As a dedicated physician-scientist and bioengineer, Dr. Hsieh's research endeavors have spanned diverse areas, yielding impactful contributions to cardiovascular regeneration, cancer nanomedicine, microbiota and metabolism, iPSC technologies, and translational research. Some key achievements include:
Cardiovascular regeneration insights: Investigated postnatal cardiomyocyte potential for proliferation, employing isotope-imaging NMR/mass spectrometry, genetic fate-mapping mouse models and human iPSC-derived cardiac cell transplantation in nonhuman primate models to explore novel therapeutic targets for promoting adult cardiomyocyte regeneration after myocardial infarction (MI). (Nat Med 2007, Sci Transl Med 2012, EMBO MM 2014, Circ Res 2015, Circulation 2023)
Cardiomyocyte reprogramming: Explored cardiomyocyte reprogramming into cardiac stem/progenitor cells, identifying a gene cocktail (FoxM1, Id1, Jnk3-shRNA) that induces cardiomyocyte proliferation in vitro and in vivo. Demonstrated improved cardiac function and reduced fibrosis after MI, offering a practical strategy for tissue regeneration. (EMBO MM 2017, Circulation 2022)
Microbiota and cardiac repair: Investigated the role of gut microbiota-derived short-chain fatty acids in post-MI repair in mice, nonhuman primates and patients with ST-elevated MI. Established a link between gut microbiota composition and host immune composition, providing insights for potential modulation of pathological outcomes after MI. (Circulation 2019, Nat Comms 2023)
Nanomedicine innovations: Developed a reloadable multi-drug capturing delivery system for targeted ischemic disease treatment, showcasing the potential for sequential administration of protein drugs in murine and porcine models. This technology has been transferred for further development by a Taiwan-based company. (Circulation 2010, Sci Transl Med 2016)
Blood-brain barrier permeability: Developed a strategy using low-dose VEGF to induce a transient increase in blood-brain barrier permeability, enabling enhanced delivery of nanomedicines for glioblastoma treatment. Demonstrated applicability in mouse models and pigs, showcasing potential clinical translation. (Sci Transl Med 2012, ACS Nano 2019)
Immune cell shuttle for nanotherapeutics: Designed aptamer-based lipid nanovectors that actively bind to monocytes, enabling precise delivery of nanotherapeutics for heart disease and cancer. Successfully treated cardiac ischemia-reperfusion injury and pancreatic ductal adenocarcinoma. (Adv Healthc Mat 2016, Sci Adv 2021)
National iPSC Core leadership: Led Taiwan's national iPSC Core, a collaborative effort involving IBMS, National Taiwan University Hospital, Taipei Veterans General Hospital, National Health Research Institutes, and Food Industry Research and Development Institute for eight years. Generated over 500 human iPSC lines and established the Taiwan iPSC Bank containing 112 human iPSC lines for public use, elevating Taiwan among the top 5 iPSC banks globally.
