The electrical properties of single acinar cells isolated from rat pancreas were studied with the whole-cell tight-seal recording method. Under resting conditions, the relative permeabilities of Cl and K wereP cl/P K≅3. At 1 μM internal calcium, a Ca and voltage-dependent Cl conductance was activated. At 10 μM internal calcium, the major conductance was(More)
The effect of intracellular adenosine 3',5'-cyclic monophosphate (cAMP) on dye and electrical coupling was studied in T84 cells, a cell line often used as a model for epithelial cell fluid secretion. Injections of lucifer yellow (LY) into single cells within a cluster of control cells resulted in LY localization to 1.3 +/- 0.2 (mean +/- SE) cells within a(More)
BACKGROUND Environmental challenges might affect the maternal organism and indirectly affect the later ontogeny of the progeny. We investigated the cross-generation impact of a moderate heat challenge in chickens. We hypothesized that a warm temperature--within the thermotolerance range--would affect the hormonal environment provided to embryos by mothers,(More)
