Cardiac differentiation of human embryonic stem cells and their assembly into engineered heart muscle

Curr Protoc Cell Biol. 2012 Jun:Chapter 23:Unit23.8. doi: 10.1002/0471143030.cb2308s55.

Abstract

The advent of pluripotent human embryonic stem cells has created the unique opportunity for the development of a wide variety of humanized cellular tools for basic research, as well as industrial and clinical applications. It has, however, become apparent that embryonic stem cell derivatives in classical monolayer or embryoid body culture do not resemble bona fide tissues, mainly because of their limited organotypic organization and maturation in these culture formats. This shortcoming may be addressed by tissue engineering technologies aiming at the provision of a "natural" growth environment to facilitate organotypic tissue assembly. In this unit, we provide two harmonized basic protocols for (1) cardiac differentiation of human embryonic stem cells under serum-free conditions and (2) the assembly of the stem cell-derived cardiomyocytes into engineered heart muscle. This protocol can be easily adapted to bioengineer heart muscle also from other stem cell-derived cardiomyocytes, including cardiomyocytes from human-induced pluripotent stem cells.
