[Immunoreactive neuropeptides in cell lines derived from nervous and non nervous tissues]

Immunoreactive neuropeptides have been found in cells of permanent lines originating from nervous (cerebellum, retina) and non nervous (mesenchyme, kidney, bladder, colon, lung, melanocyte) tissues. The pattern of neuropeptides varied from one cell type to another, but all the cell lines studied contained immunoreactive alpha-endorphin and methionin-enkephalin.
