Effect of type I IFNs on J2E erythroid cell viability.
J2E cells were washed free of serum, seeded at 3 × 105cells/mL, and stimulated with IFN subtypes at (A) 100 or (B) 1000 IU/mL. Percentage viable cells was determined by eosin exclusion at 48 hours of culture (statistical significance compared wtih unstimulated J2E cells, *P ≤ .05; **P ≤ .01; mean ± SE, n = 3).
