Corneal stromal cells from six donors were used and expanded in standard conditions (FBS as a supplement) and xenofree conditions (HPL as a supplement). Bone marrow MSCs from one other donor were used as a comparative control. From the purified RNA, 10ng was used per sample to synthesize cDNA using the iScript Advanced cDNA synthesis kit (Bio-Rad Laboratories, Temse, Belgium) following the protocol supplied by the manufacturer. qRT-PCR assays were prepared in triplicate in 96-well PrimePCR plates for human MSCs (Bio-Rad Laboratories, Temse, Belgium), in which the primers come lyophilized per well. A total of 88 genes was targeted, which account for stemness, differentiation (osteo-, chondro-, adipo-, teno- and myogenesis), MSC-specific, and MSC-related genes. The thermal cycler used to perform the PCR was the CFX96 Real-Time System – C1000 Thermal Cycler (Bio-Rad Laboratories, Temse, Belgium). SsoAdvanced universal SYBR Green supermix was used to quantify double-stranded DNA. Dissociation of double-stranded DNA was assessed in melting curve analysis to determine the specificity. Three reference housekeeping genes were included in the assay plates (TBP, GAPDH and HPRT1) to normalize expression using the ΔΔCq method. The abundance of the transcripts in CS-MSC relative to the control BM-MSC was determined by calculating the relative normalized expression (RNE) or fold change. All analyses were performed using the Bio-Rad CFX Manager software. When gene expression exceeds a more than threefold change compared to BM-MSC it is deemed to be up- or downregulated. Overall design: qPCR gene expression of 88 genes specific for, related to or associated with MSCs. Corneal stromal cells from six donors were used and expanded in standard conditions (FBS as a supplement) and xenofree conditions (HPL as a supplement). Bone marrow MSCs from one other donor were used as a comparative control. All plates were run in triplo. Less...
