After being induced to differentiate in vitro, cells with various morphologies showed β-gal activity, including nerve cells, neuroglial cells, epithelial cells. We also detected β-gal activity in a wide variety of tissue elements in solid tumors made by injecting the MC15 and MA34 cells into syngenic mice. Then we produced chimeric embryos by injecting the MC15 cells into Kunming blastocysts and recovering the embryos at various developmental stages.
