Germ cells (reproductive cells and their progenitors) give rise to the next generation in
sexually reproducing organisms. The loss or removal of germ cells often leads to sterility in …

Tunicates encompass a large group of marine filter‐feeding animals and more than half of
them are able to reproduce asexually by a particular form of nonembryonic development …

Colonial ascidians are the only chordates able to undergo whole body regeneration (WBR),
during which entire new bodies can be regenerated from small fragments of blood vessels …

Background Botryllid ascidians are a group of marine invertebrate chordates that are
colonial and grow by repeated rounds of asexual reproduction to form a colony of individual …

Ascidians are solitary or colonial marine invertebrates that share a common ancestor with
vertebrates and belong to the phylum Chordata. Colonial ascidians include more than 1,700 …

Colonial ascidians are marine invertebrate chordates that are the closest invertebrate
relative to the vertebrates. Colonies of Botryllus schlosseri undergo a continuous asexual …

Our understanding of sexual reproduction is mainly informed by research on gonochorists
(ie, species with separate sexes), including insects, birds, and mammals. But the male and …

Botryllus schlosseri, is a model marine invertebrate for studying immunity, regeneration, and
stress‐induced evolution. Conditions for validating its predicted proteome were optimized …

In this review, we introduce the concept of cell competition, which occurs between
heterogeneous neighboring cell populations. Cells with higher relative fitness become …

The vase tunicate, Ciona intestinalis (Linnaeus, 1767), is a social but non-colonial ascidian
that is implicated in biofouling of aquatic structures and destruction of the shellfish industry …
