Project title:
Tissue engineering of blood vessels using three-dimensional bioprinting of endothelial and smooth muscle progenitor cells
Project team:
Dr. Florin Iordache, Project Director
Dr. Adriana Georgescu, Mentor
Project summary:
The goal of tissue engineering is to generate living tissue constructs in vitro
that are morphologically and functionally similar to native tissue. Growing physiologically relevant
tissues requires multidisciplinary research where the resulting tissues can be used for the study of
human development and disease, to test the efficacy and toxicity of compounds and treatments,
and for regenerative medicine applications. Lately, the tissue engineering of a small-diameter
blood vessel substitute has become very important for cardiovascular researchers. In vascular
surgery blood vessel grafts made of synthetic polymers have the disadvantage of thrombosis,
rejection, intimal hyperplasia, calcification, chronic local inflammation. A new alternative may
come using tissue engineering of blood vessels that uses biodegradable 3D scaffolds as an
alternative for extracellular matrix, and stem cells that are seeded into the scaffolds. Thus, the
purpose of proposed project is to create artificial blood vessels using endothelial (EPCs) and
smooth muscle (SPCs) progenitor cells and polymeric biomaterials based hydrogels as scaffold.
Specifically, the efficiency of medical scaffolds and their influence on eukaryotic cells are the most
important parameters in determining the impact of these biomedical materials. Biocompatibility
and organization of progenitor cells will be evaluated at biochemical, cellular and molecular level.
The functionality of blood vessel construct will be evaluated using myograph techniques. The
elements of originality and innovation of the project consist in the experimental design that
combines the different progenitor cells with the new 3D technology that permit a better and
controlled deposition of cells in a 3D scaffold. With the proposed project, we aim to provide proof-
of-concept that tissue engineering of blood vessels using 3D bioprinting of EPCs and SPCs, might
represent a valuable new therapeutic strategy for cardiovascular regenerative medicine.
Objectives:
1. Obtaining and characterization of the progenitor cells and blood vessel structure/model.
2. Accomplishing 3D-printed blood vessel structure and investigating biocompatibility of EPCs and SPCs in the presence of BioInk hydrogel.
3. Evaluating morphology and adhesion ability of EPCs and SPCs embedded in BioInk hydrogel.
4. Structural and functional characterization of vascular structure obtained using 3D bioprinter.
