lymphoblast

 [lim´fo-blast]

lym·pho·blast

(lim'fō-blast),
A young immature cell that matures into a lymphocyte and is characterized by more abundant cytoplasm than in a lymphocyte, a nucleus in which the chromatin is finer than in a lymphocyte (but coarser than in a myeloblast), and one or two rather prominent nucleoli.
Synonym(s): lymphocytoblast
