近10余年来,定量细胞化学的迅速发展,对生物学、医学许多领域的研究起到了有意义的影响。流式细胞术(Flow Cytometry简称FCM)是70年代发展起来的一种对单细胞进行快速定量分析和分选的新技术。对每个细胞可同时测得多个参数,通过在细胞分子水平定量分析核内DNA,使细胞异常的定量诊断成为可能,且灵敏度高,对肿瘤的早期诊断和预后有较大的参考价值。在泌尿系肿瘤的研究中,FCM有许多功用。例如,可协助对前列腺癌针吸活检的细胞学
In the past more than 10 years, the rapid development of quantitative cytochemistry has exerted a significant impact on many fields of biology and medicine. Flow Cytometry (Flow Cytometry) is a new technique developed in the 1970s for rapid quantitative analysis and sorting of single cells. For each cell, multiple parameters can be measured at the same time. Quantitative analysis of nuclear DNA at the molecular level of the cell makes it possible to quantitatively diagnose abnormal cells, and has high sensitivity, which is of great value for early diagnosis and prognosis of tumors. In the study of urinary tumors, FCM has many functions. For example, to assist in the cytology of prostate cancer needle biopsy
