On August 3, 2004, three major national research projects, undertaken by the Northwest S&T University for Agriculture and Forestry, and the Shan'xi Branch of the National Stem Cell Engineering Research Center, including "Construction of Human Pancreas Stem Cells", " Plasticity of Epidermis Stem Cells and its Applications in Corneal Transplanting", and "Frozen Corneal Edge Stem Cell based Corneal Epidermis Construction and Associated Transplanting", passed the verification checks organized by the Ministry of Education in Yangling, Shaan'xi Province.

"Construction of Human Pancreas Stem Cells", a project undertaken by the study team headed by Prof. DOU Zhongying, a Chinese expert in stem cell engineering, has worked out the world's first human embryo's pancreas stem cells. Human Pancreas Stem Cells can grow to pancreas cells that could secrete insulin. If doctors transplant these kind of cells to diabetic patients, the patients can produce the insulin by their own body. Then they are free from the disease.
