Gap junctions allow the exchange of many types of cytoplasmic materials between adjacent cells. How do assemblages of cellslinked by gap junctions-freely exchanging ions, amino acids,sugars, and nucleotides-challenge the concept of cells? What is the functional difference between a single cell, a series of cellslinked by gap junctions, and a tissue?
