Milica Radisic (Serbian: Милица Радишић/Milica Radišić; born 1976) is a Serbian Canadian tissue engineer, academic and researcher. She is a professor at the University of Toronto’s Institute of Biomaterials and Biomedical Engineering, and the Department of Chemical Engineering and Applied Chemistry. She co-founded TARA Biosystems[3] and is a senior scientist at the Toronto General Hospital Research Institute.[4]
Radisic is known for creating beating heart tissue in a dish using human-induced pluripotent stem cells. Her research has led the replication of diseased human heart tissue that can be used for drug screening to help create treatment therapies for patients with heart injury.[5]
Radisic attended the University of Novi Sad for her freshman year and transferred to McMaster University in 1996. She graduated with a bachelor's degree in chemical engineering in 1999 and earned her Ph.D. in chemical engineering from Massachusetts Institute of Technology in 2004. She then completed a postdoctoral fellowship at Harvard-MIT Division of Health Sciences and Technology in 2005.[12]
Career
Radisic started her career as a research assistant at McMaster University and MIT before working as a postdoctoral associate at Harvard-MIT Division of Health Science and Technology. In 2005, Radisic joined Institute of Biomaterials and Biomedical Engineering at the University of Toronto as an assistant professor at the Department of Chemical Engineering and Applied Chemistry.[12] She was promoted to associate professor in 2010 and to professor, in 2014.[4]
Research
Radisic's general research focuses on treatments for myocardial infarction and drug cardio-toxicity screening. Her work centers on using human embryonic and induced pluripotent stem cells to develop a heart patch that could be used to study the safety and efficacy of new drugs as well as its compatibility with various cell lines. Radisic was the first author of a highly cited paper in PNAS where she successfully generated beating heart tissues from embryonic stem cells via electrical stimulation.[13]
Tissue engineering of cardiac patches
Radisic has worked on designing advanced bioreactors for cardiac tissue engineering capable of integrating mechanical and electrical stimuli with perfusion.[14] She has also conducted research on developing strategies to engineer vascularized myocardium based on the tri-culture of key heart cell types[15] using the engineered cardiac tissue as a model system for cardiac cell therapy or drug testing.[16]
Organ-on-a-chip engineering
Radisic's lab works on the development of injectable hydrogels with specific peptides such as QHREDGS peptide–modified hydrogel.[17] She also researched on the biometric cues in vitro and developed an engineered oriented cardiac tissue.[18] Radisic has also worked on other biomaterials such as moldable elastomeric polyester-carbon nanotube scaffolds for cardiac tissue engineering that will promote survival and localization of the cardio-myocytes injected into the infarcted myocardium.[19]
Radisic developed a flexible shape-memory scaffold for minimally invasive delivery of functional tissues. The scaffold utilizes a biodegradable polymer and a micro-fabricated lattice design to allow its shape memory property.[20] Her lab designed micro-fabricated cell culture systems with built-in electrodes and defined groove and ridge heights for simultaneous application of field stimulation and contact guidance cues, in order to understand interactive effects of multiple physical stimuli.
Radisic and her team developed a microfabricated system for generating 3D, aligned beating cardiac tissue (Bio-wire) from human pluripotent stem cells (hPSC) derived cardiomyocytes. The system utilized electrical stimulation to increase the maturation of hPSC derived cardiomyocytes. Bio-wire is the first system combining electrical stimulation with geometry control of 3D tissue assembly to improve the electrical and ultra-structural properties of human cardiac tissue.[21]
