Brand new work from the laboratory of Michel Cayouette, Director of the Cellular Neurobiology Research Unit at the Montreal Clinical Research Institute (IRCM) and Professor in the Faculty of Medicine at the Université de Montréal, published in November in the scientific journal Developmental Cell, reveals for the first time that photoreceptor cells in the mammalian retina exhibit planar polarity, meaning that their light-sensitive cilia orient themselves in a coordinated manner in the plane of the tissue. What’s more, the scientists were able to establish through this work that this polarity is induced by light during a critical period of development, representing a novel mechanism for cellular organization within an animal organism.
