Tissue homeostasis in sponges: quantitative analysis of cell proliferation and apoptosis. Halisarca dujardinii
Listed in Teesside University Research Data Repository
Here we provide data underlying the upcoming publication "Tissue homeostasis in sponges: quantitative analysis of cell proliferation and apoptosis".
Description
These data provide a quantitative description of cell proliferation and apoptosis in intact tissues of marine sponge, Halisarca dujardinii (class Demospongiae). Tissues of Halisarca are highly proliferative, indicating either high rates of cell turnover or body growth.
The main fraction of proliferating cells are choanocytes, food-entrapping flagellated cells of the aquiferous system. They also seem to be the main source of new mesohyl cells. The numbers of apoptotic cells in intact tissues are insignificant; both choanocytes and mesohyl cells undergo apoptosis.
