The Effects of j 8 - Mercaptoethanol on the Morphogenetic Movements of Amphibian Embryos

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 ...

Experiments on /3-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 ...

Stimulation of circus movement by activin, bFGF and TGF-β2 in isolated animal cap cells of Xenopus laevis

Lobopodium is a hyaline cytoplasmic protrusion which rotates circumferencially around a cell. This movement is called circus movement, which is seen in dissociated cells of amphibian embryos. Relative abundance of the lobopodia-forming cells changes temporally and spatially within Xenopus embryos, reflecting stage-dependent difference of morphogenetic movements. The lobopodia-forming activity o...

Effect of Beta-Mercaptoethanol on in Vitro Maturation and Development of Immature Mouse Oocytes

Purpose: This Study evaluated the resumption of meiosis, in vitro maturtion and department of immature mouse oocytes with b- mercaptothanol. Materials and methods: Immature oocytes were recovered from NMRI mouse strain (4-6 weeks) in different 4 experiments groups: the control group, the oocytes were matured in MEM-a+ medium containing + FCS 55%; group 1: the oocytes were matured in MEM- a med...
