This process, called chemotaxis, is seen in present day crustaceans like spiny lobsters, which also line up in an antennae-to-tail procession as they migrate.

Fibrosis was prevented despite preserved recruitment of inflammatory cells and fibroblast chemotaxis.

Upon the basis of a careful diagnosis, the necessary nutritive salts or cell-foods, carefully compounded in accordance with the law of chemotaxis must be administered.
