In the cell line HT93A , which is capable of differentiating towards both the eosinophil and neutrophil lineages in response to retinoic acid ( RA ), C/EBPalpha mRNA expression decreased significantly concomitant with eosinophilic and neutrophilic differentiation , whereas C/EBPbeta expression was markedly increased.
