Method of making embryoid bodies from primate embryonic stem cells
First Claim
Patent Images
1. A method for producing differentiated human cells from human embryonic stem cells, the method comprising:
- culturing human embryonic stem cells under conditions such that at least some of the cells adhere to a substrate;
removing the adhering colonies of the embryonic stem cells from the substrate in clumps;
then incubating the clumps in a container under conditions in which the clumps are essentially inhibited from attaching to the container and under conditions in which the clumps of embryonic stem cells coalesce into embryoid bodies; and
culturing the embryoid bodies to produce human differentiated cells.

Abstract
Primate embryoid bodies are formed from primate ES cells. The ES cells form clumps. One then removes the clumps, as clumps, and permits incubation under non-adherent conditions. The development of embryoid bodies from primate ES cells is dependent on maintaining the aggregation of cells, as individualized cells will rapidly die.
