A considerable challenge confronts any developing neuron. Before it can establish a functional and specific connection, it must extend an axon over tens and sometimes hundreds of microns through a complex and mutable environment to reach one out of many possible destinations. The field of axonal gui

## Abstract A calcium blocking agent, verapamil, and a Ξ²~1~βadrenoreceptor blocking agent, metoprolol, were administered alone or in combination to 4βdayβold chick embryos (HamburgerβHamilton developmental stage 24). Embryos coβadministered with verapamil (0.05 nmol) and metoprolol (0.1 or 1.0 nmol
The aim of the present study was to evaluate the effect of hypophysectomy on cell proliferation in the left ovary and the left testis of 8- to 14-day-old chick embryos. Hypophysectomy was performed by the partial decapitation technique. At 44-46 h of incubation, chick embryo heads were sectioned at
In recent years, the zebrafish Danio rerio has emerged as a powerful model organism for the study of vertebrate embryogenesis. Zebrafish, like other vertebrates, possess pigment cells that arise from two distinct embryonic sources: those of the dermis and epidermis originate from the neural crest, w
We have directly followed the formation of and the thymus colonization by pro-T lymphocytes in the developing C57BL/6 mouse embryo by using the monoclonal antibody JORO 37-5 specific for pro-T lymphocytes, immunofluorescence staining and flow fluorocytometry or microscopy analysis. The results show
