THE UPTAKE OF NA-22 DURING INDUCTION IN PRESUMPTIVE EPIDERMIS CELLS OF THE RANA PIPIENS GASTRULA

1. The process of induction after sucrose treatment is accompanied by an increased uptake of Na22 as compared with the uptake by untreated controls.2. The process of induction by lithium chloride treatment results in an increased uptake of Na22 during the lithium treatment.3. The process of induction after lithium treatment is accompanied by an increased uptake of Na22 as compared with untreated controls.
