Abstract

BACKGROUND: Mesenchymal stromal cells (MSCs) are considered an important therapeutic tool in cancer therapy. They possess intrinsic therapeutic potential and can also be in vitro manipulated and engineered to produce therapeutic molecules that can be delivered to the site of diseases, through their capacity to home pathological tissues. We have recently demonstrated that MSCs, upon in vitro priming with anti-cancer drug, become drug-releasing mesenchymal cells (Dr-MCs) able to strongly inhibit cancer cells growth. METHODS: Murine mesenchymal stromal cells were loaded with Paclitaxel (Dr-MCsPTX) according to a standardized procedure and their ability to inhibit the growth of a murine B16 melanoma was verified by in vitro assays. The anti-metastatic activity of Dr-MCsPTX was then studied in mice injected i.v. with B16 melanoma cells that produced lung metastatic nodules. Lung nodules were counted under a dissecting stereomicroscope and metastasis investigated by histological analysis. RESULTS: We found that three i.v. injections of Dr-MCsPTX on day 5, 10 and 15 after tumor injection almost completely abolished B16 lung metastasis. Dr-MCsPTX arrested into lung by interacting with endothelium and migrate toward cancer nodule through a complex mechanism involving primarily mouse lung stromal cells (mL-StCs) and SDF-1/CXCR4/CXCR7 axis. CONCLUSIONS: Our results show for the first time that Dr-MCsPTX are very effective to inhibit lung metastasis formation. Actually, a cure for lung metastasis in humans is mostly unlikely and we do not know whether a therapy combining engineered MSCs and Dr-MCs may work synergistically. However, we think that our approach using Dr-MCs loaded with PTX may represent a new valid and additive therapeutic tool to fight lung metastases and, perhaps, primary lung cancers in human.

  • Co-transplantation of paclitaxel-loaded BM-MSCs and acute lymphoblastic leukemia into immunodeficient nude mice resulted in complete inhibition of tumor formation.

    “The co-transplantation of paclitaxel-loaded BM-MSCs and acute lymphoblastic leukemia into immunodeficient nude mice resulted in the complete inhibition of tumor formation, and the intra-tumoral injection of these drug-loaded MSCs led to a decrease in tumor size.”

    From Mesenchymal Stem/Stromal Cells: Immunomodulatory and Bone Regeneration Potential after Tumor Excision in Osteosarcoma Patients (2023) · cites this paper as [114]

    The Background (page unavailable) reports that prior co-injection and intratumoral injection of paclitaxel-loaded MSCs inhibited tumor growth. It does not specify acute lymphoblastic leukemia, immunodeficient nude mice, or complete prevention of tumor formation. This paper’s own experiment instead concerns B16 melanoma lung metastases in syngeneic mice. (LLM, conf=0.86)

  • The CM of paclitaxel-loaded BM-MSCs inhibited VEGF, a main player in tumor angiogenesis.

    “Specifically, the CM of paclitaxel-loaded BM-MSCs inhibited VEGF, a main player in tumor angiogenesis [109,114].”

    From Mesenchymal Stem/Stromal Cells: Immunomodulatory and Bone Regeneration Potential after Tumor Excision in Osteosarcoma Patients (2023) · cites this paper as [114]

    The Methods section (no page number available) says conditioned medium from paclitaxel-loaded BM-derived mesenchymal cells was tested for inhibition of B16 melanoma-cell proliferation. The Discussion (no page number available) describes paclitaxel as anti-angiogenic, but the paper does not report that the conditioned medium inhibited VEGF (searched: VEGF and conditioned medium). (LLM, conf=0.74)

    Experimental — accuracy not yet measured
  • The CM of paclitaxel-loaded ASCs exhibited a dose-dependent effect on Ewing's sarcoma, prostate cancer, blastoma, neuroblastoma, and acute lymphoblastic leukemia cells.

    “Also, the CM of paclitaxel-loaded ASCs exhibited a dose-dependent effect on Ewing’s sarcoma, prostate cancer, blastoma, neuroblastoma, and acute lymphoblastic leukemia cells.”

    From Mesenchymal Stem/Stromal Cells: Immunomodulatory and Bone Regeneration Potential after Tumor Excision in Osteosarcoma Patients (2023) · cites this paper as [114]

    The Results section reports that conditioned medium from paclitaxel-loaded SR4987 cells inhibited B16 melanoma proliferation in a dose-dependent manner. It does not report that effect for paclitaxel-loaded adipose-derived stromal cells (ASCs) or for the five cancer types listed in the claim. The paper’s Background identifies SR4987 as a bone-marrow-derived cell line; page numbers are unavailable in our copy. (LLM, conf=0.88)

  • The CM of paclitaxel-loaded BM-MSCs completely inhibited the proliferation of prostate cancer, glioblastoma, acute lymphoblastic leukemia, malignant pleural mesothelioma, and multiple myeloma cells.

    “whereas the CM of paclitaxel-loaded BM-MSCs completely inhibited the proliferation of prostate cancer, glioblastoma, acute lymphoblastic leukemia, malignant pleural mesothelioma, and multiple myeloma cells [109,114].”

    From Mesenchymal Stem/Stromal Cells: Immunomodulatory and Bone Regeneration Potential after Tumor Excision in Osteosarcoma Patients (2023) · cites this paper as [114]

    The Results section (page unavailable) says conditioned medium from paclitaxel-loaded, bone-marrow-derived SR4987 cells was tested for antiproliferative activity on MOLT-4 leukemia cells. It does not report complete inhibition of MOLT-4 proliferation, or this conditioned-medium result for prostate cancer, glioblastoma, malignant pleural mesothelioma, or multiple myeloma cells. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Intra-tumoral injection of drug-loaded MSCs led to a decrease in tumor size.

    “The co-transplantation of paclitaxel-loaded BM-MSCs and acute lymphoblastic leukemia into immunodeficient nude mice resulted in the complete inhibition of tumor formation, and the intra-tumoral injection of these drug-loaded MSCs led to a decrease in tumor size.”

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.
