The aim of this study was to assess the suitability of various antihuman antibodies directed against immunocomponent cells to identify components involved in cellular and humoral immune responses in the immune organs of a female baboon, and to use these reagents to analyze the immunobiology of its reproductive tract. A female baboon of reproductive age was euthanized in the luteal phase of the menstrual cycle, and samples of spleen, intestines, tonsil, lymph nodes, Fallopian tube, uterus, cervix, and vagina were removed. Tissues were either fixed in 10% unbuffered formaldehyde, Bouin’s fluid, or 95% ethanol containing 5% glacial acetic acid, and embedded in paraffin, or frozen unfixed. Frozen sections were then fixed in 100% acetone. Subsequently, tissue sections were reacted with the following antihuman antibodies directed against CD3, CD45RA, CD45RO, CD4, CD8, CD20, CD68, HLA‐DR, CD57, CD103, CD15, and TIA‐1: IgA, IgG, IgM, J‐chain, secretory component, and neutrophil elastase, using routine immunohistology techniques. Human tissues (spleen, small intestine, lymph node, and tonsil) were used as positive controls. All antihuman antibodies crossreacted with baboon tissues, except neutrophil elastase, CD15, CD45RO, CD57, and CD1A. The distribution of immune cells in the reproductive tract of the female baboon was comparable to that in the human and offers the potential for this primate to be used as a model for the study of human reproductive immunology.
