چکیده
objective (s): the scarcity of articular cartilage defect to repair due to absence of blood vessels and tissue engineering is one of the promising approaches for cartilage regeneration. the objective of this study was to prepare an extracellular matrix derived decellularized bovine articular cartilage scaffold and investigate its interactions with seeded rat bone marrow mesenchymal stem cells (bm-mscs). materials and methods: bovine articular cartilage that was cut into pieces with 2 mm thickness, were decellularized by combination of physical and chemical methods including snap freeze-thaw and treatment with sodium dodecyl sulfate (sds). the scaffolds were then seeded with 1, 1’-dioctadecyl-3, 3, 3’, 3’-tetramethylindocarbocyanine perchlorate (dii) labeled bm-mscs and cultured for up to two weeks. results: histological studies of decellularized bovine articular cartilage showed that using 5 cycles of snap freeze-thaw in liquid nitrogen and treatment with 2.5% sds for 4 hr led to the best decellularization, while preserving the articular cartilage structure. adherence and penetration of seeded bm-mscs on to the scaffold were displayed by histological and florescence examinations and also confirmed by electron microscopy. conclusion: ecm-derived decellularized articular cartilage scaffold provides a suitable environment to support adhesion and maintenance of cultured bm-mscs and could be applied to investigate cellular behaviors in this system and may also be useful for studies of cartilage tissue engineering.

متن کاملbovine articular cartilage decellularized matrix as a scaffold for use in cartilage tissue engineering
extracelllar matrix (ecm) materials from mammalian tissues have been broadly used for tissue engineering for animal models. while decellularization of tissues such as bladder, heart valve, knee meniscus and tendon has been performed, there are a few reports for articular cartilage. in this study we aimed to develop a technique to decellularize bovine articular cartilage as a biological construc...
متن کاملConditioned medium derived from mesenchymal Stem cells regenerates’ defected articular cartilage
Background & Aims: One of cell- based technical issues associated with cartilage repair assay is delivering cells to the site of the parts where damage is created. Mesenchymal stem cells (MSCs) with their chondrogenic potential are ideal candidates for cartilage regeneration. High expression of cartilage hypertrophy markers by MSCs would result in apoptosis and ossification. This investigation ...
متن کاملMesenchymal Stem Cell Purification from the Articular Cartilage Cell Culture
Objective Articular cartilage as an avascular skeletal tissue possesses limited capacity to heal. On the other hand, it is believed that the regeneration capacity of each tissue is largely related to its stem cell contents. Little is known about the presence of mesenchymal stem cells in articular cartilage tissue. This subject is investigated in the present study. Materials and Methods Artic...
