Use of an extracellular, ion-selective, vibrating microelectrode system for the quantification of K+, H+, and Ca2+ fluxes in maize roots and maize suspension cells
An ion-selective vibrating-microelectrode system, which was originally used to measure extracellular Ca2+ gradients generated by Ca2+ currents, was used to study K+, H+ and Ca2+ transport in intact maize (Zea may...

Monensin interferes with the determination of the mesodermal cell line in embryos of Patella vulgata
In embryos of the equally cleaving marine gastropod Patella vulgata, the mesodermal stem cell is determined during the interval between the fifth and sixth cleavage by means of cellular interactions between one o...

The presence of an extracellular matrix between cells involved in the determination of the mesoderm bands in embryos ofPatella vulgata (Mollusca, gastropoda)
In 32-cell stage embryos ofPatella vulgata one of the macromeres contacts the animal micromeres, and as a result is induced to differentiate into the stem cell of the mesodermal cell line. In this study we show t...
