Organ culture of the postnatal mouse Crista ampullaris. Part I

The 2 day post partum mouse Crista ampullaris was cultured "in vitro" for 7 days. The differentiation into secretory and sensory areas was preserved. The ultrastructure of the dark cells of the secretory region was well maintained. The hair cell morphologically was considerably changed though the hair cells themselves survived 7 days in culture.
