鶏胚内耳tegmentum vasculosumの発生およびK⁺-NPPase活性の局在

抄録

The Localization of Na⁺, K⁺-ATPase activity was demonstratesd in the developing tegmentum vasculosum of the chick cochlea. At stage 37 epithelial folds (Lamellae) were relatively well developed. Light and dark cells were identified ultratructurally. At stages 41 to 42, K⁺-NPPase activity showing Na⁺, K⁺-ATPase appeared in the folded cytoplasmic processes of the dark cell. At stages 45 to 1 day old the number of mitochondria in the dark cell increased. The convoluted basolateral infoldings were highly developed. K⁺-NPPase activity was limited to the cytolpasmic processes of the dark cell.
