... miniata , to complement the recent analysis of two sea urchin species. We identified 20 cell states across six developmental stages from 8 hpf to mid-gastrula stage, using the analysis of 25,703 cells. The clusters were assigned cell states based on known marker gene expression and by in situ RNA...

Here, we leverage the sea urchin embryo for its well-established gene regulatory network to interrogate the embryo using...

...David R. McClay; Esther Miranda; Stacy L. Feinberg ABSTRACT Many marine larvae begin feeding within a day of fertilization, thus requiring rapid development of a nervous system to coordinate feeding activities. Here, we examine the patterning and specification of early neurogenesis in sea urchin...

...Zheng Wei; Lynne M. Angerer; Robert C. Angerer During embryogenesis the sea urchin early pluteus larva differentiates 40-50 neurons marked by expression of the pan-neural marker synaptotagmin B (SynB) that are distributed along the ciliary band, in the apical plate and pharyngeal endoderm, and 4-6...

.... However, the role of transporters in moving extracellular signals that regulate embryogenesis is largely unexplored. Here, we show that a mesodermal ABCC (MRP) transporter is necessary for endodermal gut morphogenesis in sea urchin embryos. This transporter, Sp -ABCC5a (C5a), is expressed in pigment cells...

..., however, that Vasa has a much broader function, including a significant role in cell cycle regulation. Results herein indicate that Vasa is utilized widely, and often induced transiently, during development in diverse somatic cells and adult precursor tissues. We identified that Vasa in the sea urchin...

... provides a valuable paradigm for understanding stem cells in general. We find that the PGCs of the sea urchin Strongylocentrotus purpuratus exhibit broad transcriptional repression, yet enrichment for a set of inherited mRNAs. Enrichment of several germline determinants in the PGCs requires the RNA-binding...

...Atsuko Yamazaki; Yumi Kidachi; Masaaki Yamaguchi; Takuya Minokawa Echinoids (sea urchins) are divided into two major groups – cidaroids (a ‘primitive’ group) and euechinoids (a ‘derived’ group). The cidaroids are a promising model species for understanding the ancestral developmental mechanisms...

A well-characterized gene regulatory network (GRN) in the sea urchin embryo was used to identify the transcription factors that control five distinct cell changes during EMT. Single transcription factors were perturbed and the consequences followed with in vivo time-lapse imaging...
