A system for changing the morphology and function of adult mammalian cells in vitro and in vivo to produce embryonic stem cell types, including cells made by the method and devices for implementing the method. The system is implemented by contacting selected mammalian cells (18) with a suitable silver-containing substrate (16) (preferably a substrate containing crystalline silver). Free silver ions from the substrate contact the cells, inducing dedifferentiation of at least a portion of the cells into the unspecialized, embryonic type known as stem cells. These stem cells are believed to be capable of redifferentiating to other selected cell types. |
