Differences in In Vivo Functional Capacities of Avian Precursor B and T Cells Following In Vitro Incubation

Results of previous experiments in this laboratory have pointed to the possible existence of separate lineages of precursor T (PT) and precursor B (PB) cells in avian embryonic hematopoietic tissues (1,2). In view of these findings we have suggested that the bursa and thymus are not populated by multipotential stem cells (3,4), but rather, by cells already differentiated to the level of a committed PT and PB cell respectively. With this as a working model, we were interested in determining whether the postulated precursor cell populations displayed differential sensitivity to a variety of experimental procedures, resulting in a possible elimination of one of the two postulated cell types.
