"As far as science is concerned, it\'s easier to see, to a limited extent, the parts than the whole. I am confident that the prestigious Westlake shall foster dedication, humbleness and diligence in me, who shall strive to see an ever bigger picture in the pursuit to better understand life and disease."
Biography
Dr. Shang Cai is currently the assistant professor in Westlake Institute of Advanced Studies. He received his bachelor degree of biological science in Peking University in 2003. He then went abroad to the Biochemistry Department of Indiana University for his PhD studies, working on the molecular mechanism of spindle assembly and chromosome alignment. After getting his PhD degree in 2009, he pursued his postdoc research in the Institute of Stem Cell and Regenerative Medicine, Stanford University, working on the mechanism of self-renewal and fate specification of mammary stem cell and breastcancer stem cell. He was promoted to research associate in 2015.

Research
Dr. Shang Cai’s research focused on the role of mammary stem cell in the morphological and functional integrity of the mammary gland during puberty, pregnancy and lactation, as well as the role of breast cancer stem cells in cancer initiation, evolution, drug resistance, relapse and metastasis. Through single cell gene expression analysis, he has successfully isolated a subset of mammary stem cells in quiescence, which can long-term self-renewal and regenerate mammary gland. He further identified a key transcription factor Bcl11b, which determines the quiescent state, and elucidated the molecular mechanism. In addition, his research revealed that a subset of stromal cells, positive for Gli2 expression, is responsible for the niche specification and mammary stem cell maintenance. Abnormalities in the Gli2 positive niche can cause mammary phenotypes associated with human disease of combined pituitary hormone deficiency (CPHD). This study provides insights in the treatment of the mammary underdevelopment for the CPHD patients.
Recent years, stem cell researches have gained much attention due to its potential for cellular therapy, organ repair and regeneration, but also are facing many bottlenecks for clinical applications. Our lab’s research interests focus on regenerative ability of stem cells, lineage specification and abnormalities of stem cells in various diseases. In the next five years, we are particularly interested in the following directions:
1. Lineage hierarchy of mammary cells and their dynamic changes during various developmental stages
2. The aberrant behaviors of stem cells in aging, hyperplasia and other diseases
3. The mechanism of drug resistance and metastasis of cancer stemcells.
