Embodiment 2

[0148] Example 2. Obtaining of postoperative specimens / biopsy puncture specimens / pleural and ascites samples of gynecological tumors

[0149] 1. Cooperate with tertiary hospitals, and the cooperation has passed the formal medical ethics review.

[0150] 2. The attending doctor selects the patients according to the clinical indications stipulated in the medical guidelines, and selects appropriate samples for in vitro culture according to the clinical indications during the operation. The selection criteria of the samples are: primary breast cancer, ovarian cancer, uterine Endometrial cancer, cervical cancer or its metastatic lesions, surgical specimens weighing more than 20mg, or pleural and ascites samples exceeding 100mL, or needle biopsy specimens exceeding 4 samples.

[0151]3. The attending doctor provides basic clinical information such as the patient's gender, age, medical history, family history, smoking history, pathological staging and typing, and clinical diagnosis. ...

Embodiment 3

[0153] Example 3, Gynecological Tumor Solid Tumor Tissue Sample Dissociation Pretreatment

[0154] The following operations need to be performed on ice, and the entire operation steps need to be completed within 10 minutes.

[0155] The surgical equipment used in the following operations must be sterilized by high temperature and high pressure before use.

[0156] 1. Sample weighing.

[0157] 2. Clean the surface of the sample with 75% (volume percent) ethanol for 10 to 30 seconds.

[0158] 3. Wash the sample 5 times with sample cleaning solution, and wash the sample 5 times with sterile PBS solution.

[0159] 4. Use ophthalmic scissors, ophthalmic forceps, scalpel and other equipment to carefully peel off the adipose tissue, connective tissue, and necrotic tissue in the sample.

Abstract

The invention discloses a culture medium for culturing primary cells of gynecological tumors. The culture medium for culturing the primary cells of the gynecological tumors is a special serum-free culture medium, and the culture medium is used for carrying out in-vitro suspension culture on solid tumor cells from the gynecological tumors, so that the interference of normal cells can be eliminatedto the maximum extent while the tumor cells normally amplify. A culture of the primary cells of the gynecological tumors, which are obtained by utilizing the method disclosed by the invention, can beused for in-vitro experiments at various cell levels, second-generation sequencing, animal model construction, cell line construction and the like. Foreseeably, the culture method has a wide application prospect in the fields of research and clinical diagnosis and treatment of the gynecological tumors.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a culture medium for cultivating primary cells of gynecological tumors. Background technique [0002] Common gynecological tumors include breast cancer, ovarian cancer, and endometrial cancer. According to the statistics of the National Cancer Center in 2018, in 2014, breast cancer accounted for 16.5% of the incidence of female malignant tumors in my country, and the mortality rate reached 7.8%, ranking first and fifth among female tumors respectively. At present, the 5-year survival rate of breast cancer in my country is only 73.1% vs 90% (USA), which is still far behind developed countries. In addition, the incidence of ovarian cancer in my country accounts for 2.5% of female malignant tumors, and has increased by 30% in the past ten years. These gynecological tumors pose a severe challenge to the lives and health of women in my country. [0003] Although scientific research and...
