Effect of type I IFNs on J2E erythroid cell differentiation.
J2E cells were seeded at 5 × 104 cells/mL and stimulated with IFN subtypes at (A) 100 and (B) 1000 IU/mL. Hemoglobin production was measured by benzidine staining at 48 hours of culture. (statistical significance compared with unstimulated J2E cells, *P ≤ .05; **P ≤ .01; mean ± SE, n = 3).
