Mesenchymal stem cells （MSC） are well-characterized population of adult stem cells. They have the potential to develop into mature cells that produce fat, cartilage, bone, tendons, and muscle. These properties in combination with their developmental plasticity have generated tremendous interest in the potential use of mesenchymal stem cells to replace damaged tissues. The fetal liver is the source of early hematopoietic cells and considered as a source of pluripotent stem cells. MSCs can differentiate into chondrocytes or osteoblasts. MSC have the capability for renewal and differentiation into various lineages of mesenchymal tissues. In essence, MSC can be cultured to expand their numbers and transplanted to the injured site or after seeding in/on shaped biomimetic scaffold to generate appropriate tissue constructs. HMSC-he from AcceGen Research Laboratories are isolated from human liver. HMSC-he are cryopreserved at passage one culture and delivered frozen. Each vial contains ＆amp;gt;5 x 10^5 cells in 1 ml volume. HMSC-he are characterized by immunofluorescent method with antibodies to CD73, CD90, CD105 and lipid staining after differentiation. HMSC-he are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HMSC-he are guaranteed to further culture at the conditions provided by AcceGen Research Laboratories.
