Abstract

According to the cells localizing directly in germinal centers the direct precursor of germinal center cells is a large cell both in the chicken, where low density (larger) bursa cells show a better localization in germinal centers than do higher density (smaller) bursa cells,1 and in the rabbit where the larger cells of lower density of appendix localize in germinal centers whereas smaller cells localize in the corona of follicles.2 However, we cannot conclude from such findings whether the maturity of the donor cells is the determining factor or whether these findings mean only that blast B cells have a different localization pattern from small B cells. The other evidence presented at this meeting, concerning surface Ig markers (α and γ) of peanut agglutinin positive B cells from peripheral lymphoid tissue, representing primarily germinal center cells,3,4,5 suggests a greater maturity of these cells rather than an immature precursor nature, since these would be expected to bear μ. If, however, switching from μ to other Ig isotypes occurs through interaction between sister chromatids during mitosis, this process might occur in germinal centers and could possibly take place within the first mitosis of cells entering these structures.
