Cytochemical demonstrations of 5'-nucleotidase and alkaline phosphatase reveal the activity of these enzymes on regions of cell apposition from the late four-cell stage onward. These enzyme activities also appear on regions of artificial cell contact between aggregated embryos having more than four cells. Cytochemistry of single two-cell embryos does not reveal 5'-nucleotidase nor alkaline phosphatase activity, however, these enzyme activities appear at both the artificial and natural contacts in chimaeras of two two-cell embryos. We interpret these results as meaning: (1) that cell contact causes the regionalization of 5'-nucleotidase and alkaline phosphatase activity on the cell surface, (2) that these enzyme activities can be induced or enhanced by contact between two two-cell embryos, (3) that a signal is transmitted from the artificial to the natural contact.
