Alkaline phosphatase activity of periodontal ligament stem cells seeded on PADM and HAp-PADM.
Notes: Data were normalized for total protein content to account for the effect of the different number of cells on each scaffold. Data represents mean ± standard deviation (n = 5, five replicates per time point for each experimental condition); *P < 0.05; **P < 0.01 (PADM versus HAp-PADM).
Abbreviations: HAp-PADM, hydroxyapatite-coated porcine acellular dermal matrix; PADM, porcine acellular dermal matrix.
