Development of the sense organs of the larva of Botryllus schlosseri

Journal of Morphology, 1935
AbstractA study of the development of the sense organs of the larva of Botryllus schlosseri to determine, if possible, any homologies between its sense organs and those of other types of ascidians such as Molgula and Ammaroucium, which have sense organs structurally very different.The statolith appears in the Botryllus embryo as a single club‐shaped ...

Environmental Effect on the Reproductive Effort of Botryllus schlosseri

2001
The reproductive effort of Botryllus schlosseri varies both within and between populations. Here we present evidence of an environmental affect on the reproductive effort of colonies from two locations on the Northeast coast of America. Colonies from the Damariscotta River had a decrease in both sperm and egg production when clonal replicates were ...

Preliminary studies of the complement system in Botryllus schlosseri.

2012
The complement system represents an important humoral component of the mammalian immune system. Complement components can be subdivided in 5 gene families: C3/C4/C5, Bf/C2, MASP/C1r-s, C6/C7/C8A/C8B/C9 and Factor I. Until 1884, it was generally believed that the complement system was an unique feature of vertebrates since all attempts to identify ...

Phagocytosis-induced apoptosis in the compound ascidian Botryllus schlosseri.

2014
Colonies of the ascidian Botryllus schlosseri contain three blastogenetic generations: functional zooids, their buds and budlets on buds. Generation change or take-over (TO) occur cyclically and assure the recurrent renewal of the colony. During these events, lasting 24-36 h, diffuse apoptosis occurs in zooid tissues, as indicated by morphological ...
