A small population of anterior cells patterns the forebrain during zebrafish gastrulation
Article Abstract:
The organizer is a cell group that sends signals which affect induction of neural tissue which later becomes the spinal cord and brain in vertebrates. The organizer was thought to induce tissue with forebrain character, and neural tissue from the trunk was thought to be posteriorized by other signals. A study of zebrafish shows that the anterior central nervous system is also dependent on ectodermal cells from the prospective head region for its development. These cells are needed for the anterior brain to survive, and for its patterning.

A fate map for the first cleavages of the zebrafish
Article Abstract:
The early cleavages of the zebrafish embryo can be traced using fluorescent dyes to make a fate map. The dyes are carried on particles of very high molecular mass. The fate map shows the development from primary cleavages to principal axes of the adult form. The first cleavage creates a dorsal and ventral partition, the second cleavage creates a left and right partition and the third cleavage creates an anterior and posterior partition.

LIgands for ErbB-family receptors encoded by a neuregulin-like gene
Article Abstract:
Neuregulins, arising from alternative RNA gene splicing, interact with the ErbB family of receptors, and aid the regulation of cell growth in tissues. A report of the cloning of neuregulin-2 with a similar motif structure to that of neuregulins, is described. It found that expression of neuregulin-2 is highest in the cerebellum through hybridization analysis of rat tissues, and that it has a different expression pattern.
