Immunofluorescence for human vimentin and cytokeratin after transplantation.

<p>The harvested tissues were detected by dual immunofluorescence for human vimentin and cytokeratin 28 days after transplantation. Stromal cells were specifically stained with vimentin (green), while epithelial cells were specifically stained with cytokeratin (red). Nuclei were visualized by DAPI (blue). Bars: 100 µm. Figure is from serial thin sections. Original magnification: 400×.
