CHEN Yonglong
Associate Professor

Dr. Yonglong Chen is an associate professor at Southern University of Science and Technology. Dr. Chen received his B. Sc. and M. Sc. Degrees from Northwest Normal University, China and Ph. D. degree from Essen University, Germany. From 1999 to 2007, he had postdoctoral training at University of Goettingen, Germany. From 2007 to 2014, he had established his independent laboratory at Guangzhou Institutes of Biomedicine and Health, Chinese Academy of Sciences, as a principal investigator. Since 1999, his research interests have been focused on the understanding of molecular mechanisms of pancreas development and regeneration of pancreatic beta cells both in vivo and in vitro, which holds great potential for cell transplantation therapy of diabetes. He has published 55 papers in peer-reviewed journals, such as Genes & Development, PNAS, EMBO Journal, and Development.

Research Interests
◆Pancreas development and regeneration. We use Xenopus as a model to investigate how embryonic endodermal precursors are specified into pancreatic buds and further developed into a functional pancreas. We are also interested in studying the regeneration mechanisms of adult pancreatic cells, including islet beta cells.
◆Xenopus modeling of human diseases, such as pancreatic cancers and lung cancer.
