Figure 5. HBE, CBF, hMSC, and HLFs all demonstrate initial proliferation post-inoculation in decellularized normal and emphysematous human lungs by positive Ki67 staining.
Representative photomicrographs of Ki67 (red) or caspase-3 (green) staining are shown at 1 day post-inoculation and at the last viable time point cells were observed in acellular normal (Panel A) or emphysematous lung (Panel B). DAPI nuclear staining is depicted in blue. White arrow indicates positive staining. Original magnification 200x.
