Human peripheral blood-derived eosinophils were assessed for their viability, density, and functional properties after 7 days of culture with purified mouse IL-5 and mouse 3T3 fibroblasts. Whereas none of the eosinophils remained viable after 7 days of culture in the absence of IL-5, 38 +/- 12% and 61 +/- 14% (n = 6, mean +/- SD) of the eosinophils survived in the presence of 1 pM IL-5 alone or 1 pM IL-5 in the presence of 3T3 fibroblasts, respectively (p less than 0.05).
