A B-lymphoblastoid cell line ESKOL, composed of differentiated cells resembling hairy-cell leukemia (HCL) has been established from the peripheral blood (PB) of a HCL patient. Morphologically, ESKOL cells share several features with HCL B cells. Flow cytometric analysis revealed that ESKOL cells express HC2, CD21, PCA-1, CD24, FMC7, and CD25. Analysis by Northern-blot hybridization indicated that cultured cells expressed the oncogenes c-myc, H-ras and c-fos. RNA from 3T3 cells transfected with ESKOL DNA hybridized with H-ras and c-fos DNA probes. The ESKOL cells cultured in the presence of increasing concentrations, of alpha interferon demonstrated a decrease in the rate of cellular growth and an increase in the expression of CD21, CD25, FMC7 and PCA-1. Scanning electron microscopy revealed that cells incubated in the presence of alpha interferon underwent membranous changes with a loss of villosity. These observations suggest that IFN tends to drive HC out of their developmental arrest towards maturation.
