Fig. 3

Transforming growth factor-β1 (TGF- β1) fold change in platelet-rich plasma (PRP) at 1, 3, and 6 months of storage in − 20 °C automatic defrost freezer (− 20A), − 20 °C manual defrost freezer (− 20 M), − 80 °C manual defrost freezer (− 80 M), and liquid nitrogen (LN) compared to baseline fresh activated PRP at time 0 (PRP0). All samples were activated with bovine thrombin and calcium chloride prior to growth factor quantification at each time point. Bars represent mean (n = 6) ± standard error. Differing letters indicate a significant difference between groups within storage method, using a repeated measures ANOVA with a Tukey post-hoc test, p < 0.05
