Current cancer drug targets 2023Malignant pleural mesothelioma is a pathology with no effective therapy and a poor prognosis. Our previous study demonstrated an in vitro inhibitory effect on mesothelioma cell lines of both the lysate and secretome of adipose tissue-derived Mesenchymal Stromal Cells. The inhibitory activity on tumor growth has been demonstrated also in vivo: five million Mesenchymal Stromal Cells, injected "in situ", produced a significant therapeutic efficacy against MSTO-211H xenograft equivalent to that observed after the systemic administration of paclitaxel. The objective of this study is to evaluate the efficacy of low amount (half a million) Mesenchymal Stromal Cells and micro-fragmented adipose tissues (the biological tissue from which the Mesenchymal Stromal Cells were isolated) on mesothelioma cells growth. Tumor cells growth inhibition was evaluated in vitro and in a xenograft model of mesothelioma. The inhibitory effect of micro-fragmented fat from adipose-tissue has been firstly confirmed in vitro on MSTO-211H cell growth. Then the efficacy against the growth of mesothelioma xenografts in mice of both micro-fragmented fat and low amount of Mesenchymal Stromal Cells has been evaluated. Our results confirmed that both Mesenchymal Stromal Cells and micro-fragmented fat, injected "in situ", did not stimulate mesothelioma cell growth. By contrast, micro-fragmented fat produced a significant inhibition of tumor growth and progression, comparable to that observed by the treatment with paclitaxel. Low amount of Mesenchymal Stromal Cells exerted only a little anticancer activity. Micro-fragmented fat inhibited mesothelioma cell proliferation in vitro and exerted a significant control of the mesothelioma xenograft growth in vivo.
