GFP expression in the quiescent liver of adult nestin-GFP transgenic mice. Cell nuclei are stained with DAPI (blue).
A – General view of quiescent nestin-GFP mouse liver. Few GFP-positive cells are seen inside an intralobular bile duct.
B – GFP-positive cells inside a bile duct (arrowhead) and a canal of Hering (arrow).
C – Bile ducts of higher caliber contain a larger number of GFP-positive cells.
Scale bar is 20 μm in A and C, 50 μm in B.
