A method of screening for a therapeutic and/or preventive drug for cartilaginous hyperplasia and a therapeutic and/or preventive drug for cartilaginous hyperplasia are provided. The following are provided: a method of screening for a therapeutic and/or preventive drug for cartilaginous hyperplasia, comprising a step of culturing chondroprogenitor cells under conditions in which the cells are brought into contact with a test substance and conditions in which the cells are not brought into contact with the test substance and a step of determining the SOX9 promoter activity, cAMP level, or degree of phosphorylation of CREB in the cells or the extracellular matrix volume in a culture; and a therapeutic and/or preventive drug for cartilaginous hyperplasia, comprising as an active ingredient an adenylate cyclase inhibitor.

A method for inducing the differentiation of pluripotent stem cells into skeletal muscle or skeletal muscle progenitor cells is provided. Specifically, a method for producing artificial skeletal muscle or skeletal muscle progenitor cells from human pluripotent stem cells is provided, comprising the following steps of: (1) culturing human pluripotent stem cells by suspension culture; (2) culturing a cell population after suspension culture by adhesion culture; (3) dissociating cells after adhesion culture; and (4) culturing the dissociated cells by adhesion culture. Artificial skeletal muscle or induced skeletal muscle progenitor cells prepared by the method are also provided.

The present invention provides a method for inducing differentiation of pluripotent stem cells into mesodermal cells, comprising the step of culturing pluripotent stem cells in a serum-free medium without forming an embryoid body and without coculturing with cells from a different species.
