Studies on the cellular basis of morphogenesis in the sea urchin embryo. Directed movements of primary mesenchyme cells in normal and vegetalized larvae.
TL;DR: It is suggested that the variations in the way in which the pattern is achieved are, in all probability, merely a reflexion of the lack of precision in the time sequence of changes in adhesive properties of the primary mesenchyme and blastocoel wall.

Studies on the cellular basis of morphogenesis in the sea urchin embryo
T. Gustafson,L. Wolpert +1 more
TL;DR: In this article, the cellular basis of the morphogenesis of the coelom, mouth, and the primary pore-canal in the sea urchin larva (Psammechinus miliaris ) has been studied by means of time-lapse cinematography.

An electron microscope study of the development of the blastula of the sea urchin embryo and its radial polarity
L. Wolpert,E.H. Mercer +1 more
TL;DR: An attempt has been made to correlate the changes in structure of the developing blastula, as revealed by electron microscopy, with events at both the molecular and cellular level, to provide clues to the basic polarity which becomes progressively enhanced by symmetric secretion of material from the cells.

Studies on the cellular basis of morphogenesis of the sea urchin embryo. Development of the skeletal pattern.
TL;DR: The ectoderm determines, via the mesenchyme cells, the major features of the skeletal pattern which, in other words, reflects the changing pattern of adhesiveness of the ectODerm.

Studies on the cellular basis of morphogenesis of the sea urchin embryo: The formation of the blastula
TL;DR: Investigation of the formation of the blastula in the sea urchin Psammechinus miliaris from the 16-cell stage to hatching by time-lapse cinematography found that changes in cell shape at cleavage, the radial plane of Cleavage, and the attachment of the cells to the hyaline layer are sufficient to account for the main features of blastula formation.
