Understanding TeSR™ Media Family
Introduction to Pluripotent Stem Cells
Pluripotent stem cells (PSCs) are a unique class of stem cells with the capacity to differentiate into any cell type found within the body, given the right conditions. This remarkable ability to transform is valuable for various applications in regenerative medicine, disease modeling, and drug discovery. The harnessing of PSCs for therapeutic and research purposes depends heavily on the culture conditions they are maintained in. The TeSR™ family of feeder-free culture media, developed by STEMCELL Technologies, provides an advanced, reliable solution for cultivating human embryonic stem cells (hESCs) and induced pluripotent stem cells (iPSCs). For a seamless experience in selecting the right media for your needs, consider exploring all check options available.
Key Components of TeSR™ Culture Media
The success of hPSC culture relies on optimized media formulations that support the unique needs of pluripotent cells. TeSR™ media incorporate high-quality components, including growth factors, buffering agents, and vitamins essential for cellular growth and maintenance.
