Mesenchymal Stem Cell Targeting of Microscopic Tumors and Tumor Stroma Development Monitored by Noninvasive In vivo Positron Emission Tomography Imaging
Open accessAbstract
The aim of this study was to assess the efficacy human mesenchymal stem cells (hMSC) for targeting microscopic tumors and suicide gene or cytokine gene therapy. Immunodeficient mice were transplanted s.c. with human colon cancer cells of HT-29 Inv2 or CCS line, and 3 to 4 days later, i.v. with “tracer” hMSCs expressing herpes simplex virus type 1 thymidine kinase (HSV1-TK) and enhanced green fluorescent protein (EGFP) reporter genes. Subsequently, these tumors were examined for specificity and magnitude of HSV1-TK+, EGFP+ stem cell engraftment and proliferation in tumor stroma by in vivo positron emission tomography (PET) with 18F-labeled 9-(4-fluoro-3-hydroxymethylbutyl)-guanine ([18F]-FHBG). In vivo PET images of tumors growing for 4 weeks showed the presence of HSV1-TK+ tumor stroma with an average of 0.36 ± 0.24% ID/g [18F]-FHBG accumulation. In vivo imaging results were validated by in situ correlative histochemical, immunofluorescent, and cytometric analyses, which revealed EGFP expression in vWF+ and CD31+ endothelial cells of capillaries and larger blood vessels, in germinal layer of dermis and hair follicles proximal to the s.c. tumor site. These differentiated HSV1-TK+, GFP+ endothelial cells had limited proliferative capacity and a short life span of <2 weeks in tumor fragments transplanted into secondary hosts. We conclude that hMSCs can target microscopic tumors, subsequently proliferate and differentiate, and contribute to formation of a significant portion of tumor stroma. PET imaging should facilitate clinical translation of stem cell–based anticancer gene therapeutic approaches by providing the means for in vivo noninvasive whole-body monitoring of trafficking, tumor targeting, and proliferation of HSV1-tk-expressing “tracer” hMSCs in tumor stroma.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
