BioArtificial Hydrogels and Mechanobiology Technologies for Regenerative Medicine 

Cell adhesion to extracellular matrices plays central roles in the formation, maintenance and repair of numerous tissues. Cell adhesion to extracellular matrix proteins is primarily mediated by the integrin family of adhesion receptors. We have established biomolecular strategies for the engineering of bioartificial materials to direct integrin binding specificity and signaling as well as technologies to study and control mechanobiology responses. These materials regulate cell adhesion and signaling to direct in vitro cell function (adhesion, proliferation, and differentiation) and in vivo healing responses for tissue repair and integration. We have engineered a modular synthetic hydrogel platform for controlled presentation/delivery of adhesive ligands, therapeutic proteins, and degradable cross-links. For example, we have synthesized synthetic hydrogels presenting defined densities of adhesive ligands, vasculogenic growth factors, and protease degradable sequences that direct therapeutic vascularization and cell engraftment. We have also used photo-triggerable peptides to control cellular responses with respect to time and space. These approaches provide a basis for the rational design of robust bioinstructive materials that tailor adhesive interactions and elicit specific cellular responses for the development of 3D hybrid scaffolds for enhanced tissue reconstruction, “smart” biomaterials, and cell growth supports.  

Short Bio:

Andrés J. García is the Rae S. and Frank H. Neely Endowed Chair and Regent’s Professor in the Woodruff School of Mechanical Engineering and the Petit Institute for Bioengineering and Bioscience at the Georgia Institute of Technology. He received a B.S. in Mechanical Engineering with Honors from Cornell University in 1991. He received M.S.E. (1992) and Ph.D. (1996) degrees in Bioengineering from the University of Pennsylvania. He completed a two-year post-doctoral fellowship in cell and molecular biology at the School of Medicine of the University of Pennsylvania. Dr. García’s research program centers on integrating innovative engineering, materials science, and cell biology concepts and technologies to generate (i) novel insights into the regulation of adhesive forces and 001mechanotransduction, and (ii) cell-instructive materials for tissue repair in regenerative medicine applications. His research has received funding from the NIH, NSF, Coulter Foundation, Arthritis Foundation and Juvenile Diabetes Research Foundation. He has received several distinctions, including the NSF CAREER Award, Arthritis Investigator Award, Georgia Tech’s CETL/BP Junior Faculty Teaching Excellence Award, Young Investigator Award from the Society for Biomaterials, Georgia Tech’s Outstanding Interdisciplinary Activities Award, and the Clemson Award for Basic Science from the Society for Biomaterials. He serves on the editorial board of leading biomaterial and regenerative medicine journals. He has been recognized as a top Latino educator by the Society of Hispanic Professional Engineers. He has been elected a Fellow of Biomaterials Science and Engineering by the International Union of Societies of Biomaterials Science and Engineering, AIMBE, and AAAS.
