Bone-marrow stromal cells can differentiate into multiple mesenchymal lineages including cartilage and bone. When these cells are seeded in high-density 'pellet culture', they undergo chondrogenesis and form a tissue that is morphologically and biochemically defined as cartilage. Here, we show that dual chondro-osteogenic differentiation can be obtained in the same micromass culture of human bo...
Objective(s):Osteoarthritis (OA) is globally one of the most common diseases from the middle age onwards. Cartilage is an avascular tissue therefore it cannot be repaired in the body. Conservative treatments have failed as a good remedy and cell therapy as a decisive cure is needed. One of the best and easily accessible cell sources for this purpose is adipose-derived stem cells which can be di...
This study aimed to investigate the chondrogenic transdifferentiation potential of human dermal fibroblasts (DFs) by stimulation with cartilage-derived morphogenetic protein 1 (CDMP1). Using CDMP1 (100 ng/mL) we induced human DFs at passage 5 in both monolayer and micromass culture. Chondrogenic-specific markers were detected via immunochemistry, reverse transcription-polymerase chain reaction,...
Cartilage is an avascular tissue with only a limited potential to heal and chondrocytes in vitro have poor proliferative capacity. Recently, adipose-derived stromal cells (ASC) have demonstrated a great potential for application to tissue engineering due to their ability to differentiate into cartilage, bone, and fat. In this study, we have utilized a high density three-dimensional (3D) microma...
The shapes of homologous skeletal elements in the vertebrate forelimb and hindlimb are distinct, with each element exquisitely adapted to their divergent functions. Many of the signals and signalling pathways responsible for patterning the developing limb bud are common to both forelimb and hindlimb. How disparate morphologies are generated from common signalling inputs during limb development ...
A method of culturing early (13-day) rat embryo neural cells is described. Undifferentiated neural epithelium is disaggregated and cultured in small discrete islands. Cells that destined to differentiate as neurons actively segregate from the other cells in the island and aggregate together into small clumps. Other cells flatten and attach to the substrate and resemble typical fibroblasts throu...

introduction: the aim of this study was to differentiate human mesenchymal stem cells (hmscs) into cartilage in a micromass culture system and study of their structure by light and electron microscopy. material and methods: human bone marrow cells obtained from volunteer patients were plated in 75-cm2 flasks and their mscs were expanded through several sub-cultures. the passage 4 cells were use...
