CXCR4 mRNA expression during MK differentiation.
Representative results of CXCR4 mRNA expression analyzed by RT-PCR in HPCs after purification (97% CD34+) and during MK differentiation in the presence or absence of SDF-1α. Total RNA from CEM cell line and from UT-7 cell line was used as a positive (C+) and negative (C−) control, respectively. RT-PCR samples were normalized for Sp26.
