title: Differentiation of an Abelson virus-transformed immature B precursor cell line under the expression of tyrosine kinase activity of v-abl oncogene product.
abstract: The expression of v-abl oncogene during the in vitro differentiation of an Abelson-virus-transformed immature B precursor cell line from immunoglobulin-null to intracytoplasmic mu-positive cells and further to intracytoplasmic gamma 2b-positive cells was examined. The results showed no significant alteration in the amounts and tyrosine kinase activity of v-abl oncogene product during differentiation, indicating that B cell differentiation processes are independent of v-abl functions.
