Regional specification during embryogenesis in the inarticulate brachiopod Glottidia
Article Abstract:
The embryogenesis of the lingulid brachiopod, Glottidia pyramidata, is described in terms of regional specification of the embryo. The animal half of the egg gives rise to the apical lobe and the dorsal valve of the larva, while the vegetal half gives rise to the mesoderm, endoderm and the site of gastrulation. Isolated animal halves during early cleavage did not gastrulate, but gave rise to epithelial vesicles, while isolation during the later stages of cleavage affected differentiation. In contrast, isolation of the vegetal halves at any time during cleavage had no effect on development.

Cloning and expression analysis of a novel mesodermally expressed cadherin
Article Abstract:
A study was conducted to examine the action of a novel cadherin expressed in mesodermal tissues compared to homotypic cadherins. Analysis of cahedrins cloned from mouse tissues showed that cadherin-11 expression restricted to mesenchymal tissues and cannot be found in the epithelia. It is suggested that cadherin 11 in the mouse is similar to cadherin-11 in humans, but is evolutionary distinct from other cadherin subfamilies.
