細(xì)胞形態(tài)的光學(xué)顯微鏡分析提供了細(xì)胞功能和蛋白質(zhì)定位的高內(nèi)涵數(shù)據(jù)。對(duì)培養(yǎng)細(xì)胞的細(xì)胞陣列和微孔轉(zhuǎn)染分析使細(xì)胞表型分析可用于高通量實(shí)驗(yàn)。蛋白質(zhì)組中每種蛋白質(zhì)的定位和單個(gè)基因的 RNAi 敲低對(duì)細(xì)胞形態(tài)的影響都可以通過手動(dòng)檢查顯微圖像來測(cè)定。然而，使用功能基因組學(xué)的形態(tài)讀數(shù)需要快速和自動(dòng)識(shí)別復(fù)雜的細(xì)胞表型。在這里，我們提出了一個(gè)全自動(dòng)平臺(tái)，用于結(jié)合人類活細(xì)胞陣列、篩選顯微鏡和基于機(jī)器學(xué)習(xí)的分類方法進(jìn)行高通量細(xì)胞表型篩選。該平臺(tái)的效率通過對(duì)由 GFP 標(biāo)記的蛋白質(zhì)標(biāo)記的 11 種亞細(xì)胞模式進(jìn)行分類來證明。我們的分類方法幾乎可以適用于任何基于細(xì)胞形態(tài)的顯微分析，從而開啟了廣泛的應(yīng)用，包括人類細(xì)胞中的大規(guī)模 RNAi 篩選。

腫瘤發(fā)生與反復(fù)轉(zhuǎn)移國(guó)際數(shù)據(jù)庫描述：

Light microscopic analysis of cell morphology provides a high-content readout of cell function and protein localization. Cell arrays and microwell transfection assays on cultured cells have made cell phenotype analysis accessible to high-throughput experiments. Both the localization of each protein in the proteome and the effect of RNAi knock-down of individual genes on cell morphology can be assayed by manual inspection of microscopic images. However, the use of morphological readouts for functional genomics requires fast and automatic identification of complex cellular phenotypes. Here, we present a fully automated platform for high-throughput cell phenotype screening combining human live cell arrays, screening microscopy, and machine-learning-based classification methods. Efficiency of this platform is demonstrated by classification of eleven subcellular patterns marked by GFP-tagged proteins. Our classification method can be adapted to virtually any microscopic assay based on cell morphology, opening a wide range of applications including large-scale RNAi screening in human cells.
