The formation of calcareous skeletal elements by various echinoderms, especially sea
urchins, offers a splendid opportunity to learn more about some processes involved in the …

The endoskeletal spicules of sea urchin larvae are composed of calcite, a surrounding
extracellular matrix, and small amounts of occluded matrix proteins. The spicules are formed …

Soluble proteins in the scallop (Patinopecten yessoensis) foliated calcite shell layer were
characterized using biochemical and molecular biological techniques. SDS PAGE of these …

This book follows a precursor volume devoted to biological calci? cation,-sued by the CRC
Press, Boca Raton (Florida) in 1992. Several basic aspects of the calci? cation process were …

The endoskeleton of the sea urchin larva is a network of calcareous rods secreted by
primary mesenchyme cells (PMCs). In this study, we identified seven new biomineralization …

Cell–cell fusion occurs in a wide variety of developmental contexts, yet the mechanisms
involved are just beginning to be elucidated. In the sea urchin embryo, primary mesenchyme …

The formation of the skeleton is a central event in sea urchin morphogenesis. The skeleton
serves as a framework for the larval body and is the primary determinant of its shape …

Publisher Summary This chapter discusses the cellular mechanisms of morphogenesis in
the sea urchin gastrula. The sea urchin embryo has been historically important system for …

Holothuroidea, comprising the sea cucumbers, is the least studied class of extant
echinoderms, yet this group possesses a wealth of features of potential interest to …

Spicule matrix proteins are the products of primary mesenchyme cells, and are present in
calcite spicules of the sea urchin embryo. To study their possible roles in skeletal …
