- 요약This doctoral thesis focuses on the engineering of in vitro models for studying lymphatic network sprouting. The lymphatic system is crucial for maintaining tissue fluid homeostasis, immune cell trafficking, and fat absorption. Lymphangiogenesis, the formation of new lymphatic vessels, involves complex interactions between key ligands and their receptors, such as vascular endothelial growth factor C (VEGFC) and vascular endothelial growth factor receptor 3 (VEGFR3), which regulate lymphatic endothelial cell (LEC) sprouting. Supporting cells, as well as biochemical and biomechanical cues provided by the tissue microenvironment, also play pivotal roles in this process. This dissertation showcases the development of tissue-engineered models using primary lymphatic cells to elucidate the mechanisms of lymphatic sprouting and remodeling. These models aim to overcome the limitations of in vivo studies by offering reproducible platforms for investigating lymphatic biology and testing potential therapeutic interventions.Additionally, the thesis explores a precision medicine approach for managing lymphatic malformations (LMs). Tissue samples were collected from patients undergoing routine sclerotherapy and expanded in polyethylene glycol (PEG) hydrogels to create patient-derived cells (PDCs). These PDCs were then characterized for their genetic fidelity to the original tissue biopsy using single-cell RNA sequencing and whole exome sequencing. Patient-derived organoids (PDOs), termed lymphatic malformation organoids (LMOs), were developed and assessed for their lymphatic sprouting capacity in PEG hydrogels.The final chapter examines the differential responses to PI3K/AKT/MTOR pathway inhibition in LMOs. Specifically, it investigates the regression of LMOs following treatment. The results demonstrated significant variability in drug responses among LMOs derived from three different patients, highlighting the heterogeneity of LMs. Gene expression analyses revealed that alpelisib treatment upregulated pro-apoptotic genes, providing insights into the molecular mechanisms driving sprout regression. Overall, this thesis underscores the potential of targeted therapies for managing LMs, the value of using patient-derived models for precision medicine, and the impact of in vitro models on advancing our understanding of lymphatic biology.
