Abstract

Although mesenchymal stem cells (MSCs) are considered to be the cells of origin for most sarcomas, the role of MSCs as a source of tumor stroma is not fully understood in this tumor type. The current study investigated whether MSCs affect the tumor growth and metastatic ability in rat osteosarcoma model. Results from subcutaneous co-implantation of rat osteosarcoma COS1NR cells, established in our laboratory, with rat MSCs isolated from femur bone marrow showed that the incidence of tumor formation and tumor growth rate was higher until 5 weeks compared to COS1NR cell inoculation alone. However, no difference was observed in tumor growth afterwards and in the number of metastatic nodules at 9 weeks (0.75 vs. 1.2). Intravenous MSC injection at weeks 3 and 5 after subcutaneous inoculation of COS1NR cells significantly increased the number of lung nodules in the group with MSC injection compared to the group without MSC injection (17.33 vs. 2.0), while no difference was observed in subcutaneous tumor growth between those groups. Pathway analysis from gene expression profile identified that genes involved in focal adhesion, cytokine-cytokine receptor and extracellular matrix-receptor pathways such as CAMs (ICAM and VCAM)-integrins were highly expressed in MSCs, possibly participating in the tumor progression of osteosarcoma. These results suggest that MSCs could provide a source of microenvironments for osteosarcoma cells, and might enhance the ability of settlement and colonization which lead to early onset of growth and metastasis, possibly through their activated pathways interaction.

  • Intravenous bone marrow mesenchymal stromal cell injection led to stabilization of the initial tumour size, without altering its histological appearance, and significant enhancement of metastatic lung nodules (17.33 ± 8.39 vs. 2.0 ± 2.0, p = 0.03).

    “On the other hand, intravenous BMMSC injection led to stabilization of the initial tumour size, without altering its histological appearance, and significant enhancement of metastatic lung nodules (17.33 ± 8.39 vs. 2.0 ± 2.0, p = 0.03).”
  • All animals in which mesenchymal stromal cells and osteosarcoma cells were co-implanted developed tumour by week 4, compared to those that received only osteosarcoma cells and developed tumour by week 6.

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.
