Additional file 1: Fig. S1. Characterization of human Wharton’s jelly-derived mesenchymal stem cells (WJ-MSCs). A: The morphology of WJ-MSCs was photographed under a phase-contrast microscope. B-F: Flow cytometric analysis of hematopoietic markers (CD34 and CD45) and the expression of mesenchymal stem cell markers (CD73, CD90 and CD105). Fig. S2. MTS analysis of cell viability on 0 and 21th day after chondrogenic differentiation. A: cell viability in control and IUGR groups. n = 8. B: cell viability in 300, 600 and 1200 nM cortisol groups. n = 8. Data are mean ± S.E.M. Fig. S3. Serum cortisol levels of umbilical cord blood from IUGR and normal individuals by enzyme-linked immunosorbent assay. Control group: n = 15, IUGR group: n = 14. IUGR, intrauterine growth retardation. Data are the mean ± S.E.M. **P
