Summary
The Bidder's organ of newly differentiated Bufo arenarum has the Bidderian oocyte, a round cell with a clear nucleus and numerous small vesicles, cisternae and ramified tubules in the cytoplasm. The surface of this cell periodically develops a tuft of microvilli protruding into the follicular cells that completely surround the oocyte. Between these two cellular types there is a junctional complex with a typical desmosome, and a junctional fascia similar in morphology to an intermediate junction.
