    Abstract

    Background: The amniotic membrane is a favorable biomaterial to apply in the field of tissue engineering because of its unique biological properties. Human amniotic membranes consist of 2-layered sheets containing numerous growth factors, cytokines and other bioactive substances. Methods: In this study, we explored the potential of amnion membrane extracts (AME) and amnion/chorion membrane extracts (A/CME) to promote osteogenic differentiation of osteoblast-like (MG-63) cells. MG-63 cells were cultured in osteogenic induction medium (OIM) with or without 100 μg/mL of AME or A/CME. To determine the early and late differentiation of osteogenesis, alkaline phosphatase (ALP) activity and calcium deposition were measured at 3, 7, 10 and 24 days. Expression of specific genes associated with osteogenic differentiation, including osteocalcin (OCN), osteopontin (OPN), runt domain-containing transcription factor (Runx2) and osterix (OSX) was also determined. Results: In vitro experiments demonstrated that A/CME increased ALP activity, osteogenic gene expression and mineralization under osteogenic-inducing conditions. Notably, we found that A/CME contained growth factors related to osteogenesis, including fibroblast growth factors and transforming growth factors, which potentially promoted osteogenic differentiation of MG-63 cells to a greater extent than AME. Conclusions: These results indicate that A/CME is capable of providing growth factors and other substrates for osteogenic differentiation, which significantly increased the efficacy of osteogenesis in MG-63 cells. Taken together, the results of this study suggest that human A/CME is a promising biomaterial with therapeutic potential in bone regeneration applications.
