The invention discloses a pharmaceutical composition for inhibiting tumor drug resistance and application thereof. The pharmaceutical composition comprises an exosome inhibitor, nintedanib and gemcitabine, the exosome inhibitor, the nintedanib and the gemcitabine are used in a combined manner, so that the cell viability of the CTS can be remarkably reduced, and the proportion of apoptotic cells in the CTS can be remarkably increased; the pharmaceutical composition interferes with the mutual transformation process between normal fibroblasts and CAFs, and inhibits secretion and release of EVs and reduces formation of new CAFs while restoring the CAFs existing in TME to normal fibroblasts, thereby successfully reversing the drug resistance of tumors.

This invention discloses the application of a polysaccharide coating membrane in the preparation of cell culture products, belonging to the field of cell culture food technology. Specifically, after cells are seeded onto a scaffold, a polysaccharide coating membrane is formed around it. This can alleviate the phenomenon of cells detaching from the scaffold during culture, thereby ensuring the effective proliferation and differentiation of muscle stem cells and / or adipose stem cells on the scaffold, providing a new solution for the efficient and standardized production of cell culture products.
