Heat maps showing the amount of growth factors (reported in pg/mL) present in tissue extracts from amniotic membrane subjected to different storage times. Although the samples are from different donors, the trend is a drastic decrease in the number of growth factors present (as indicated by the white rectangles) upon prolonged storage of the amnion at − 80 °C prior to SCCO2 sterilization. Statistically significant (p < 0.01) higher quantities of growth factors found in SCCO2 amnion stored for less than six months are indicated by an “*”
