Nematic liquid crystals formed by living amoeboid cells

cells have the ability to form liquid crystal phases: (i) A cluster a polar nematic liquid crystal is formed by cells which emit molecules for other cells and (ii) an apolar nematic liquid crystal is formed by cells which have an anisotropic steric repulsion. The angle function is predicted by using the characteristics of an automatic where the extracellular guiding field is approximated by-dimensional mean-field. The nematic liquid crystal state is quite well by the model.
