(A) Graphic representation of hybridization intensity in pixels of 21 genes to the cDNA microarray.

Values for LRH are depicted by bars to the left; for Lin⁻Hoechst^Lowrhodamine^Bright(LRB), by bars to the right. Gene name or novel gene ID number is indicated to the left. (B) Southern blot of amplified cDNAs derived by reverse-transcription PCR of entire mRNA populations from 2 cell preparations from primary sorted mouse bone marrow cells. The samples in each lane are as indicated on the figure. The probes used for hybridization are listed to the right of each panel. Hybridization with β-actin serves as a control for loading.
