in the present study , we have analyzed time courses of both quantity and density of the t-cell differentiation antigens , cd3 ( t3 ) , cd4 ( t4 ) , and cd8 ( t8 ) , as well as mhc antigens , on the cell surface of t cells , and made correlated measurements of dna content with the surface antigen quantity as well with rna content and cell size following activation of t cells by phytohemagglutinin .
