HbF and HbA2 production in ErPC cultures of 14 β-thalassemia and SCA patients after 4 and 8 days differentiation. The hemoglobin levels were analyzed by HPLC and the percentage values obtained indicated. The upper panel shows the average ±SD of the samples presenting HbF >50 % and the lower panel shows the average of the samples with HbF <50 %, n number of ErPC samples
