Abstract

Molecular analyses of hair follicle formation provide evidence to support the most well-known mathematical model for biological pattern formation.

None
Biological pattern formation
Two mechanisms can show similar results. (Left) Outcome of a reaction-diffusion model (7) in which activator and inhibitor react and diffuse. Small random fluctuations in the initial field lead to coinciding spatial patterns of activator and inhibitor concentration. (Right) Results of a cell chemotaxis model (9) in which cells and chemical both diffuse, with cells also moving up gradients in chemical concentration. Again, small random fluctuations in the initial field lead to coinciding spatial patterns in cell density and chemical concentration. Blue indicates low concentration levels; red indicates high levels.
