Abstract
Official abstract text for this publication.
A process for obtaining human derived embryoid bodies (hEB). Human embryonic stem cells are incubated in vitro in a liquid growth medium under conditions in which the cells undergo differentiation, but do not adhere to the walls of the container. The invention also provides hEBs obtained by the process.
First claim
Opening claim text (preview).
The invention claimed is: 1. A process for obtaining at least one human-derived embryoid body (hEB), comprising: (a) providing human embryonic stem (hES) cells; (b) growing the hES cells in vitro suspended in a liquid growth medium in a vessel under conditions under which said cells undergo differentiation and said cells or aggregates thereof do not adhere to the vessel wall, wherein said conditions comprise culturing cells in a vessel having walls of a kind to which cells do not adhere; and (c) incubating for a time sufficient to develop hEBs from said cells.
