Detecting Symmetry in Ascidian Embryo
2024 IEEE International Symposium on Biomedical Imaging (ISBI)Modern microscopy techniques allow to acquire temporal sequences of 3D stacks. It provides a unprecedented means to image developing organs or embryos at the cellular level, but results in a huge quantity of data.Proposing efficient processing methods is then absolutely crucial. We are addressing here the study of ascidian embryo development.

The ascidian prophenoloxidase activating system [PDF]
Invertebrate Survival Journal, 2009 Phenoloxidases/tyrosinases initiate melanin synthesis in almost all organisms, and are involved in different biological activities such as the colour change of human hair and the browning or blackening of fruit skin etc.

Evolutionary mitogenomics of Chordata: the strange case of ascidians and vertebrates [PDF]
Invertebrate Survival Journal, 2009 The availability of almost one thousand complete mitochondrial genome (mtDNA) sequences of chordates provides an almost unique opportunity to analyse the evolution of this genome in the phylum Chordata, and to identify possible divergent evolutionary ...

Regeneration in Echinoderms and Ascidians
, 2010 The regenerative potential is expressed to a maximum extent in echinoderms and ascidians. They provide unique and valuable deuterostome models, closely related to vertebrates (man included), for an integrated approach exploring regeneration from tissue ...

Ascidian cytotoxic cells: state of the art and research perspectives [PDF]
Invertebrate Survival Journal, 2012 Ascidian cytotoxic cells are multivacuolated cells, variable in morphology, abundantly represented in the circulation, playing important roles in ascidian immunosurveillance.

Artificial seawater based long-term culture of colonial ascidians
, 2021 Tunicates are highly diverse marine invertebrate filter-feeders that are vertebrates' closest relatives. These organisms, despite a drastically different body plan during their adulthood, have a tissue complexity related to that of vertebrates. Ascidians,
