BACKGROUND:Mesenchymal stem cel s as potential seeded cel s have been widely used in tissue engineering and clinic therapy;thus, the precise, safe, effective isolation of mesenchymal stem cel s is the particular important premise to build culture system.
OBJECTIVE:To review the methods of isolating mesenchymal stem cel s and to compare the merit and demerit of different methods, thereby providing theoretical basis for safe and high-effective isolation of mesenchymal stem cel s.
METHODS:A computer-based online research of CNKI and PubMed databases was performed to col ect articles, which included reviews, clinical trials and experiments, published between 1965 and 2014 with the key words of“mesenchymal stem cel s (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 cel s, 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 cel s. (3) The tissue digestion method is suitable for digestion and isolation of adipose tissue and umbilical cord tissue. Type II col agenase 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 cel s 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.

BACKGROUND:In previous studies, it is satisfied to sorting bone marrow mesenchymal stem cels based on natural sedimentation combined with low permeation. Then, based on particle hydromechanics theory, the settling velocity of bone marrow mesenchymal stem cels in culture liquid is calculated. A simple and easy method of separation, purification and proliferation of bone marrow mesenchymal stem cels is established by natural sedimentation velocity. OBJECTIVE:To explore the feasibility of sorting bone marrow mesenchymal stem cels by natural sedimentation velocity method. METHODS:The density interval of rabbit bone marrow mesenchymal stemcels (ρ1) was determined by density gradient centrifugation method. The diameter of rabbit bone marrow mesenchymal stem cels (d) was measured by scanning electron microscope. The density of culture liquid (ρ2) was measured by liquid density meter. The viscosity of the culture liquid (μ) was measured by viscosity meter. The settling velocity of bone marrow mesenchymal stem cels (Vt) was derived from the above four numerical values with the appropriate formula. Bone marrow mesenchymal stem cels were sorted from bone marrow tissue by natural sedimentation velocity method. Cel proliferation, purity and differentiation were observed. Meanwhile, the primary culture time of three different cel sorting methods was recorded; the colony formation rate of rabbit bone marrow mesenchymal stem cels was determined. RESULTS AND CONCLUSION:(1) The diameter of rabbit bone marrow mesenchymal stem cels was (20.37±4.58) μm, and the setting velocity of rabbit bone marrow mesenchymal stem cels in the culture liquid was 50-55 mm/h. (2) Bone marrow mesenchymal stem cels could be successfuly isolated from bone marrow tissue of rabbits by the natural sedimentation velocity method, which could be induced into osteoblasts and adipocytes. (3) The natural sedimentation velocity group cost less time than the other two density gradient centrifugation groups in the primary culture stage. The colony formation rate of the natural sedimentation velocity group was higher than that of the other two groups. (4) Natural sedimentation velocity method did not impose any intervention measures for sorting cels, which maybe maximaly maintain cel viability and biological characteristics. The whole separation process was simple and safe, which may have little damage to the cels.
