Egg envelope cytodifferentiation in the colonial ascidian Botryllus schlosseri.

open access: yes, 1993
The formation and cytodifferentiation of egg envelopes were studied at the ultrastructural level in blastozooids of Botryllus schlosseri. The process was divided into five recognized stages of oogenesis. First, the small young oocytes (stage 1) are contacted by scattered cells (primary follicle cells—PFC) which adhere to the oolemma at several ...

Invertebrate Chordata, collectively named Protochordata, are filter-feeding marine animals, including Cephalochordata and Urochordata. The latter are characterized by a planctonic or sedentary life-style and owe their alternative name of Tunicates to the test or tunic, the peculiar covering in which the body is embedded.

PHENOLOXIDASE IN THE COLONIAL ASCIDIAN BOTRYLLUS SCHLOSSERI (UROCHORDATA: ASCIDIACEA).

open access: yes, 1994
Phenoloxidase activity was revealed in blood cells of the compound ascidian Botryllus schlosseri. The enzyme activity was significantly increased after preincubation of blood lysate with trypsin, chymotrypsin or foreign carbohydrates and inhibited by the copper-chelating agents phenylthiourea and diethyldithio-carbamate.
