Alizarin red staining at 14 days on (1) control barrier membranes without ST2 cells, (2) barrier membranes pre-coated with BCM without ST2 cells, (3) ST2 cells on control barrier membranes and (4) ST2 cells on barrier membranes pre-coated with BCM. Semi-quantified evaluation of alizarin red staining. Pre-coating collagen membranes with BCM significantly increased alizarin red staining as assessed by colour thresholding software (* denotes significantly higher compared with the other modalities, p < 0.05)
