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

open access: yesZoological 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

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, Volume 35, Issue 30, July 24, 2025.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

The complement system of Botryllus schlosseri [PDF]

open access: yes, 2017
Among the various effector mechanisms involved in immune responses, the complement system is one of the most ancient, deeply-rooted and important for its ability to orchestrate different cells and factors of both innate and adaptive immunity. The comprehension of its roots in the evolution is useful to understand how the main complement-related ...

Connectivity and Population Structure in a Marginal Sea—A Review

open access: yesDiversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim The current biodiversity crisis calls for conservation measures that limit or reduce the negative human impact on key habitats and vulnerable wild populations. To effectively protect biodiversity at all levels, including intra‐specific diversity, conservation measures should, ideally, be aligned with the connectivity and genetic structure ...

Unconventional secretion of a rhamnose-binding lectin by Botryllus schlosseri phagocytes

open access: yesThe European Zoological Journal
Botryllus schlosseri is a colonial tunicate diffuse in shallow waters of all seas and oceans. When B. schlosseri haemocytes are challenged with nonself, circulating phagocytes respond to the recognition of foreign molecules with the synthesis and ...

Fission in a colonial marine invertebrate signifies unique life history strategies rather than being a demographic trait

open access: yesScientific Reports, 2022
Each of the few known life-history strategies (e.g., r/K and parity [semelparity and iteroparity]), is a composite stratagem, signified by co-evolved sets of trade-offs with stochastically distributed variations that do not form novel structured ...

Interacting effects of environment and cultivation method on biofouling of farmed oysters (Crassostrea virginica)

open access: yesJournal of the World Aquaculture Society, Volume 56, Issue 3, June 2025.
Abstract Biofouling‐induced increases in labor costs are among the most impactful factors determining the technoeconomic feasibility and profitability of aquaculture operations. Understanding how different cultivation methods and environmental conditions influence the severity of biofouling is crucial to support informed decision‐making by farmers and ...

Morula cells and non-self recognition in the compound ascidian Botryllus schlosseri [PDF]

open access: yesInvertebrate Survival Journal, 2005
In the ascidian Botryllus schlosseri, we studied the effects of hemocyte incubation with foreign cells, such as bacteria, bacterial spores and yeast. In the presence of yeast and bacterial spores, morula cells, a common cell type in botryllid ascidians ...
