MSc Study:

In Vitro Bone Tissue Engineering On Patterned Biodegradable Polyester Blends

Cell alignment on PHBV-P(L/DL)LA microgrooved films had no effect on cell proliferation, while a significant improvement in osteoblast function  was obtained on fibrinogen  adsorbed micropatterned films 


Research Field:

3D Patterned Cardiac Tissue Construct Formation Using Biodegradable Materials


Heart failure, that can be caused by heart attack or congenital heart defects, is the number one cause of death in industrialized nations. One of the contributing factors in the progression of heart failure after heart attack is the loss of cardiomyocytes, cells of myocardium that contract to generate the blood pumping action of the heart. The injured myocardium is replaced by a fibrous scar, promoting the development of ventricular function loss, where currently allogenic heart transplantation is the only effective treatment. Unfortunately, heart transplantation is limited due to inadequate organ donations. Restoration of heart function by replacement of diseased myocardium with functional cardiac myocytes offers a potential cure. The elementary myocardial functional units are myocardial cells that are integrated into a multicellular assembly of myofibers aligned in parallel to each other. This study aims improvement of ventricular restoration procedures by providing a bioengineered graft that homes mesenchymal stem cells (MSCs) from umbilical cord matrix (Wharton's Jelly) aligned in parallel to each other on electrospun polymer microfibers in 3D architecture and biodegradable macroporous tubings used to supply growth media to the cells within the structure. The 3D construct obtained through tissue engineering approach and grown in a bioreactor demonstrated a uniform distribution of aligned viable cells for the duration tested (2 weeks).
