Fig. 1From: SoxB2 in sea urchin development: implications in neurogenesis, ciliogenesis and skeletal patterningSoxB1 and SoxB2 genes expression in S. purpuratus during first week of development. Colorimetric (a–a′, b–b′, c–c′, d–d′, e–e′, f–f′, g–g′, h–h′, i–i′) and double fluorescent (a″, b″, c″, d″, e″, f″, g″, h″) SoxB1 and SoxB2 in situ hybridizations in embryos at 24–144 hpf. Fluorescent in situ hybridizations: SoxB1 is green and SoxB2 is red. The nuclear marker DAPI is shown in blueBack to article page
