Abstract:

BACKGROUND: Mesenchymal stem cells as potential seeded cells have been widely used in tissue engineering and clinic therapy; thus, the precise, safe, effective isolation of mesenchymal stem cells is the particular important premise to build culture system.
OBJECTIVE: To review the methods of isolating mesenchymal stem cells and to compare the merit and demerit of different methods, thereby providing theoretical basis for safe and high-effective isolation of mesenchymal stem cells.
METHODS: A computer-based online research of CNKI and PubMed databases was performed to collect articles, which included reviews, clinical trials and experiments, published between 1965 and 2014 with the key words of “mesenchymal stem cells (MSCs), isolation methods” in Chinese and English. A total of 52 articles were included according inclusion and exclusion criteria
RESULTS AND CONCLUSION: (1) The whole bone marrow culture method can derive a mass of mesenchymal stem cells, which need to be purified. (2) The density gradient centrifugation method which uses the media with the density of 1.073 g/mL can be used to harvest more purified cells. (3) The tissue digestion method is suitable for digestion and isolation of adipose tissue and umbilical cord tissue. Type II collagenase digestion is better, but they are both limited by a high demand for operative techniques. (4) Immunomagnetic bead separation is appropriate to study the biological characteristics of a kind of subpopulation of mesenchymal stem cells which express special surface markers. (5) The combination method is also an optimal way. (6) Some new methods limited by few dates require further studies.
