Comparison of the Proliferation and Differentiation Potential of Human Urine-, Placenta Decidua Basalis-, and Bone Marrow-Derived Stem Cells

Figure 5

Quantitative studies of the osteogenic, adipogenic, and chondrogenic differentiation abilities of USCs, BMSCs, and PDB-MSCs. (a) Alizarin Red- and Oil Red O-positive staining area analyzed by ImageJ (, compared to PDB-MSCs for osteogenic differentiation comparison; , compared to BMSCs for osteogenic differentiation comparison; , compared to PDB-MSCs for adipogenic differentiation comparison; and , compared to BMSCs for adipogenic differentiation comparison). (b) mRNA expression of aggrecan quantitated in USCs, BMSCs, and PDB-MSCs after 21 days of induction (). (c) mRNA expression of collagen II was quantitated in USCs, BMSCs, and PDB-MSCs after 21 days of chondrogenic induction (). BMSCs: bone marrow-derived mesenchymal stem cells; PDB-MSCs: placenta decidua basalis-derived mesenchymal stem cells; USCs: urine-derived stem cells; C: control; I: introduced.
