Recent electron microscopic and biochemical investigations have revealed the pinocytotic uptake of extra ovarian proteins into the vitellogenic oocytes (Hinsch and Cone, 1969; Wolin et at., 1973). The uptake of these macromolecular yolk precursor substances could be demonstrated using trypan blue as well as horse radish peroxidase
