WebNov 26, 2024 · In the clock and gradient model (C&G), the wavefront is formed by a FGF gradient that progressively regresses toward the tail. Cells synchronize their clocks in a way that they form a stripe of gene expression that sweeps from tail to head. The gradient specifies the position at which the clock slows down and triggers the segmentation … qvc electric patio heaterWebDifferences are then made explicit between the many 'clock and wavefront' model variants that have been proposed to explain how the clock regulates segmentation. An understanding of the somitogenesis clock will require addressing experimentally the many questions that arise from the study of simple models. shiseido refining makeup primer reviewsWebSeveral models of somitogenesis have been put forward.
