Human embryonic stem cells can be transformed into various cells in the body.The purpose of this research is to drive human embryonic stem cells toward neural lineage by using bone morphogenetic protein (bmp) antagonist.After 15 days, neural stem cells increase it by adding to basic fibroblast growth factor into a liquid cell culture. This study has successfully because the neural stem cells can change into derive neural progenitors. Thus, the researchers concluded that stem cells can be induced to develop human embryonic stem cells into the nervous system.
