Abstract
The human amniotic membrane HAM is an abundant and readily obtained tissue that may be an important source of scaffold for transplanted chondrocytes in cartilage regeneration in vivo To evaluate the potential use of cryopreserved HAMs as a support system for human chondrocytes in human articular cartilage repair Chondrocytes were isolated from human articular cartilage cultured and grown on the chorionic basement membrane side of HAMs HAMs with chondrocytes were then used in 44 in vitro human osteoarthritis cartilage repair trials Repair was evaluated at 4 8 and 16 weeks by histological analysis Chondrocytes cultured on the HAM revealed that cells grew on the chorionic basement membrane layer but not on the epithelial side Chondrocytes grown on the chorionic side of the HAM express type II collagen but not type I indicating that after being in culture for 3–4 weeks they had not dedifferentiated into fibroblasts In vitro repair experiments showed formation on OA cartilage of new tissue expressing type II collagen Integration of the new tissue with OA cartilage was excellent The results indicate that cryopreserved HAMs can be used to support chondrocyte proliferation for transplantation therapy to repair OA cartilageThis study was supported by grants Servizo Galego de Saúde Xunta de Galicia PS07/84 Catedra Bioiberica de la Universidade da Coruña and Instituto de Salud Carlos III CIBER BBN CB06010040 Silvia DiazPrado is beneficiary of an Isidro Parga Pondal contract from Xunta de Galicia A Coruna Spain Tamara HermidaGómez is beneficiary of a contract from Fondo de Investigación Sanitaria 2008 Spain Emma MuíñosLópez is supported by Rheumatology Spanish Foundation Spain We would like to thank MJ Sánchez and P Filgueira for technical assistance
