Abstract
Comparative ultrastructural study of the B-cells in the intimal layer of the synovial membrane in mouse, rat, rabbit, guinea-pig and man clearly distinguishes these cells from both the histiocytic A-cells (macrophage-like cells) and the fibroblasts. In addition to the marked development of the rough endoplasmic reticulum and Golgi apparatus, typical dense secretory vesicles apparently of Golgi origin are always found in mouse B-cells and frequently in those of the rat. These secretory characteristics clearly relate these cells to glandular cells engaged in polypeptidic secretion. The variations in the other species studied concern only the figuration of secretory material. Thus, the B-cells appear to constitute a category of secretory cells specific to the synovial membrane, but the function of which has yet to be determined.Entities:
