The APVBO 2019 conference aims to bring together the best vascular researchers, physicians and industry leaders across the world to showcase the newest progress, discoveries, challenges and promise in the field of vascular biology. The conference also aims to foster new collaborations, connect basic and translational research, and provide a high level platform of learning and communication to junior researchers.

    Guangzhou is the third largest city in China and the capital of Guangdong province, which ranks number one in China in terms of GDP through the years. Founded in 214 BC, Guangzhou has served as a springboard for trade, cultural exchanges, revolutions and reforms, and has played critical roles in shaping the modern China. Guangzhou also has the country's highest number of restaurants per capita. Apart from science, we hope that you will enjoy the great cuisine, natural beauty and the vibrant night life in Guangzhou too.
