Show moreTo improve the predictive capability of pre-clinical models and reduce the use of animal models in drug discovery and disease modelling, advanced in vitro models are being developed. These microphysiological systems (MPS) or “Organs-on-Chip” (OoC) are being developed to include all aspects of the human physiology to improve the in vitro cellular response. OoCs combined with differentiated human induced pluripotent stem cells (hiPSC) allow the use of cells with patient specific genotypes and aid the development of personalized and precision medicine.In this thesis, the development of tractable models of the vasculature is described. These models allow for the combination of hiPSC-derived vascular and tissue specific cells with haemodynamics to recapitulate essential stimuli of blood vessels. Show less

Show moreOne of the major limitations in culturing complex tissues or organs is the lack of vascularization in the cultured tissue. Development of a functional capillary bed could overcome this problem. The zebrafish is a promising model for in vitro vasculogenesis and angiogenesis studies, as a replacement for currently used mammalian models. However, the culture of endothelial cells from this species is not well characterized. Here, we test different culture strategies, medium supplementations and culture substrates for their effect on the generation of putative endothelial (fli:GFP+ and kdrl:GFP+) cells and vascular morphogenesis in zebrafish blastocyst cell derived embryoid body culture. we have also developed a perfused culture model, using microfluidic technology, to culture zebrafish vascular networks. This study is a step forward to the development of zebrafish vascular networks in vitro. Show less
