人类细胞严格控制其尺寸,但在某些癌症中,正常的细胞尺寸控制丧失。在这项研究中,我们测量上皮细胞的细胞体积从人肺腺癌的进展原位。通过利用人工智能(AI),我们在三维(3D)中重建了肿瘤细胞的形状,发现气道2型细胞的体积增加了10倍。令人惊讶的是,细胞大小的增加不是由倍性改变引起的,高达80%的近整倍体肿瘤细胞显示出异常的大小。大小调节异常不能用细胞肿胀或衰老来解释,因为细胞维持细胞质密度和适当的细胞器大小缩放,但与组织组织的变化和似乎连接肺泡2型细胞的新过程网络的丢失相关。为了验证近整倍体细胞中的大小失调,我们根据大小从肿瘤单细胞悬浮液中分选细胞。我们的研究为人类癌症中细胞体积失调提供了前所未有的详细数据。广义上讲,大小控制的丧失可能是人类和小鼠肺腺癌的共同特征,与疾病相关,这些细胞的鉴定为研究细胞大小控制和细胞大小失调的后果提供了有用的模型。
Human cells tightly control their dimensions, but in some cancers, normal cell size control is lost. In this study we measure cell volumes of epithelial cells from human lung adenocarcinoma progression in situ. By leveraging artificial intelligence (AI), we reconstruct tumor cell shapes in three dimensions (3D) and find airway type 2 cells display up to 10-fold increases in volume. Surprisingly, cell size increase is not caused by altered ploidy, and up to 80% of near-euploid tumor cells show abnormal sizes. Size dysregulation is not explained by cell swelling or senescence because cells maintain cytoplasmic density and proper organelle size scaling, but is correlated with changes in tissue organization and loss of a novel network of processes that appear to connect alveolar type 2 cells. To validate size dysregulation in near-euploid cells, we sorted cells from tumor single-cell suspensions on the basis of size. Our study provides data of unprecedented detail for cell volume dysregulation in a human cancer. Broadly, loss of size control may be a common feature of lung adenocarcinomas in humans and mice that is relevant to disease and identification of these cells provides a useful model for investigating cell size control and consequences of cell size dysregulation.
