A Preliminary Study Comparing Microfracture and Local Adherent Transplantation of Autologous Adipose-Derived Stem Cells Followed by Intraarticular Injection of Platelet-Rich Plasma for the Treatment of Chondral Defects in Rabbits.

Objective This study aimed to compare microfracture and application of adipose-derived stem cells (ADSCs) by local adherent technique enhanced by platelet-rich plasma (PRP) to provide a new approach for the repair of cartilage defect. Design Full-thickness cylindrical defects were created in the medial femoral condyle in 9 New Zealand White rabbits (5 months old, 4.65 ± 0.

Isolation, cultivation and characterisation of pigeon osteoblasts seeded on xenogeneic demineralised cancellous bone scaffold for bone grafting.

Avian osteoblasts have been isolated particularly from chicken embryo, but data about other functional tissue sources of adult avian osteoblast precursors are missing. The method of preparation of pigeon osteoblasts is described in this study. We demonstrate that pigeon cancellous bone derived osteoblasts have particular proliferative capacity in vitro in comparison to mammalian species and developed endogenous ALP.
