Abstract At present, the demand for meat products has increased because of the rapid growth of the population. The livestock system raises a number of environmental and ethical issues. Therefore, the research of artificial meat will have an important impact on the supply of meat products in the future. Artificial meat includes cultured meat and plant protein meat. Among them, cultured meat is the best alternative to conventional meat. However, large-scale production of cultured meat still faces many challenges due to technical difficulties and high costs. In this review, the development process and current technical challenges of cultured meat are introduced, including the selection of cell types for initial culture, factors and regulatory methods which restrict cell proliferation and differentiation, cell culture environment optimization and muscle tissue formation in vitro. This review provides reference for the industrial production of cultured meat.
