Abstract

The invention discloses a rapid extraction method of fibroblast. The method comprises the following steps that 1, isolated tumor tissue is taken and cut into pieces, and a collagenase solution is added for digestion; 2, the mixture is transferred into a centrifugal tube for oscillation, incubation and centrifuging, and sediments are taken to be placed into a cell incubator for culture; 3, the collagenase solution is added for digestion, and the step 2 is executed again to obtain tumor tissue of the loose organization structure obtained after alternate digestion and culture; 4, a pancreatin solution is added, fetal cattle serum is added after normal temperature standing for terminating digestion, suspended solids are poured away, and attaching-wall tumor single cells obtained after trypsin digestion are obtained; 5, a DMEM complete medium is added for subculture, tumor-associated fibroblast is obtained. The invention further provides application of the extraction method. The fibroblast obtained through the extraction method is high in purity, the fibroblast highly expresses FAP, the expression rate is 99.2%, and the method is suitable for medicine popularization.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to a rapid extraction method and application of fibroblasts. Background technique [0002] Cancer-associated fibroblasts (CAFs) are the most important cellular components in the tumor stroma and play a crucial role in the occurrence and development of tumors. CAF can recruit endothelial progenitor cells to local tumors to promote tumor angiogenesis and tumor growth. In addition to expressing vimentin, a marker of fibroblasts, these tumor-associated fibroblasts also specifically express FAP and α-SMA, but not CK and desmin. At the genetic level, it is significantly different from normal fibroblasts (NF). [0003] Tumor-associated fibroblasts are currently one of the research hotspots, and many mechanisms are still controversial, but it is generally believed that the cells are inseparable from the occurrence, development, metastasis and invasion of tumors. Tumor-associated fi...
