Key Applications of TeSR™ Media
Human Pluripotent Stem Cell (hPSC) Maintenance
TeSR™ media provide a robust platform for the maintenance of hPSCs, offering the conditions necessary for self-renewal and expansion. The formulations ensure cells remain in a pluripotent state, supporting ongoing research into cell behavior, genomic integrity, and potential therapeutic applications.
Reprogramming Techniques for iPSCs
In the realm of regenerative medicine, reprogramming somatic cells into iPSCs offers the potential to derive patient-specific cells for therapeutic purposes. TeSR™ media specifically support this transition through formulations like ReproTeSR™, which employs a unique combination of signaling molecules and factors to facilitate efficient reprogramming.
Optimizing Differentiation Processes
The differentiation of hPSCs into specialized cell types is a critical area of research. The STEMdiff™ suite of differentiation media utilizes TeSR™ formulations to provide optimized conditions that guide hPSCs to differentiate into various lineages, including neurons, cardiomyocytes, and blood progenitors. These media incorporate essential growth factors to enhance the efficiency and reproducibility of differentiation.
