The Cheng lab studies human stem cell biology and engineering to develop experimental models of and treatments for human blood diseases. The team has made several discoveries in understanding human stem cell self-renewal and hematopoietic (blood-forming) differentiation using adult hematopoietic stem cells and human pluripotent stem cells. They also poineered recently efficient methods to establish human induced pluripotent stem (iPS) cells from both blood cells and fibroblasts by plasmids without integrating into cellular chromosomes. In effort to develop better genetic models and gene therapy methods, the Cheng lab develops new methods for making genetic modifications in human cells using various methods such as human genome editing.
Stem cell biology, Human iPS cells and reprogramming, human genome engineering, genome editing
Dr. Cheng's main laboratory is working on human stem cell biology and engineering, and their applications in regenerative medicine for curing blood diseases. One of their objectives is to understand genetic and epigenetic regulation of cell fate determination in hematopoiesis. The group currently focuses on using human pluripotent stem such as iPS cells from healthy donors and patients. They use both cellular differentiation and genetic approaches such as genome editing to orrect or create mutations in human stem cells. Their goals is to investigate human stem cell biology and diseases. More details are available on his lab website www.stemcelllab.org
