ヒト羊膜における物質透過機構, 透過様式の一端を解明する目的で, 外因性トレーサー (lanthanum nitrateおよびhorse radish peroxidase (HRP)) の羊膜透過能を超微形態学的に検討した. 正期産羊膜を lanthanum あるいは HRPを含む溶液と接触させ, これらトレーサーの羊膜内局在様式を電顕観察した. lanthanum および HRPは羊膜上皮細胞の intercellular space全域に入り込む像が観察された. pinocytosis像は認められなかつたが, 胞体の明るい羊膜上皮細胞においては胞体内へのHRPのdiffuseな入り込み像が観察された. 以上より, 羊膜上皮は lanthanum, HRPに対し高い透過能を有し, 物質の移動に対しては比較的疎な上皮であることが推察された. また, HRPに関して異なつた透過様式を有する2種の羊膜上皮細胞の存在することが示された.
