Resumen
Cultivation of macrophages and their progenitors has been very useful for elucidation of function, behaviour and morphology of these cells. The purpose of this contribution is to describe a new in vitro system (organoid, high density or micromass culture) which proved to be convenient for cultivation of macrophages derived from human synovial fluid and tissue and mouse peritoneal fluid. Using this method, highly differentiated and functionally active macrophages of marked purity and long maintenance (up to 2 weeks) could be obtained even after previous cultivation and subcultivation in monolayer culture. The macrophages were identified by electron rnicroscopy and immunomorphology using HLA-DR-DP, CD-68 (markers for human macrophages), anti-humanpolymorphonuclear leukocyte-gelatinase and F4/80 (a mouse macrophage surface marker). The significance of this method as a research tool in the study of cartilage degradation by macrophages in co-cultures is stressed.
