A PROCESS TO STUDY CHANGES IN GENE EXPRESSION IN STEM CELLS

摘要

The present invention includes a method to identify stem cell genes that are differentially expressed in stem cells at various stages of differentiation when compared to undifferentiated stem cells by preparing a gene expression profile of a stem cell population and comparing the profile to a profile prepared from stem cells at different stages of differentiation, thereby identifying cDNA species, and therefore genes, which are expressed. The present invention also includes methods to identify a therapeutic agent that modulates the expression of at least one stem cell gene associated with the differentiation, proliferation and/or survival of stem cells.
