Immunology &Cell Biology, Volume 103, Issue 1, Page 45-59, January 2025.Sea urchins are basal deuterostomes that share key molecular components of innate immunity with humans, and are a powerful model for the study of innate immunity. Here we characterize the morphology and associated molecular markers of immune cell types in a newly developed model sea urchin, Lytechinus pictus.
