NK细胞囊泡/外泌体体外杀伤肿瘤细胞的实验数据集

一、 NK细胞囊泡/外泌体的获取与制备：分离、纯化获得足量的NK囊泡（NK-EVs)和NK外泌体（NK-EXOs）。
二、 NK细胞囊泡/外泌体体外杀肿瘤活性评价：以肿瘤细胞为靶细胞，将不同浓度梯度的NK外泌体与靶细胞共培养，建立“外泌体-肿瘤细胞”作用体系。在特定条件孵育后，使用CCK-8法检测细胞活力，测定各孔在450 nm处的吸光度值。
三、 数据处理与分析：根据测定的吸光度值，应用细胞毒性计算公式：细胞毒性（%） = [1 - (实验组OD值 -空白组OD值) / 对照组OD值] × 100%
计算出不同浓度NK囊泡/外泌体对肿瘤细胞的杀伤率。最终构建NK囊泡/外泌体体外杀肿瘤活性数据集，涵盖囊泡/外泌体来源、肿瘤细胞类型、作用浓度、作用时间、杀伤率等关键参数。

1. Isolation and Preparation of NK Cell-Derived Vesicles/Exosomes: Isolate and purify sufficient quantities of NK cell-derived vesicles (NK-EVs) and NK cell-derived exosomes (NK-EXOs).
2. In Vitro Tumor-Killing Activity Evaluation of NK Cell-Derived Vesicles/Exosomes: Using tumor cells as target cells, co-culture target cells with NK exosomes across a concentration gradient to establish an "exosome-tumor cell" interaction system. After incubation under specified conditions, detect cell viability using the CCK-8 assay, and measure the absorbance of each well at 450 nm.
3. Data Processing and Analysis: Based on the measured absorbance values, apply the following cytotoxicity calculation formula: Cytotoxicity (%) = [1 - (OD value of experimental group - OD value of blank group) / OD value of control group] × 100% to calculate the tumor cell killing rate of NK cell-derived vesicles/exosomes at different concentrations. Finally, construct an in vitro tumor-killing activity dataset of NK cell-derived vesicles/exosomes, which covers key parameters including vesicle/exosome source, tumor cell type, treatment concentration, incubation duration, and killing rate.
