The oral gland cells of oikopleura dioica tunicata appendicularia


, : The oral gland cells of oikopleura dioica tunicata appendicularia. Acta Zoologica (Stockholm) 62(3): 195-200

Light microscopic and EM studies showed that the oral gland cells have 2 quite different zones. Medially, the basal zone is in contact with body fluids and the endostyle. Its strongly pyroninophile cytoplasm contains the extremely digitated nucleus and numerous small mitochondria. Laterally, the apical zone contacts the epidermis and it may also send a process between epidermal cells and deliver cell fragments into the primordium of the new house. This cell zone contains numerous membranes. The oral gland cells are probably light producing glands. The membrane-rich cell fragments which are incorporated into the house wall may be the source of the bioluminescence which has been reported from empty houses. The ontogenetically related subchordal cells have a similar structure and it is possible that these cells are also light producers.
