Aging in the colonial chordate, Botryllus schlosseri
What mechanisms underlie aging? One theory, the wear-and-tear model, attributes aging to progressive deterioration in the molecular and cellular machinery which eventually lead to death through the disruption of physiological homeostasis. The second suggests that life span is genetically programmed, and aging may be derived from intrinsic processes which enforce a non-random, terminal time inte...
متن کاملInsights on cytotoxic cells of the colonial ascidian Botryllus schlosseri
Morula cells (MCs) represent the most abundant circulating hemocyte of the compound ascidian Botryllus schlosseri. They are cytotoxic cells involved in the rejection reaction between contacting, genetically incompatible colonies. Upon the recognition of foreign substances, they degranulate and release their content, which contribute to the cell death along the contact borders. A major role in M...
متن کاملThe genome sequence of the colonial chordate, Botryllus schlosseri
Botryllus schlosseri is a colonial urochordate that follows the chordate plan of development following sexual reproduction, but invokes a stem cell-mediated budding program during subsequent rounds of asexual reproduction. As urochordates are considered to be the closest living invertebrate relatives of vertebrates, they are ideal subjects for whole genome sequence analyses. Using a novel metho...
متن کاملOrigin and Dispersal History of Two Colonial Ascidian Clades in the Botryllus schlosseri Species Complex
Human-induced global warming and species introductions are rapidly altering the composition and functioning of Earth's marine ecosystems. Ascidians (Phylum Chordata, Subphylum Tunicata, Class Ascidiacea) are likely to play an increasingly greater role in marine communities. The colonial ascidian B. schlosseri is a cryptic species complex comprising five genetically divergent clades (A-E). Clade...
متن کاملIn vitro delayed senescence of extirpated buds from zooids of the colonial tunicate Botryllus schlosseri.
In the colonial growth of botryllid ascidians, blastogenesis (bud formation) is a cyclical and synchronized developmental process characterized by a weekly rhythm of budding and apoptotic events. Very little is known about this cycle regulation and its control. In this study, the in vitro fate of developing buds and regressing zooids extirpated from Botryllus schlosseri colonies at different bl...
