What is TeSR™ Media?
TeSR™ media represent a suite of advanced, feeder-free culture solutions designed for the maintenance, reprogramming, and differentiation of human pluripotent stem cells. These media are formulated to provide a microenvironment that supports the unique requirements of PSCs by striking an optimal balance of nutrients, growth factors, and cytokines. The result is a reproducible and consistent culture system that enhances cell viability and functionality. Variants such as mTeSR™1, mTeSR™ Plus, and TeSR™-E8™ provide specific advantages tailored to different research needs, making it essential for laboratories aiming for accuracy and efficiency in stem cell cultures.
Importance in Stem Cell Research
Pluripotent stem cells are pivotal not only in basic research but also in translatable therapeutic contexts. Their unique ability to differentiate into any cell type in the body provides researchers with immense potential for cellular therapies. However, maintaining the pluripotency and genomic integrity of these cells is paramount, which is where TeSR™ media become invaluable. By creating a controlled environment that can mimic physiological conditions, TeSR™ media mitigate factors leading to cell variability, thus ensuring high reproducibility across experiments and studies. Such rigor in culture techniques is crucial, particularly for applications in regenerative medicine, drug testing, and gene therapy.
Overview of Different TeSR™ Products
The TeSR™ family includes several products, each designed with specific features and use cases in mind. Key formulations include:
- TeSR™-E8™: A simplified, defined medium that reduces the number of components, allowing for easier handling and optimization of cell cultures.
- mTeSR™ Plus: An enhancement of mTeSR™1 with added buffering capabilities for better cell quality during skipped media changes.
- TeSR™-AOF: An animal origin-free version that guarantees safety concerns regarding contamination.

Benefits of Feeder-Free Culturing
Enhancing Cell Quality and Consistency
By eliminating the complications associated with feeder layers, which can introduce variability, TeSR™ media enhance the consistency and quality of stem cell cultures. This feed-free environment allows for optimal growth conditions, enabling researchers to maintain cells in their pluripotent state longer and with greater reliability. Furthermore, high-quality media formulations like mTeSR™1 and mTeSR™ Plus ensure that stem cells possess the necessary attributes—such as morphology and functionality—resembling in vivo conditions.
Reducing Contamination Risks
Contamination in cell cultures is a significant concern, often leading to experimentation failures and compromised results. TeSR™ media address this issue by providing a defined composition devoid of animal-derived components in its xeno-free formulations. This reduction in potential contaminants such as viruses and feeder-layer remnants results in greater safety for downstream applications such as transplantation and drug screening, allowing researchers to achieve more precise results.
Facilitating Scalable Research
As demand for scalable and reproducible PSC cultures increases, TeSR™ media enable researchers to transition from small-scale studies to larger bioreactor systems effortlessly. Media like mTeSR™3D and TeSR™-E8™3D are designed specifically for three-dimensional culture, promoting conditions that mirror in vivo environments and enhancing the efficacy of cellular clusters. This scalability fosters the development of new therapies while maintaining high-quality production standards.
Applications of TeSR™ Media in Research
Human Embryonic Stem (ES) Cell Culture
TeSR™ media have significantly impacted the culture of human embryonic stem cells, providing a robust environment for sustaining pluripotency. This application is pivotal for understanding early developmental processes and modeling human diseases. With consistent and reproducible ES cell lines, researchers can delve into everything from gene editing to drug discovery. The extensively validated performance of TeSR™ products ensures that researchers can depend on these media for reliable results.
Induced Pluripotent Stem (iPS) Cell Reprogramming
The capability to induce somatic cells into a pluripotent state has revolutionized regenerative medicine, allowing for the generation of patient-specific cell lines. TeSR™ media such as ReproTeSR™ facilitate this reprogramming process while maintaining essential growth conditions. As iPS technology continues to grow, researchers can focus on creating specific cell types for therapeutic use or disease modeling without worrying about the underlying cellular integrity.
Differentiation Techniques for Specific Cell Types
Beyond maintenance and reprogramming, TeSR™ media are integral to differentiating PSCs into various specialized cell types. For example, media like TeSR™-E5 and TeSR™-E6 are optimized for differentiating into different lineages, including cardiac or neural cells. This versatility is crucial for translational applications, where characterized and functional cell types are necessary for successful integration into therapeutic strategies, such as cell transplantation or tissue engineering.
