Developing engineered muscle tissues utilizing standard cell culture plates and mesenchymal stem cell-conditioned medium

Abstract

The construction of engineered muscle tissues that resemble the function and microstructure of human muscles holds significant promise for various applications, including disease modeling, regenerative medicine, and biological machines. However, current muscle tissue engineering approaches often rely on complex equipment which may limit their accessibility and practicality. Herein, we present a convenient approach using a standard 24-well cell culture plate to construct a platform to facilitate engineered muscle tissues formation and culture. Using this platform, engineered muscle tissue with differentiation characteristics can be manufactured in large quantities. Additionally, the mesenchymal stem cell conditioned medium was utilized to promote the formation and functionality of the engineered muscle tissues. The resulting tissues comprised a higher cell density and a better differentiation effect in the tissues. Taken together, this study provides a simple, convenient, and effective platform for studying muscle tissue engineering.
