sentence1: For the analysis of expression at different stages of differentiation, data were obtained for 43 mouse samples in StemBase , originating from 16 studies with Affymetrix MOE430A microarray chips, as used in an Oct4 expression profiling study covering murine ESCs, embryonal carcinoma cell lines, and several early differentiated lineages.
sentence2: We investigated the patterns of expression of the Oct4-associated data set in cells at different stages of differentiation, including embryonic carcinoma, embryonic stem cells, embryoid bodies, and various differentiated cell types, on the basis of transcriptomics data.
