Dear honorable guests and distinguished colleagues,
Thank you all for joining the 13th Pan Pacific Symposium on Stem Cells and Cancer Research (PPSSC 2021) virtual conference. Due to the challenges brought by the COVID-19 pandemic, the entire conference of PPSSC 2021 is taking place on a digital platform. I truly hope that you will enjoy the scientific program nonetheless.

I welcome our 25 eminent speakers from different countries who have come here, virtually, to share with us their knowledge in their fields of expertise. At the 13th PPSSC, the main speeches will cover a variety of topics: nanoparticles/exosomes research in cancer immunity and therapy, translation research of Chinese herbs during COVID-19 pandemic, the correlation between microbiome and diseases, neurological disorder and clinical translation of cellular and immune therapy.

We look forward to hearing your discussions and learning from your insights.

In closing, I would like to encourage the delegates to actively participate in all the activities and discussions via the digital platforms in the next two days. I wish everyone a successful, safe and fruitful conference.
