Multicellularity evolved multiple times independently during eukaryotic diversification 1-4 . Two distinct mechanisms underpin multicellularity 5 : clonal development (serial cell division of a single precursor cell) and aggregation (in which independent cells assemble into multicellular entity). Clonal aggregative are traditionally considered mutually exclusive 1,6-9 , evolutionary hypotheses have addressed why might diverge toward one or the other extreme 3,4 Both animals their sister...
ABSTRACT As the closest living relatives of animals, choanoflagellates offer insights into ancestry animal cell physiology. Here, we report isolation and characterization a colonial choanoflagellate from Mono Lake, California. The forms large spherical colonies that are an order magnitude larger than those formed by closely related Salpingoeca rosetta . In cultures maintained in laboratory, lumen colony is filled with branched network extracellular matrix colonized bacteria, including...

Sea cucumbers have an extraordinary regenerative capability. Under stressful conditions, Holothuria glaberrima can eviscerate their internal organs, including the digestive tract. From mesentery, a rudiment grows and gives rise to new intestine within few weeks. In last decades, cellular events that occur during intestinal regeneration been characterized, apoptosis, cell proliferation, muscle dedifferentiation. Nevertheless, contribution formation early growth of is unknown.Furthermore,...

To reconstruct role stem lineage, we set out to study choanoflagellates, closest living relatives animals 12 .
