Modulation of embryonic stem cell fate and somatic cell reprogramming by small molecules

Artículo

Embryonic stem cells (ESC) are pluripotent cells and have the ability to self-renew in vitro and to differentiate into cells representing all three germ layers. They provide enormous opportunities for basic research, regenerative medicine as well as drug discovery. The mechanisms that govern ESC fate are not completely understood, so a better understanding and control of ESC self-renewal and differentiation are pivotal for therapeutic applications. In contrast to growth factors and genetic manipulations, small molecules offer great advantages in modulating ESC fate. For instance, they could be conveniently identified through high-throughput screening, work across multiple signalling pathways and affect epigenetic modifications as well. This review focuses on the recent progress in the use of small molecules to regulate ESC self-renewal, differentiation and somatic cell reprogramming.
