Fig. 5. Forced activation of Notch signaling by CNIC
C89
transfection. Stage 28 PV were transfected with indicated expression vectors
and cultured for 72 hours. Control explants transfected with EGFP
form simple glands and express differentiation markers (A-C). Transfection of
CNIC
C89 inhibits gland formation and expression of
differentiation-marker genes (D-F). More than 100 explants and more than 40
sections from each explant were investigated. Successfully transfected
epithelial cells never expressed differentiation marker genes. Scale bar: 100
µm.
