Accumulation of macrophages in pregnant uterus appears to be caused in part by ovarian hormone-stimulated CSF-1 production and in part by others as yet unidentified uterine chemotactic factors. Recently, it was reported that macrophage inflammatory protein-1 α (MIP-1 α), one of β-chemokine subfamily whose target cells are T cells and macrophages, was expressed in mouse uterus throughout pregnancy. However, no morphological assessment has been performed yet. In this immunohistochemical study, we examined the spatio-temporal distribution of MIP-1 α positive cells in the mouse endometrium and decidua between days 0 and 8 of pregnancy, and obtained the following results. Firstly, the concentration of MIP-1 α positive cells in the periluminal area of endometrium (called primary decidua after implantation period) was low on days 0 and 3, and high on days 4 and 5, but not thereafter. Secondly, the concentration of MIP-1 α positive cells in the perimyometrial area of endometrium (called secondary decidua after implantation period) was high on days 3 to 8 thereafter. Lastly, most of MIP-1 α positive cells in the mouse endometrium during early pregnancy were macrophages. These changes of distribution of MIP-1 α positive macrophages may be involved in the successful conception in mice.}, pages = {33--40}, title = {妊娠初期のマウス子宮内膜におけるmacrophage inflammatory protein-1α(MIP-1α)の発現分布様式の検討}, volume = {16}, year = {2001}, yomi = {フジミヤ, ミネコ and アキヤマ, ミノル and ゴトウ, サカエ and タケバヤシ, コウイチ and ノダ, ヨウイチ} }
