¸éâ„¢1 in its enhanced pH buffering. °Õ±ð³§¸éâ„¢-AOF is guaranteed to be free of human and animal materials to the secondary level of manufacturing, providing users with peace-of-mind around viral safety. m°Õ±ð³§¸éâ„¢ Plus, °Õ±ð³§¸éâ„¢-AOF, and m°Õ±ð³§¸éâ„¢1 are all manufactured under relevant cGMPs.
In addition to °Õ±ð³§¸éâ„¢ maintenance media, º£½ÇÆƽâ°æ Technologies has developed °Õ±ð³§¸éâ„¢-based media to support other facets of the pluripotent stem cell research workflow, including media optimized for reprogramming fibroblasts (°Õ±ð³§¸éâ„¢-E7â„¢), reprogramming blood cells and fibroblasts (Repro°Õ±ð³§¸éâ„¢), differentiation (°Õ±ð³§¸éâ„¢-E6 and °Õ±ð³§¸éâ„¢-E5), and cryopreservation (³¾¹ó°ù±ð³§¸éâ„¢ and ¹ó°ù±ð³§¸éâ„¢-³§).
