A novel methodology in regenerative medicine: "The objective was to evaluate the utility of cryo-preserved human amniotic membrane (HAM) as a support for repairing human articular cartilage injuries, which have a very limited capacity for self-healing ... The results [show] that cryo-preserved HAM is useful as a scaffold for growing human chondrocytes in cell therapy and for repairing human cartilage injuries. ... It provides a more regular surface and fills in the cavities and fissures ... The authors cultivated the chondrocytes (cells that form part of the cartilaginous tissue), isolated from human articular cartilage, on the amniotic membrane over a period of three and four weeks. The amniotic membranes were used to develop 44 repair models of arthritic human articular cartilage in vitro, which was assessed between four and 16 weeks later. The HAM also bonds well with the native cartilage. ... In some models, we could not differentiate between where the native tissue stopped and the neo-synthesised tissue began. ... This tissue had a fibrous appearance and high cellular density (cellularity), which in some cases was greater than that of the actual native cartilage."
