Research Description:

Human pluripotent stem cells (hPSCs), either derived from the early embryo (ES), or induced from somatic cells (iPS), can undergo indefinite self-renewal and differentiate into any cell type in the human body, thus hold great potential for clinical use in regenerative medicine. The research in Pan’s laboratory focus on three parts mainly: 1. To understand the mechanisms by which control the cell fate maintenance and transition of hPSCs. Using hPSCs as a model, the laboratory analyzes how different biological processes such as transcription factors mediated expression profile, signaling pathway, epigenetic change involved in the regulation of cell fate transition; 2. To generate functional neural progenitor cells (NPC) and hematopoietic stem/progenitor cells (HSC/HPC) from hPSCs. The researchers are trying to gain functional HPC and reveal the mechanisms involved in differentiation regulation through an integrated approach using molecular biology, cell biology, epigenetics, genomics, FACS, confocal microscopy and so on. For the hPSCs derived NPCs, after the NPCs are tested for their therapeutic potential in animal models, the final goal of this research is to translate the technology to the re-building of the injured or diseased human brain. 3. To generate highly efficient transgene-free patient’s iPSCs for human disease modeling. The genetic defects in patient derived iPSCs will be corrected and the iPSCs will be differentiated into functional somatic cells for clinical use.

The major achievements of Pan’s laboratory include: 1. Developed an efficient approach to directly convert human urine cells (hUCs) into neural progenitor cells and revealed the role of TGFβ in shaping cell fate during hUCs trans-differentiation; 2. Developed an efficient approach to generate iPSCs from hUCs in a serum-free, virus-free and animal-product free system; 3. Set up an optimized CRISPR/Cas9 platform for rapid hPSCs genome editing efficiently. Based on this platform, the researchers have corrected HBB mutation of β-Thalassemia iPSCs and discovered that polycomb repressive complex 2 is required for maintenance of human embryonic stem cells; 4. Established a system for hematopoietic differentiation of hPSCs and identified CD61 as a specific marker of hemogenic endothelial cells through constructing a GATA2 reporter cell line.

The future research of Pan’s laboratory will focus on the clinical translational research of NPCs; the mechanisms of heterogeneity and cell fate determination during hPSCs differentiation.
