Gap junction communication plays an essential role in follicle growth. Immunocytochemistry and confocal microscopy were used to examine the expression of gap junction connexins of the alpha and beta...
Intracellular pH in early Xenopus embryos: its effect on current flow between blastomeres.
1. Electrophysiological techniques were used to monitor the flow of electric current from one cell to the next in Xenopus laevis embryos between the 4-cell and early blastula stages of development....
The function of the sodium pump during differentiation of amphibian embryonic neurones.
1. A method has been developed for studying the differentiation in tissue culture of ectoderm and mesoderm derivatives, dissected from amphibian embryos which have just completed neurulation. 2....
Low resistance junctions between mesoderm cells during development of trunk muscles.
1. Electrical connexions between mesoderm cells have been examined during the formation of somites in Xenopus laevis, Bombina orientalis and Ambystoma mexicanum. 2. In Xenopus the resting potentials...
1. The mean resting membrane potential of cells in the neural plate of axolotl embryos increases from -25 to -45 mV (maximum values from -35 to -60 mV) when the embryos move from early to mid-neural...
1. Some membrane properties of endoderm and mesoderm cells isolated from late blastula stages of Xenopus laevis have been examined using electrophysiological techniques. 2. Cells were isolated by...

The action of melatonin on single amphibian pigment cells in tissue culture.
1. Neural crest material from neurula stage Xenopus embryos was tissue cultured as small aggregates of cells or a single cell suspension. Isolated pigment cells differentiated after 2 days in...

Pattern in the developing limb depends on signaling by polarizing region mesenchyme cells, which are located at the posterior margin of the bud tip. Here we address the underlying cellular...
