Biological characteristics of different sources of mesenchymal stem cells / 中国组织工程研究

ABSTRACT

BACKGROUND:Mesenchymal stem cels, underin vivo orin vitro specific induction conditions, can differentiate into the cartilage, muscle, tendons and so on. Clinical trials concerning mesenchymal stem cels mainly include tissue repair (such as bone, cartilage and joint repair) and treatment of heart, liver, spinal cord injury and nervous system diseases. OBJECTIVE:To compare the biological characteristics of mesenchymal stem cels from different sources. METHODS: PubMed and CNKI databases were retrieved for articles related to sources of mesenchymal stem cels and biological characteristics of mesenchymal stem cels published from 1987 to 2015. The retrieved articles were summarized and analyzed in the folowing aspects cel surface marker, proliferation, differentiation, migration, and function, so as to explore the merits and demerits of mesenchymal stem cels from different sources. RESULTS AND CONCLUSION:A difference in the proliferation ability and surface markers is found between different sources of mesenchymal stem cels. Immunological competence of mesenchymal stem cels from different sources may be correlated with their activation status, species differences, tissue sources and culture conditions, resulting the immunological competence of mesenchymal stem cels from different sources is not exact the same. In-depth understanding of the factors and mechanisms by which influence the migration of mesenchymal stem cels from different sources can enhance the migration ability of different sources of mesenchymal stem cels, and increase their efficiency in wound healing, tissue repair and regeneration treatment.
