Generation of human induced pluripotent stem cells in defined, feeder-free conditions

Abstract

Herein, we describe a modified protocol for the generation of human induced pluripotent stem cells (hiPS) and expansion under defined, serum free and feeder free conditions. These cells exhibit a high level of plasticity towards various differentiation pathways both in vitro and in vivo. Ultimately, hiPS-derived lines achieved high standards of three dimensional differentiations on biomaterial scaffolds and promoted in vivo regeneration of complex organs, such as Anterior Cruciate Ligament (in swine ACL-rupture models) and other tissues as well.
