Expression fold differences represent the ratio of means of (Target Gene/Actb)_{Group A}/(Target Gene/Actb)_{Group B}. PERI: peritenon-derived progenitors; TP: tendon proper-derived progenitors. Days in culture: pre-seeded (PS), 7 days in construct (7), 45 days in construct (45). Statistical significance of fold changes are in bold (^aP <0.05; ^bP <0.01); two-tailed unpaired Mann–Whitney-Wilcoxon tests were performed. Graphical representations of the data are found in Figure 4.
