10. RT-PCR analysis of gene expression by BMP-4–treated ES cells
RT-PCR analysis of gene expression by BMP-4–treated ES cells.BM indicates rhesus monkey bone marrow cells; ES, undifferentiated ES cells; c, BMP-4–treated S17 cells; plus sign, BMP-4–treated ES cells; and minus sign, ES cells without BMP-4.
