Mesenchymal stem cells are the adult stem cells. Mesenchymal stem cells are of various types such as monocytes, adipocytes, osteocytes and chondrocytes. Mesenchymal stem cells main function is to replace or repair damage tissue. In addition, mesenchymal stem cells have high potential for tissue repair. Mesenchymal stem cells are isolated from other tissues such as fallopian tube, cord blood, fetal liver, peripheral blood and fetal lung. Mesenchymal stem cells are renewable source to substitute tissue and cells to treat disabilities and diseases.
