手性力矩驱动下上皮细胞的集体迁移

Collective cell migration of epithelial cells driven by chiral torque generation

Takaki Yamamoto, Tetsuya Hiraiwa, Tatsuo Shibata

摘要:

各种多细胞组织显示手性形态。实验研究表明,这可能源于细胞手性。然而,还没有理论被提出来连接细胞手性扭矩和多细胞手性形态发生。我们提出了一个融合的组织动力学与细胞手征扭矩模型。我们发现,细胞迁移的细胞手性扭矩的梯度下单向。虽然迁移速度取决于组织的机械参数而变化,但它仅由融合组织中液体到固体转变的结构序参量缩放。

英文摘要:

Various multicellular tissues show chiral morphology. Experimental studies have shown this can originate from cell chirality. However, no theory has been proposed to connect the cellular chiral torque and multicellular chiral morphogenesis. We propose a model of confluent tissue dynamics with cellular chiral torque. We found that cells migrate unidirectionally under a gradient of cellular chiral torque. While the migration speed varies depending on the tissue's mechanical parameters, it is scaled solely by a structural order parameter for liquid-to-solid transition in confluent tissues.
