细胞增殖检测是用于测量细胞总数、增殖速率或代谢活性的技术。常见方法包括细胞计数、细胞增殖标记、MTT（3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑）分析等。这些技术用于研究细胞生长、药物筛选、毒性评估以及肿瘤细胞的恶性转化等。通过定量细胞增殖，科学家可以评估生物学过程、疾病发展和药物效应，为生物医学研究提供重要数据。

Cell proliferation assays are techniques used to measure total cell count, proliferation rate, or metabolic activity. Common methods include cell counting, cell proliferation labeling, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazole) analysis, etc. These technologies are used to study cell growth, drug screening, toxicity assessment, and malignant transformation of tumor cells. By quantifying cell proliferation, scientists can assess biological processes, disease development, and drug effects, providing important data for biomedical research.
