From MEFs to Matrigel I: Passaging hESCs in the Presence of MEFs
Summary
This video demonstrates how to grow human embryonic stem cells (hESCs) on mouse embryonic fibroblast (MEF) feeder cells. Part 1 of 3.
Abstract
Protocol
Discussion
This video demonstrates how to grow human embryonic stem cells (hESCs) on mouse embryonic fibroblast (MEF) feeder cells. In the last step before plating, when the hESCs are resuspended, they should be of roughly uniform colony size and shape. Carefully pipette the hESC suspension up and down a few times to make the colonies smaller and more uniform, but not so much that single cells or very small colonies are generated.Immunofluorescence staining and microscopy or flow cytometry for hESC pluripotency markers, such as Oct…
