Abstract
A new cell culture technique is described which is based on the observation that foils cast from the melamine resin hexamethylol-melamine-ether are suitable for the cultivation of beating heart muscle cells and fibroblasts of the rat. This foil can be flamed for sterilization, is about 80 nm in thickness, homogeneous and smooth, withstands dehydration and critical point-drying, can be removed from glass and permits the imaging of whole cells successively by light microscopy, transmission and scanning electron microscopy. The method is capable of narrowing the gap between light and electron microscopy, yielding excellent whole cell preparations in various kinds of microscopic studies to be performed on one and the same cell.
