Directional Cell Migration and Chemotaxis in Wound Healing Response to PDGF-AA are Coordinated by the Primary Cilium in Fibroblasts

Abstract: Cell motility and migration play pivotal roles in numerous physiological and pathophysiological processes including development and tissue repair. Cell migration is regulated through external stimuli such as platelet-derived growth factor-AA (PDGF-AA), a key regulator in directional cell migration during embryonic development and a chemoattractant during postnatal migratory responses including wound healing. We previously showed that PDGFRα signaling is coordinated by the primary cilium in quiescent cells. How… Show more

“…Cilia in the airway, oviduct, embryonic node, and ependyma generate extracellular flows of mucus and other fluids. In adults, these flows are required for proper tissue function-for example, the clearing of mucus from the airway-whereas in developing organisms, these flows provide directional cues for left-right symmetry breaking and cell migration (Sawamoto et al 2006, Marshall and Kintner 2008, Schneider et al 2010, Yoshiba and Hamada 2014. Cilia do not just generate mechanical forces but also sense forces.…”

“…Dans ces modèles cellulaires, le cil contrôle la direction de la migration. Il semble fonctionner comme une antenne sensorielle capable de collecter et de relayer des signaux extracellulaires vers le centrosome et les microtubules [16]. Nous avons recherché si le cil est impliqué dans le contrôle de la polarité des neurones GABAergiques migrateurs.…”

“…L'invalidation du cil primaire altère donc la capacité des neurones GABAergiques à réorienter leur trajectoire (branches neuritiques) pour quitter le flux de migration tangentiel [1]. Ce défaut ressemble à celui des fibroblastes invalidés pour le cil primaire, qui perdent la capacité de se réorienter vers une zone dépourvue de cellules et de la coloniser [16]. Les neurones GABAergiques mutants pour ARL13b (ADP-ribosylation factor-like 13b), une GTPase adressée à la membrane ciliaire, présentent, en plus des défauts de migration décrits ci-dessus, un fort ralentissement de la migration [2].…”

“…The adhesion of cells and tissues to their environment has profound consequences on processes such as cell polarization [1], division, differentiation [2], tissue morphology during development [3], wound healing [4][5][6], and cancer metastasis [7]. Hence, quantifying how cells attach to impart force on the surrounding material is an important technical challenge in cell biology.…”
