Cell signaling has been most extensively studied in the context of human diseases and signaling between cells of a single organism. However, cell signaling may also occur between the cells of two different organisms.In many mammals, early embryo cells exchange signals with cells of the uterus.In the human gastrointestinal tract, bacteria exchange signals with each other and with human epithelial and immune system cells.ell signaling has been most extensively studied in the context of human diseases and signaling between cells of a single organism.
