title: Molecular analysis of a pro-T cell clone transformed by Abelson-murine leukemia virus, displaying progressive gamma delta T cell receptor gene rearrangement and surface expression.
abstract: We present a molecular analysis of T cell differentiation in a set of clones derived from in vitro Abelson murine leukemia virus (A-MuLV) infection of fetal liver cells. The parental clone had partial rearrangement of the beta and gamma loci and spontaneously displayed progressive rearrangement of V gamma genes during in vitro culture. Further differentiation of these clones leading to delta gene rearrangement and CD4 expression, then CD8, CD3 and T cell receptor gamma delta chain surface expression was obtained after intrathymic transfer followed by in vitro co-culture with thymic tissue. These A-MuLV clones, therefore, appear to represent a powerful model system for studying the early molecular events of T cell development at the clonal level.
