Abstract

The interaction between the cell and the substrate is the most prominent feature affecting the migration of a crawling cell. This paper proposes a three-dimensional dynamic model using the diffuse interface description that reveals the effects of the interaction between a single crawling cell and the substrate during chemotactic migration. To illustrate the effects of interaction between the cell and the substrate, we consider the interfacial energy between the coexistent materials. Multiple mechanisms including the interface energy, chemotaxis effect, and diffusion, are addressed by employing a diffuse interface model.

흡착형 세포의 이동에 있어 세포와 바닥면간의 상호작용은 매우 중요한 역할을 한다. 본 논문은 주화성에 의한 흡착형 세포의 이동에 있어 세포와 바닥면과의 상호작용에 따른 영향을 보이기 위해 확산계면모델을 바탕으로 한 3 차원의 입체 모델을 제안한다. 세포와 바닥면간의 영향을 표현하기 위해 세포 주위 물질과의 관계를 고려한 경계에너지를 고려하였다. 본 연구에서 적용한 확산계면모델은 경계에너지, 주화성, 확산성을 모두 고려한 다중 메커니즘 모델로서 흡착형 세포이동의 역학적 특성을 정확히 예측하는데 있어 높은 신뢰성을 보일 것이라 기대된다.
