Whatisastemcell?

CharacteristicsofMesenchymalStemCells(MSC)

• MSC are defined by :• Adherence to plastic• Fibroblast like morphology• Differentiation potential : fat, bone, cartilage• Phenotype characteristics :

• Negative : CD11b, CD14, CD34, CD45• Positive : CD90, CD105, CD73, ….

• Enhance hematopoietic stem cell engraftment• Tissue reconstitution• Immuno supressive properties• Self-renewal
