    • An automated method of screening for cervical cancer cells, comprising the steps of:
      (a) obtaining a slide containing a fluid biological sample comprising nuclei from a subject, said biological sample having been contacted with a first nuclear centromeric probe bearing a first detectable label directed either to chromosome 3 or chromosome 7, and a second nuclear non-centromeric probe bearing a second detectable label directed to single copy sequences on the q arm of chromosome 3 wherein said single copy sequences comprise a contiguous sequence of four overlapping BAC clones containing at least a portion of the TERC gene at chromosomal location 3q26, and counterstained with DAPI, wherein said first and second probes are contacted under conditions that promote hybridization of each said first and second probe to the respective chromosomal loci;
      (b) searching said slide for DAPI stained areas within said biological sample;
      (c) searching said DAPI stained areas for the presence of label of said first nuclear centromeric probe and label of said second nuclear non-centromeric probe;
      (d) quantitatively determining the number of said first nuclear centromeric probe and second nuclear non-centromeric probe per nucleus in each DAPI stained area within said biological sample;
      (e) designating the biological sample as comprising a potential for progression to high hyperplasia and invasive cervical cancer when the number of said first probe per nucleus within the DAPI is about 2 per nucleus and the number of said second nuclear non-centromeric probe per nucleus within the DAPI stained area is equal to or greater than 4.
    • 一种筛选宫颈癌细胞的自动化方法,包括以下步骤:(a)获得包含含有来自受试者的核的流体生物样品的载玻片,所述生物样品已经与带有第一可检测标记的第一核着丝粒探针接触 或者染色体3或染色体7,以及携带针对染色体3的q臂上的单拷贝序列的第二可检测标记的第二核非着丝粒探针,其中所述单拷贝序列包含至少含有四个重叠BAC克隆的连续序列 在染色体位置3q26处的TERC基因的一部分,并用DAPI复染色,其中所述第一和第二探针在促进每个所述第一和第二探针与相应染色体基因座杂交的条件下接触; (b)在所述生物样品中搜索所述载玻片上的DAPI染色区域; (c)搜索所述DAPI染色区域存在所述第一核着丝粒探针的标记和所述第二核非着丝粒探针的标记; (d)定量测定所述生物样品中每个DAPI染色区域中每个核的所述第一核着丝粒探针和第二核无着丝粒探针的数目; (e)当DAPI内的每个核上的所述第一个探针的数量为每个细胞核约2个,每个细胞核的所述第二个核非着丝粒探针的数目为多个时,指定生物样品包括进展为高增生和侵袭性宫颈癌的可能性 在DAPI染色区域内等于或大于4。
