Retroviral gene transduction in limb bud micromass cultures.
1. Introduction Since Solursh and his coworkers set up the limb bud micromass cultures in 1977 (1), this procedure has become a major model to analyze cellular and molecular event involved in chondrogenesis (2–7). Recently, RCAS retroviral vectors have been developed that can infect chicken embryos in ovo. These have advanced our understanding in limb bud patterning remarkably (8). Here we desc...
متن کاملeffects of low frequency electromagnetic fields on chondrogenesis and osteogenesis of embryonic chick limb bud
introduction: depending on mode, intensity and length of application, and stage of development, the low-frequency electromagnetic fields (lfes) can induce a wide variety of biological effects in organisms. the chick limb bud is a powerful experimental system for study pattern formation in vertebrate embryo. the aim of this study was to examine the effects of an application lfes (50hz, 50g) on c...
متن کاملAdhesion molecules in skeletogenesis: II. Neural cell adhesion molecules mediate precartilaginous mesenchymal condensations and enhance chondrogenesis.
Neural cell adhesion molecules (NCAM) was expressed transiently by mesenchymal cells in precartilaginous condensations of the embryonic chicken limb but was lost upon differentiation into cartilage. Consequently, NCAM was present in the periphery of the limb anlagen but was absent in the cartilaginous center of the growing limb. To determine NCAM function in limb bud chondrogenesis we incubated...
متن کاملWhich Culture System Is better for Chondrogenesis of Adipose-Derived Stem Cells ; Pellet or Micromass?
Background and Aims: The current study was conducted to compare the expression levels of collagen type Π and X during chondrogenesis of human adipose-derived mesenchymal stem cells (hADMSCs) pellet and micromass cultures. Materials and Methods: Extracted hADMSCs were cultured until three passages and then transferred to pellet and micromass cultures in the experimental groups of day 7 and day...
متن کاملExpression and functional involvement of N-cadherin in embryonic limb chondrogenesis.
Cell adhesion molecules have been shown to be important mediators of morphogenesis and pattern formation. In this study, we have shown that N-cadherin is expressed in a specific spatiotemporal manner in the developing limb bud during chondrogenesis in vivo and in cultured limb mesenchyme in vitro. The time period of maximal expression of N-cadherin corresponds to the period of active cellular c...
