Using embryonic stem cells to form a biological pacemaker via tissue engineering technology.

Biological pacemakers can be achieved by various gene-based and cell-based approaches. Embryonic stem cells (ESCs)-derived pacemaker cells might be the most promising way to form biological pacemakers, but there are challenges as to how to control the differentiation of ESCs and to overcome the neoplasia, proarrhythmia, or immunogenicity resulting from the use of ESCs. As a potential approach to solve these difficult problems, tissue-engineering techniques may provide a precise control on the different cell components of multicellular aggregates and the forming of a construct with-defined architectures and functional properties.
