Abstract

Chimeric proteins have been used for years for various purposes ranging from biomaterials to candidate drug molecules, and from bench to bulk. Regenerative medicine needs various kinds of proteins for providing essential factors for maintaining starting cells, like induced pluripotent stem cells (iPSC), and renewal, proliferation, targeted differentiation of these cells, and as extracellular matrix for the experimental cells. However, there are several challenges associated with making functional chimeric proteins for effective application as biomaterial in this field. Fc-chimeric protein technology could be an effective solution to overcome many of them. These tailored proteins are recently becoming superior choice of biomaterials in stem cell technology and regenerative medicine due to their specific advantageous biophysical and biochemical properties over other chimeric forms of same proteins. Recent advances in recombinant protein-related science and technology also expedited the popularity of this kind of engineered protein. Over the last decade our lab has been pioneering this field, and we and others have been successfully applied Fc-chimeric proteins to overcome many critical issues in stem cell technologies targeting regenerative medicine and tissue engineering. Fc-chimeric protein-based biomaterials, specifically, E-cad-Fc have been preferentially applied for coating of cell culture plates for establishing xenogeneic-agent free monolayer stem cell culture and their maintenance, enhanced directed differentiation of stem cells to specific lineages, and non-enzymatic on-site one-step purification of target cells. Here the technology, recent discoveries, and future direction related with the E-cad-Fc-chimeric protein in connection with regenerative medicine are described.
