Experiments on beta-mercaptoethanol as an inhibitor of neurulation movements in amphibian larvae.
The morphogenetic movements of the ectoderm during neurulation include: (1) the movements taking place within the neural plate, which becomes longer and more concentrated in a medio-lateral direction (Jacobson, 1962); and (2) those found in the lateral epidermis layer which, in an epibolic way, moves in a dorsal direction, thus exerting a pushing effect on the lateral edges of the neural plate ...

متن کاملSuccessful cryopreservation of in vitro derived bovine blastocysts in microcapillary pipette tips
The open pulled straw has been used effectively to vitrify preimplantation embryos because of geometricfeatures that allow rapid rates of temperature exchange. One possible inexpensive alternative to the openpulled straw are commercially-available microcapillary pipette tips commonly used for electrophoresis. Themain purpose of this study was to compare the survival rates of in vitro produced b...
متن کاملRegional requirements for Dishevelled signaling during Xenopus gastrulation: separable effects on blastopore closure, mesendoderm internalization and archenteron formation.
During amphibian gastrulation, the embryo is transformed by the combined actions of several different tissues. Paradoxically, many of these morphogenetic processes can occur autonomously in tissue explants, yet the tissues in intact embryos must interact and be coordinated with one another in order to accomplish the major goals of gastrulation: closure of the blastopore to bring the endoderm an...
