Professor Pengtao Liu is the S Y and H Y Cheng Professor in Stem Cell Biology and Regenerative Medicine at the School of Biomedical Sciences, Li Ka Shing Faculty of Medicine, The University of Hong Kong. He is the founding and managing director of the InnoHK Centre for Translational Stem Cell Biology at Hong Kong Science and Technology Park. Professor Liu earned his PhD from Baylor College of Medicine and completed postdoctoral training at the National Cancer Institute in the United States. 


Prior to joining HKU, he established and led a research laboratory at the Wellcome Trust Sanger Institute, Cambridge, and served as an affiliate faculty member at the Cambridge University Stem Cell Institute. His key contributions include participating in large-scale mouse genetics projects, discovering a novel killer cell that eliminates cancer cells, and developing Expanded Potential Stem Cells (EPSCs). Notably, he established the first stable pluripotent stem cells from pig preimplantation embryos.


In Hong Kong, Professor Liu spearheads major research initiatives at HKU and InnoHK CTSCB, supported by the InnoHK initiative of the Innovation and Technology Commission of the Hong Kong Special Administrative Region Government. As a pioneer in stem cell research, his team continues to advance scientific frontiers through innovative discoveries with the potential to revolutionize medicine. Their work helps position Hong Kong as a global hub for stem cell research and cell-based therapies, shaping the future of regenerative medicine and personalised treatments.

  • Fundamental stem cell biology
  • Epigenetic regulation of stem cell development
  • Molecular factors for direct cell reprogramming and cell-fate conversion
  • Stem cell-based technologies for virus propagation
  • Development of antiviral drugs and vaccines using stem cell models
  • Cellular models that mimic normal human cell aging for anti-aging research
  • Discovery and characterization of novel stem cell sources for regenerative medicine

The Liu lab developed the Expanded Potential Stem Cell (EPSC) technology, which has wide-ranging applications in fundamental biology, regenerative medicine, cell-based therapy, organ transplantation, biotechnology and agriculture. The lab's primary objective is to generate and characterize novel stem cell lines exhibiting totipotency features across multiple mammalian species, and to direct these stem cells to generate functional cell types, such as immune cells, both in vitro and in vivo. This approach is fundamental for advancing our understanding of human development, improving therapeutic strategies, and expanding the therapeutic potential of stem cells. The lab employs advanced molecular and functional methodologies, particularly single-cell multi-omics, to elucidate the underlying molecular mechanisms governing stem cell biology.
