Abstract

The invention discloses a scaffold-free tumor organoid culture medium and a culture method for breast cancer, including N-2, B27, Noggin, penicillin / streptomycin double antibody, EGF, FGF10, Y-27632, A83-01, SB202190, N‑Acetylcysteine, R‑Spondin, Nicotinamide, Wnt3A, KGF, Gentamicin, Heregulin, Fetal Bovine Serum, and DMEM‑F / 12. The culture medium and culture method can help to establish a breast cancer tumor organoid that does not require scaffold materials and can maintain a high degree of tumor specificity, realizes controllable size, regular spherical shape, high success rate, short time, and specific drug sensitivity results high. The culture medium and the culture method of the invention can provide an ideal model for the occurrence and development of mammary gland tumors, in vitro drug sensitivity screening and drug resistance mechanism research.

Description

technical field

[0001] The invention relates to the technical field of cell culture, in particular to a special culture medium and a culture method for breast cancer organoids. Background technique

[0002] Breast cancer is one of the most common malignant tumors in women, and its incidence is increasing year by year. In September 2018, the International Agency for Research on Cancer (IARC), a subsidiary of the WHO, released the "2018 Global Cancer Statistics", and the incidence and mortality of breast cancer both won the first place, making it the number one cancer killer of women in the world. There are 210,000 new cases of breast cancer patients in my country every year, and the growth rate of the incidence rate is twice the global average growth rate, ranking first in the world. In my country, the incidence rate of breast cancer in cities is the second among female malignant tumors. In some big cities, the incidence rate of breast cancer has risen to the first place, an...
