[Stages of organogenesis and cytodifferentiation of the albumen gland in the snail Helix aspersa Muller].
The differentiation of the albumen gland of the pulmonate stylommatophora Helix aspersa has been divided into five stages. An ultrastructural study showed, the differentiation of undifferentiated epithelial cells into two cell types: ciliated cells and secretory cells. The glandular differentiation of epithelial cells was characterized by the development of ergastoplasma and the Golgi apparatus which were both involved in protein and galactogen synthesis.
