Abstract
Living mammalian cells are modified by subjecting them to the influence of the ions from a metal electrode, for example of silver, which is placed in contact with them and which is made electrically positive, and causing a low intensity direct current to flow through them. The cells, which are relatively specialized, such as normal mammalian fibroblasts, assume a simpler, relatively unspecialized form and come to resemble hematopoetic or marrow-like cells.
