Methyl cellulose is a nonionic cellulose ether with unique thermogelling properties and no toxicity[1]. Methyl cellulose is a synthetic, water-soluble polymer composed of many linked glucose molecules used as a stabilizer, thickener and emulsifier in food and cosmetics[2]. Methyl cellulose can be used to prepare semisolid matrices as cell culture gels for culturing colony-forming cells[3, 4]. Methyl cellulose can be used as a glycerol substitute in cryopreservation media and together with culture supplements to enhance the proliferation and differentiation of multilineage or monolineage committed hematopoietic progenitor cells[5]. It is difficult to prepare a solution of Methyl cellulose in cold water; when the powder comes into contact with water, it forms a gel layer around it, which helps to accelerate dissolution under heated stirring conditions[6].

Methyl cellulose是一种非离子纤维素醚，具有独特的热胶凝性质，没有毒性[1]。Methyl cellulose是一种合成的水溶性聚合物，由许多连接的葡萄糖分子组成，用作食品和化妆品的稳定剂、增稠剂和乳化剂[2]。Methyl cellulose能够用于制备半固体基质，作为细胞培养凝胶，用于培养集落形成细胞[3, 4]。Methyl cellulose能够在冻存培养基中用作甘油的替代品，与培养补充剂一起使用，以增强多系或单系定型造血祖细胞的增殖和分化[5]。用冷水制备Methyl cellulose溶液是很困难的，当粉末与水接触时，它会在其周围形成凝胶层，在加热搅拌条件下有助于加速溶解[6]。
