Title: Improved culture of stem cells
Inventor: BERGENDAHL VELT
IPC: C12N5/0735
Filed: 2008-01-17
Abstract: While culture medium and systems have been described that permit the culture and proliferation of human embry-onic stem cells in feeder free and animal product free conditions, these conditions will not readily support cloning of an embryonic stem cell culture meaning, at least here, the initiation of a sub-culture using one or a very few originating cells. It has been found here that a class of small molecules that are inhibitors of kinase enzymes will increase the efficiency of cloning of stem cell cultures sufficiently to make such cloning practical in the defined medium and in other media as well.
