BACKGROUND: Studies have shown that the placenta contains a large number of hematopoietic stem cells. The limited supply of hematopoietic stem cells and other problems for therapeutic application are considered as the challenges in treating patients with hematopoietic malignancies and other diseases. * S9 u0 ]3 h2 R" L& OOBJECTIVE: To review the research progress of placental hematopoietic stem cells.9 A; L8 x. ^. P% ]# I
METHODS: A computer-based online search was performed in the PubMed database and the China National Knowledge Infrastructure database for the clinical and basic experimental research papers on placental hematopoietic stem cells published from January 2005 to November 2013. The key words were “placenta, hematopoietic stem cell” in Chinese and English. The articles published earlier and repetitive researches were excluded. , |0 _9 d3 p: a8 Y
RESULTS AND CONCLUSION: The placenta is a highly vascularized hematopoietic tissue that is important in the exchange of oxygen, nutrients and waste products between the foetus and mothers. In recent years, increasing studies have indicated that the placenta is also a source of hematopoietic stem cells and plays an important role in the development of hematopoietic stem cells. Compared to other sources of hematopoietic stem cells, the placenta has its unique advantages. Animal experiments have indicated that it plays an irreplaceable role in clinical applications in hematology and regenerative medicine. Undoubtedly, further basic and clinical trials in order to optimize and extend the placental blood stem cells in clinical applications are still needed.作者: taiqixia 时间: 2014-11-4 12:31
