Abstract

To understand global features of gene expression changes during in vitro neural differentiation, we carried out the microarray analysis of embryonic stem cells (ESCs), embryonal carcinoma cells, and adult neural stem/progenitor (NS) cells. Expression profiling of ESCs during differentiation in monolayer culture revealed three distinct phases: undifferentiated ESCs, primitive ectoderm-like cells, and neural progenitor cells. Principal component (PC) analysis revealed that these cells were aligned on PC1 over the course of 6 days. This PC1 represents approximately 4,000 genes, the expression of which increased with neural commitment/differentiation. Furthermore, NS cells derived from adult brain and their differentiated cells were positioned along this PC axis further away from undifferentiated ESCs than embryonic stem-derived neural progenitors. We suggest that this PC1 defines a path to neural fate, providing a scale for the degree of commitment/differentiation.
