Abstract

Stem cells have the potential to be differentiated to a specific cell type through genetic manipulation and therefore, represent a new and versatile source of cell replacement in regenerative medicine. However, conventional ways of gene transfer to these progenitor cells, suffer from a number of disadvantages particularly involving safety and efficacy issues. We have recently reported on the development of a bio-functionalized DNA carrier of carbonate apatite by embedding fibronectin and E-cadherin chimera on the carrier, leading to its high-affinity interactions with embryonic stem cell surface and accelerated transgene delivery for subsequent expression. Here, we show the molecular basis of synthesizing highly functional composite particles utilizing DNA, cell-adhesive proteins and inorganic crystals, and finally establish a superior transfection system for a mouse stem cell line having potential applications in cell-based therapy.
