A, Constitutive Notch1 activation induces focus formation in NIC-infected melanocytes grown in monolayer on tissue culture dishes. *p<0.005 (Student's T-test).
B, NIC-infected melanocytes display increased survival in limiting growth factor conditions, as depicted. 100% media indicates normal melanocytes media containing bFGF, SCF, and ET3. 10% media is a 10-fold decrease in FBS; the growth factor(s) present in each respective medium is described beneath each panel. *p<0.005 (Student's T-test).
C, NIC-infected melanocytes display anchorage-independent growth in soft agar. *p<0.005 (Student's T-test).
