Introduction to TeSR™ Feeder-Free Media
In the realm of stem cell research, the use of high-quality culture media is crucial for maintaining and differentiating human pluripotent stem cells (hPSCs). One of the most recognized solutions for this is the TeSR™ family of feeder-free media. Developed for the cultivation of human embryonic stem (hES) and induced pluripotent stem (iPS) cells, TeSR™ media provides a robust alternative to traditional feeder-layer techniques. The rigorous formulations stemmed from collaborative research initiatives led by notable scientists like Dr. James Thomson, ensuring that researchers can conduct experiments with high reproducibility and minimal variability in cell behavior. Within this context of advanced research, the TeSR™ media ecosystem has established itself as a comprehensive solution for all stages of stem cell research, from reprogramming to differentiation and cryopreservation.

What are TeSR™ Media Components?
TeSR™ media is meticulously formulated with a blend of essential components pivotal for the growth and maintenance of hPSCs. Key elements include basic nutrients, growth factors like fibroblast growth factor-2 (FGF2), and specific proteins designed to keep the cells in a pluripotent state. Each component is pre-screened for consistency and effectiveness, ensuring that the medium supports optimal cellular functions. The media formulations are built on years of research and are adapted to provide not just basic sustenance to the cells, but also to facilitate their growth in a controlled environment. Importantly, the composition is tailored to minimize potential sources of variability, which is a critical factor in experimental success.
Overview of Feeder-Free Cultivation Benefits
The advantages of feeder-free cultivation using TeSR™ media are manifold. Firstly, it eliminates the variables introduced by feeder layers, such as contamination and batch-to-batch inconsistencies. This not only simplifies the handling procedures but also enhances reproducibility in experiments. Secondly, feeder-free systems support better morphology maintenance, allowing for more accurate assessments of hPSC characteristics. Lastly, feeder-free culture conditions facilitate large-scale expansion of hPSCs, crucial for potential clinical applications where significant quantities of these cells are necessary.
Understanding the Role of hPSCs
Human pluripotent stem cells (hPSCs) possess the unique ability to differentiate into any cell type in the body, making them invaluable for regenerative medicine and therapeutic development. They are characterized by their self-renewal and pluripotent capabilities which are preserved in culture with the appropriate media. Understanding the biological and functional relevance of hPSCs is paramount for leveraging their potential in scientific research. TeSR™ media supports maintaining these intricate properties, ensuring that the cells not only survive but thrive in vitro.
Types of TeSR™ Media
TeSR™ Maintenance Media: All Variants Explained
The TeSR™ family consists of several variants, each designed to meet specific needs within hPSC research. Among the foremost is mTeSR™1, which has set a benchmark for feeder-free culture of hPSCs and has been extensively cited in peer-reviewed studies. Its formulation is tailored to enhance cell survival and growth while supporting pluripotency. Following its success, new products such as mTeSR™ Plus and TeSR™-AOF emerged to address particular laboratory needs, including a focus on stability and minimized animal-derived components.
In addition, mediums like TeSR™-E8™, recognized for its simplicity, contain the essential components necessary for hPSC maintenance without extraneous additives. This focus on minimalism aids researchers in understanding core cellular processes without the noise of additional factors. Similarly, TeSR™-E7™ is optimized for iPS cell reprogramming, providing an effective entry point into pluripotency.
