在本文中,我们探讨了转移性小鼠乳腺癌细胞系 4T1 所表现出的一种非典型的集体细胞迁移形式。我们在此表明​​,在稀疏铺板的 4T1 细胞中,E-钙粘蛋白水平适度降低(约 50%),导致集体迁移的发展,即细胞以松散的簇形式易位,通过薄膜系绳相互连接。敲低E-钙粘蛋白可阻断这些细胞中系链的形成,从而提高迁移率,同时抑制体内肺转移形成,并抑制离体成纤维细胞单层的浸润。这些发现表明,野生型 4T1 细胞中存在的中等 E-钙粘蛋白水平在促进癌症侵袭和转移中发挥着关键作用。
In this article, we explore a non-canonical form of collective cell migration, displayed by the metastatic murine mammary carcinoma cell line 4T1. We show here that in sparsely plated 4T1 cells, E-cadherin levels are moderately reduced (~50%), leading to the development of collective migration, whereby cells translocate in loose clusters, interconnected by thin membrane tethers. Knocking down E-cadherin blocked tether formation in these cells, leading to enhancement of migration rate and, at the same time, to suppression of lung metastases formation in vivo, and inhibition of infiltration into fibroblast monolayers ex vivo. These findings suggest that the moderate E-cadherin levels present in wild-type 4T1 cells play a key role in promoting cancer invasion and metastasis.
