United KingdomDuring embryonic development, hair follicles form distinct geometric patterns across mammalian species. Researchers from the University of Geneva explored how these patterns arise, challenging the traditional 'expansion-induction' model which suggests placodes inhibit neighboring follicle formation. Instead, they propose a simpler mechanism involving cell migration guided by chemical signals, similar to how white blood cells respond to inflammation. Using a mathematical model, they showed this self-organizing process could replicate the formation of hair follicles in both laboratory mice and spiny mice, suggesting a universal principle behind placode patterning.
