The limited regenerative capacity of articular cartilage and deficiencies of current treatments have motivated the investigation of new repair technologies. In vitro cartilage generation using primary cell sources is limited by cell availability and expansion potential. Pluripotent stem cells possess the capacity for chondrocytic differentiation and extended expansion, providing a potential fut...
Mesenchymal stem cells (MSCs) play a critical role in cartilage tissue engineering. However, MSCs-derived chondrocytes or cartilage tissues are not stable and easily lose the cellular and cartilage phenotype during long-term culture in vitro or implantation in vivo. As a result, chondrocytes phenotypic instability can contribute to accelerated ossification. Thus, it is a big challenge to mainta...
Purpose: To isolate and purify unrestricted somatic stem cells from human umbilical cord blood and evaluation of their differentiation into chondrocyte in vitro.Materials and Methods: In this study cells from human umbilical cord blood were isolated and plated in flask. Colonies were performed after one week. To determine the kind of cells, 100000 cells were analysed with flowcytometry. Twenty ...
BACKGROUND Understanding the key elements of signaling of chondroprogenitor cells at the earliest steps of differentiation may substantially improve our opportunities for the application of mesenchymal stem cells in cartilage tissue engineering, which is a promising approach of regenerative therapy of joint diseases. Ion channels, membrane potential and Ca(2+)-signaling are important regulators...
Osteoarthritis (OA) is an age-related disease with poorly understood pathogenesis. Recent studies have demonstrated that miRNA might play a key role in OA initiation and development. We reviewed recent publications and elucidated the connection between miRNA and OA cartilage anabolic and catabolic signals, including four signaling pathways: TGF-β/Smads and BMPs signaling, associated with cartil...
background: osteoarthritis is one of the most common diseases in middle‑aged populations in the world and could become the fourth principal cause of disability by the year 2020. one of the critical properties for cartilage tissue engineering (te) is the ability of scaffolds to closely mimic the extracellular matrix and bond to the host tissue. therefore, te has been presented as a technique to ...
Differentiation of derived from in vitro-incubated adult human mesenchymal stem cells (MSCs), isolated bone marrow, cartilage and adipose tissue, respectively, by application appropriate incubation conditions, to osteoclasts, was investigated proved. The current results show the importance changes mitochondrial dynamics about differentiation male germ (spermatogonia) mature functional activity ...
Background and Objective: Various diseases and injuries can lead to loss cartilage tissue. Cartilage tissue engineering based on the use of stem cells which has provided a promising opportunity to repair damaged tissue. Recently, adipose-derived mesenchymal stem cells (ADSCs) have captured considerable scientific and clinic interest because of their easy access, rapid expansion in vitro...
