Abstract:
:The extent of emigration of cells from the bursa of Fabricius to the periphery was estimated. Per anum application of fluorescein isothiocyanate to label bursal cells in situ was used. Migrant cells can be visualized on frozen sections or cell suspensions of peripheral organs by their fluorescence. The data show that at 2-3 weeks after hatching about 5% of bursal cells leave the bursa per day. Since the bursal cells divide rapidly, this indicates that the vast majority (95%) of bursal cells die in situ. Cells that leave the bursa are surface IgM positive and go first to peripheral blood and later into B cell areas of spleen, thymus and cecal tonsils. The results are also discussed on the basis of their implication for the generation of antibody diversity in the chicken bursa.
