Abstract: Provided are polymers, which may be crosslinked to form a main-chain liquid crystalline (LC) hydrogel with a three-dimensional network. Also provided are methods of using the hydrogel as a substrate for tissue culture. For example, the hydrogel may organize into LC phases and encapsulate a plurality of cells within its polymeric network. In some embodiments, human stem cells are cultured using the present method with good viability and demonstrate faster proliferation in the present LC hydrogel compared to a non-LC gel.

Abstract: A method for producing a cholesteric liquid crystal layer is a method that can produce a cholesteric liquid crystal layer whose reflection surface is not parallel to a substrate surface by a simple method. The method includes: a step 1 of forming a composition layer satisfying a condition 1, a condition 2, or a condition 3 on a substrate, using a liquid crystal composition including a liquid crystal compound; and a step 2 of subjecting the composition layer to a treatment for cholesterically aligning the liquid crystal compound in the composition layer to form a cholesteric liquid crystal layer.
