Derivation and propagation of human embryonic stem cell lines from frozen embryos in an animal product-free environment.

The protocols described here are comprehensive instructions for deriving human embryonic stem (hES) cell lines in xeno-free conditions from cryopreserved embryos. Details are included for propagation, cryopreservation and characterization. Initial derivation is on feeder cells and is followed by adaptation to a feeder-free environment; competent technicians can perform these simplified methods easily.

Derivation and feeder-free propagation of human embryonic stem cells under xeno-free conditions.

Background Aims: Human embryonic stem (hES) cells hold great potential for cell therapy and regenerative medicine because of their pluripotency and capacity for self-renewal. The conditions used to derive and culture hES cells vary between and within laboratories depending on the desired use of the cells. Until recently, stem cell culture has been carried out using feeder cells, and culture media, that contain animal products.

Safety paradigm: genetic evaluation of therapeutic grade human embryonic stem cells.

The use of stem cells for regenerative medicine has captured the imagination of the public, with media attention contributing to rising expectations of clinical benefits. Human embryonic stem cells (hESCs) are the best model for capital investment in stem cell therapy and there is a clear need for their robust genetic characterization before scaling-up cell expansion for that purpose. We have to be certain that the genome of the starting material is stable and normal, but the limited resolution of conventional karyotyping is unable to give us such assurance.
