Stem Cell Introduction     Life science is the subject that develops the most rapidly in natural science at the end of 20th century and the beginning of this century. The development and application of stem cell become one of the most outstanding area. In 1999, the new discovery of stem cell research leads Science "Top Ten" list of the best scientific advances. In 2000, it was again selected in "Top Ten" list of the best scientific advances of the world. At the present time, stem cell researches are almost being applied in all areas of life science and biological medicine.” Famous biologist E.B. Wilson said: All the answers of biological problems must ultimately be sought in the cells, for every living organism is, or at some time has been a cell. What is Stem Cell     Human body is constituted by 4 to 6 trillion cells; there are over 230 kinds and two broad categories, functional cell and stem cell. The first category is functional cell, whose life activities embody humans various physiological functions. For example, heart is consisted of myocardial cells, whose rhythmical contraction and diastole realise the  physiological function of the heart. Human thinking is realised by neurons transmitting information in brain. We can say that because of the completeness and activeness of functional cell, we can stay young, healthy and energetic.     Just like people, cells will die. Normal cell apoptosis and cell necrosis caused by external factors can make people lose a plenty of functional cells. So we need another kind of cells to regenerate new functional cells to replace apoptosis and necrosis cells. These kinds of cells that can regenerate new cells are stem cells. Stem cells exist in all the tissues and organs in human body. The quantity and quality of stem cells determine the functional state of tissues and organs.Stem cell is also organism; their lives also experience the process of growth, development, maturity, senescence and death in accordance with the order of nature. With age increasing, the quantity and quality of stem cell in body decrease gradually. They can not regenerate young and healthy cells according to the body needs to replace senescent and lesion cells. Ultimately, they reflect peoples senescence and disease.     So restoring the quantity of active stem cells is the key to prevent senescence, preventing and curing various diseases.  

      In 2002, Stem Cell Bioengineering Research Center of Jilin Province, a domestic stem cell technology authority, cooperated with Stem Cell Research Center of USSR, introducing such world cutting-edged techniques as purification, identification, amplification and directed inducement, solving the rejection problem bothering stem cell transplantation. It also developed the technique of stem cell culture independently, making stem cell an industry.   In the same year, Jilin University Tongyuan Bioengineering Co., Ltd. invested 500m yuan on advanced techniques approved by world qualification inspection organization, putting a domestic top-ranking stem cell culture base that can provide stem cells for 3000 individuals annually in place. Stem cells there have undergone detections of toxin and heat origin of bacteria with the most advanced method in the world by authorities. Experimental environment in the laboratories there are also in accordance with GMP.   Stem cell transplantation technology has also caught great attention of leaders from both provincial and municipal level. Wang Yunkun, Party Secretary of Jilin Province, Wang Rulin , Party Secretary of Changchun as well as Zhu Yejing, mayor of Changchun visited Stem Cell Bioengineering Research Center of Jilin Province and encouraged the staff to spare more efforts on the further development and clinical use of stem cell transplantation.   Through unremitting efforts, the center has developed hematopoietic stem cells and neural stem cells for clinical application successfully, making clinical application of stem cell transplantation possible in Jilin Province. The center has been approved access to clinical application by Ministry of Health of the People’s Republic of China.   Jilin Guigu Hospital is a modern non-profit general hospital covering an area of 575,000 ㎡ with a total investment of 300m yuan behind it. It has got the approval of Department of Public Health of Jilin Province   Jilin Guigu Hospital is composed of a medical exam center, a stem cell transplantation center and a cardiovascular center, such divisions as endocrinology, oncology, surgery and neurology. It has introduced what is crowned as “Laurel of Modern Medicine”---PET-CT to record the trace of canceration in human body at the cellular level and find the location of cancer cells correctly, ensuring the early diagnosis. PET-CT plays an incomparably important role in correct diagnosis of diseases.     In Jilin Guigu Hospital，medical staff composed of experts have employed the most advanced and safest stem cell transplantation techniques to provide the best medical plans suitable for each patient’s different case. For most cases including diabetes, heart disease, and liver disease and so on, they can be cured through stem cell therapy.   Furthermore, stem cell transplantation can also help people become stronger, more energetic and improve people’s sub-health.     More than 10,000 patients have received the stem cell therapy in the past 8 years. They all recovered form their former diseases which is an obvious evidence of effective treatment. It is the new therapy of stem cell transplantation in Jilin Guigu Hospital that helps patients out of their pains.   Stem cell transplantation shares more parts in improving people’s lives.
