Gene expression analysis of chondrogenic markers. Relative gene expression of chondrogenic marker genes in the individual donor samples. a S100B, b CRTAC1, c ACAN. Sample #5 was set to 1 and the other samples were expressed relative to sample #5. Each sample was analysed in triplicates. Due to the low numbers of generated spheroids for donor #9 and #13, no spheroids were available (n.a.) for qPCR analysis of these samples. The calculation of gene expression levels was based on the ΔΔCt method. The gene expression levels were normalized to GAPDH gene expression levels
