Fig. 2. Identification of hepatocytes and endothelial cells in control mice. (A,B)
Liver sections from a chimeric control (A) and a negative control mouse (B)
showing DAPI stained nuclei (blue) and YFP fluorescence (yellow). Scale bar:
50 µm. (C-H) Frozen liver section from a chimeric control mouse showing
hepatic sinusoids: YFP (yellow); CD31 (red); CD45 (purple); DAPI (blue).
YFP+ hepatocytes are outlined with a broken line, arrowheads
highlight two representative YFP+ endothelial cells; arrow shows the position
of one hematopoietic cell close to a vessel. Scale bar: 25 µm. (I-K) Frozen
liver sections from a negative control mouse showing part of a larger hepatic
vessel: autofluorescence (yellow); CD31 (red); CD45 (purple); DAPI (blue). The
position of the autofluorescent basement membrane is indicated by broken
lines. Arrows and arrowheads in I-K indicate the positions of hematopoietic
cells and the endothelial cell layer, respectively. Scale bar: 25 µm.
