Abstract

A method of perfusion organ culture is described in which explants cultured at the air-medium interface are bathed by a continuous flow of nutrient medium. Morphological studies on the fetal rat lung indicate that explant development in this system is comparable to that obtained using standard organ-culture dishes. Medium supply is easily manipulated and continuous sampling of the effluent stream is possible without disturbing the immediate explant environment. The basic design facilitates secretory-response studies on cultured organ explants as demonstrated by a study of glucose-stimulated insulin release by the neonatal rat pancreas.
