Distinct mechanisms underlie pattern formation in the skin and skin appendages.
Patterns form with the break of homogeneity and lead to the emergence of new structure or arrangement. There are different physiological and pathological mechanisms that lead to the formation of patterns. Here, we first introduce the basics of pattern formation and their possible biological basis. We then discuss different categories of skin patterns and their potential underlying molecular mec...

A nonlinear analysis of a mechanical model for biological pattern formation, SIAM J. pattern selection in a mechanical model for morphogenesis, Mathematical modelling of the generation and onset of spatial patterns in the early stages of embryonic development — reaction-diffusion equations, chemotaxis equations, mechanochemical force balance equations.

متن کاملMechanism of skin morphogenesis. II. Retinoic acid modulates axis orientation and phenotypes of skin appendages.
The factors that determine the axial orientation and phenotypes of skin appendages were analyzed by studying the effect of retinoic acid (RA) on embryonic chicken skin explant cultures. With RA uniformly distributed in the culture media, the feather buds became smaller, were disoriented or were transformed into scale-like structures in a concentration-dependent manner (from 0.05-2.5 microM). Wi...
متن کاملPhysiological regeneration of skin appendages and implications for regenerative medicine.
The concept of regenerative medicine is relatively new, but animals are well known to remake their hair and feathers regularly by normal regenerative physiological processes. Here, we focus on 1) how extrafollicular environments can regulate hair and feather stem cell activities and 2) how different configurations of stem cells can shape organ forms in different body regions to fulfill changing...
متن کاملSequential pattern formation in a model for skin morphogenesis.
During morphogenesis regular patterns often develop behind a frontier of pattern formation which travels across the prospective tissue. Here the authors consider the propagating patterns exhibited in a two-dimensional domain by a tissue interaction mechanochemical model for skin pattern formation. It is shown that the model can exhibit travelling waves of complex spatial pattern formation. Two ...
