A fundamental problem in tissue engineering is the fabrication of tissues with an embedded vasculature—functional at all relevant length scales, down to the cellular scale where the smallest vessels are to deliver nutrients and remove metabolic byproducts. Current approaches to engineering of capillary networks typically rely on spontaneous selfassembly of the endothelial cells (EC), suspended in an external hydrogel–mimicking the extracellular matrix of the native tissue–into branched tubular networks. However, such self-assembled networks are typically far from optimal. In particular, (i) they develop slowly in time (the cells need to migrate over relatively large distances), (ii) they are heterogeneous and weakly percolated, (iii) they do not allow any external control over the vessel distribution, connectivity and general network topology. In this project, we will develop a new method of vascular tissue engineering based on the use of EC ‘seeds’, that is aggregates of ECs or microbeads coated with ECs, suspended in an external 3D hydrogel matrix. It is known that EC aggregates tend to spontaneously ‘sprout’ into the matrix, i.e., develop tubular protrusions, precursors of the microvessels. In the project, we will use the sprouting seeds as building blocks of larger, interconnected vascular constructs. To this end, we will develop a new technique of directed-assembly of EC-coated microbeads into ordered arrays using magnetic forces. We will assemble the arrays inside a hydrogel-filled microfluidic chamber allowing longterm culture and facilitating confocal time-lapse imaging of the developing microvasculature. To rationalize the observed topologies, we will develop a data-driven theoretical model of the dynamically evolving vascular networks. In particular, based on the theory cross-validated with experimental data, we will determine the optimal conditions for the development of networks of highest possible connectivity and viability. Finally, we will use our EC bead-based experimental platform to study the development of microvasculature in cancer tissues. For this purpose we will co-culture the endothelial seeds with cancer cells and characterize the impact of the outgrowing microtumors on the topology of the ingrowing capillary networks. The platform enables tracking of individual cancer cells upon their extravasation into co-cultured micro-vessels, which we will use to quantify the metastasic potential of cancer cells. We will use various sub-types of breast cancer cells and study the response of the ensuing microtumors to anti-cancer drugs as a proof-of-concept of a personalized approach to cancer treatment. Altogether, in the project, we will establish a highly controlled and versatile tissue-on-chip platform for studying basic mechanisms of angiogenesis in healthy and diseased tissues as well as for future applications in personalized cancer therapies.
