Cutaneous stem cells (CSCs) orchestrate the homeostasis and regeneration of mammalian skin. Epithelial CSCs have been isolated and characterized from the skin and hold great potential for tissue engineering and clinical applications. The actin cytoskeleton is known to regulate cell adhesion and motility through its intricate participation in signal transduction and structural modifications. The dynamics of actin cytoskeleton can directly influence CSCs behaviors including tissue morphogenesis, homeostasis, niche maintenance, activation, and wound repair. Various regulators of the actin cytoskeleton including kinases, actin-remodeling proteins, paracrine signals, and micro-RNAs collaborate and contribute to epithelial CSC proliferation, adhesion, and differentiation. This review brings together the latest mechanistic insights into how the actin cytoskeleton participates in the regulation of epithelial CSCs during development, homeostasis, and wound repair.
