Stromal cells originated from bone marrow-derived cells in two small intestinal tumors.

<p>GFP(+) BMDCs indicated by white arrows were observed in the stromal tissues of two small intestinal tumors in the GFP direct-fluorescence assay (left panel). The histological images were further displayed with the H&E staining (right panel). H&E-staining images of paraffin-embedded tissue from the intestinal tumor used in this direct-GFP confocal analysis are displayed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0079615#pone.0079615.s003" target="_blank">Figure S3</a>.
