Serial section images of Oikopleura dioica juvenile using SBF-SEM

The larvacean, Oikopleura dioica is a planktonic chordate, which is an emerging model organism with short life cycle of 5 days and belongs to tunicates (urochordates). Organ formation in the trunk proceeds in seven hours form hatching of tailbud larvae at three hours after fertilization (hpf) to completion of organ formation in fully functional juveniles that start feeding at 10 hpf and are just miniature of adult form. The dataset is serial section images of Oikopleura dioica juvenile that were obtained using SBF-SEM (Serial block face scanning electron microscopy). The 1961 TIFF images were compressed to a zip file.

The juveniles were fixed at 10.5 hours post fertilization, 30 min after the tail shift (Nishida, H., 2008 Development of the appendicularian Oikopleura dioica: culture, genome, and cell lineages. Dev. Growth Differ. 50, S239–S256.). The dataset would be used as a basic morphological data of this animal to explore organ structures and cellular composition at electron mic...
