The Fetal Allograft Revisited: Does the Study of an Ancient Invertebrate Species Shed Light on the Role of Natural Killer Cells at the Maternal-Fetal Interface?

Clinical and Developmental Immunology, 2008
Human pregnancy poses a fundamental immunological problem because the placenta and fetus are genetically different from the host mother. Classical transplantation theory has not provided a plausible solution to this problem.

Phenoloxidase and cytotoxicity in the compound ascidian Botryllus schlosseri

Developmental & Comparative Immunology, 1998
The vacuoles of morula cells (MC) of the colonial ascidian Botryllus schlosseri contain phenoloxidase (PO). As the release of their vacuolar content at the border of incompatible contacting colonies is associated with the formation of necrotic masses which characterize the rejection reaction, the role of PO in Botryllus cytotoxicity was investigated ...

Toward a resolution of the cosmopolitan Botryllus schlosseri species complex (Ascidiacea, Styelidae): mitogenomics and morphology of clade E (Botryllus gaiae) [PDF]

, 2020
Botryllus schlosseri is a model colonial ascidian and a marine invader. It is currently recognized as a species complex comprising five genetically divergent clades, with clade A globally distributed and clade E found only in Europe.

'Cup cell disease' in the colonial tunicate Botryllus schlosseri [PDF]

Diseases of Aquatic Organisms, 2004
A new progressive, fatal disease called 'cup cell disease' was characterized in ex situ cultures of Botryllus schlosseri, a colonial tunicate. The disease originated as a few dark spots growing within zooids. The infected colonies then started to deteriorate, morphologically diagnosed by ampullar retraction, lethargic blood circulation and by a swollen

Cytochemical properties of Botryllus schlosseri haemocytes: indications for morpho-functional characterisation

European Journal of Histochemistry, 2009
In the present study, we carried out a detailed light microscopy investigation of the cytochemical properties of the haemocytes of the colonial ascidian Botryllus schlosseri, using new cytochemical stains and enzymatic markers, a panel of antibodies and ...

Biosensors for Biotoxins Detection and Monitoring

Advanced Sensor Research, Volume 5, Issue 6, June 2026.
This review examines state‐of‐the‐art biosensing platforms for biotoxin detection, including antibody‐, aptamer‐, CRISPR‐, nanopore‐, whole cells‐ and MIP‐based sensors. It highlights advances in ultra‐sensitive detection, real‐matrix validation in food and water, and multiplexed analysis, and discusses how the integration with machine learning ...

GENETIC AND DEVELOPMENTAL STUDIES ON BOTRYLLUS SCHLOSSERI

The Biological Bulletin, 1967
1. Properties of Botryllus schlosseri which give it outstanding promise for studies in developmental genetics are reviewed. 2. Laboratory culture procedures, in vitro fertilization, and a method for raising embryos in vitro are described. Controlled successions of complete life cycles can now be achieved in any laboratory. 3.

Morula Cells and Histocompatibility in the Colonial Ascidian Botryllus schlosseri [PDF]

Zoological Science, 1995
Abstract The role of morula cells (MC) in the formation of necrotic regions characterizing the rejection reaction between incompatible (i.e. nonfusible) colonies was investigated in the colonial ascidian Botryllus schlosseri. These blood cells share several chemical and histochemical properties with the pigment of the necrotic masses: both of them show
