Feeder-independent culture systems for human pluripotent stem cells.

The continued success of pluripotent stem cell research is ultimately dependent on access to reliable and defined reagents for the consistent culture and cryopreservation of undifferentiated, pluripotent cells. The development of defined and feeder-independent culture media has provided a platform for greater reproducibility and standardization in this field. Here we provide detailed protocols for the use of mTeSR™1 and TeSR™2 with various cell culture matrices as well as defined cryopreservation protocols for human embryonic and human induced pluripotent stem cells.
