Cell migration plays a central role in a wide variety of biological processes, as exemplified in
embryogenesis, inflammatory responses, wound healing, and tissue repair. 1–4 In the case
of tissue repair, for example, the recruitment and migration of desirable cells to the defect
site is key to the construction and regeneration process. For instance, the regeneration of
skin includes re-establishment of the dermis structure, which can be accelerated by
triggering the directional migration of epithelial cells and fibroblasts to the wound area. 2 On …
