Expression of miR-130a and C/EBP-ε during human granulopoiesis. (A) mRNA expression of CEBPE, LTF, and CAMP (hCAP18) in human MB/PM, MC/MM, BC/SC, and PMN cells measured by real-time PCR. The highest value between the 4 populations was assigned the value 1, and the relative expressions of the other samples were recalculated accordingly. Asterisks indicate significant differences between the peak expression and the other populations during granulopoiesis (*P < .05). (B) C/EBP-ε and β-actin protein expression in the 4 populations examined by western blot. Error bars indicate SD between donors.
