20210284970 · 2021-09-16 ·

A method for culturing colorectal cancer solid tumor primary cells and colorectal cancer ascites primary tumor cells and supporting reagents. A method for culturing colorectal cancer solid tumor primary cells and colorectal cancer ascites primary tumor cells and supporting reagents. Colorectal cancer solid tumor tissues are treated with mild cell dissociation reagents, and colorectal cancer cells are isolated from ascites with a mild method, thereby ensuring the vitality of cancer cells to the greatest extent. A special serum-free medium is prepared, and colorectal cancer solid tumor-derived tumor cells are cultured in vitro with a suspension culture system to ensure normal expansion of the cancer cells while eliminating the interference of normal cells to the greatest extent. The colorectal cancer primary cell culture obtained by the method are usable for in vitro experiments, second-generation sequencing, building of animal models, and building of cell lines at multiple cell levels.

Presaturation of supercritical CO.SUB.2 .with water for decellularization of matrices

Decellularization methods for tissue are provided. The method can include: exposing a tissue to a water-saturated, supercritical CO.sub.2. The method can further comprise, prior to exposing the tissue to the water-saturated, supercritical CO.sub.2, saturating a stream of supercritical CO.sub.2. The tissue can be exposed to the water-saturated, supercritical CO.sub.2 at a treatment temperature of about 35° C. to about 40° C. (e.g., about 37° C.). In one embodiment, the water-saturated, supercritical CO.sub.2 is completely saturated with water at the treatment temperature. The tissue can be exposed to the water-saturated, supercritical CO.sub.2 at a constant flow rate, such as less than 3 mL/min (e.g., about 0.5 mL/min to about 2.5 mL/min).
