Localization by immunoelectron microscopy of somatostatin-containing cells in the gastric mucosa of a teleost fish, Perca fluviatilis.

abstract：:Primary cultures of cells from breast carcinomas were attempted in 74 cases. Growth was observed in 46 cases. Using immunochemical demonstration of keratin proteins (KER), epithelial membrane antigen (EMA) and carcinoembryonic antigen (CEA), three morphologically distinct cell populations were characterized and descri...

abstract：BACKGROUND INFORMATION:During apoptosis, the first morphological change is a distinct cell shrinkage known as the AVD (apoptotic volume decrease). This event is driven by a loss of intracellular K(+), which creates an osmotic gradient, drawing water out of the cell through AQPs (aquaporins). Loss of water in balance wi...
