Macrophages and phagocytes clear proteolysis in the rat endometrium, with fluid potentially drained by venous capillaries as no lymphatic pre-capillaries were found.

This paper investigated how fluid and proteins are cleared in the rat endometrium, using ultrastructural methods to assess cellular mechanisms and potential lymphatic involvement. The authors report that resident macrophages and exudate phagocytes contribute to proteolysis through phagocytosis and via macro- and micropinocytosis, and they used exogenous tracer particles to look for evidence of endometrial prelymphatics. No ultrastructural evidence for endometrial prelymphatics was obtained, and the authors suggest that free tissue fluid may be drained through fenestrated (probably venous) blood capillaries. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Summary In the rat endometrium, resident macrophages and exudate phagocytes ensure proteolysis by means of phagocytosis, macro-and micropinocytosis. Using exogenous tracer particles no ultrastructural evidence could be obtained for the occurrence of endometrial prelymphatics. It is suggested that the free tissue fluid may be drained via the fenestrated (probably venous) blood capillaries. References Lauweryns, J., and Cornillie, F., preceding paper.
