Embryonic skeletal development is the result of programmed differentiation and morphogenesis of the embryonic mesoderm. This review summarizes recent cellular and molecular findings on the mechanisms underlying development of the cranial, axial, appendicular skeletal components. Specifically, the identities and activities of patterning and morphogenetic genes are presented, as well as the regul...
Cultured embryonic and adult skeletal muscle cells have a number of different uses. The micro-dissected explants technique described in this chapter is a robust and reliable method for isolating relatively large numbers of proliferative skeletal muscle cells from juvenile, adult or embryonic muscles as a source of skeletal muscle stem cells. The authors have used micro-dissected explant culture...
BACKGROUND The declining myogenic potential of aged skeletal muscle is multifactorial. Insufficient satellite cell activity is one factor in this process. Notch and Wnt signaling are involved in various biological processes including orchestrating satellite cell activity within skeletal muscle. These pathways become dysfunctional during the aging process and may contribute to the poor skeletal ...
background: the purpose of present study was to investigate whether sphingosine 1-phosphate (s1p) levels and its receptors gene expressions are correlated with myod and myogenin following resistance training. materials and methods: 24 eight-week-old male wistar rats (190-250 gr) were assigned randomly to a control (n = 12) or training (n = 12) group. rats climbed a resistance training ladder wi...
AMP-activated protein kinase (AMPK) activation by AICAR (5-amino-imidazole carboxamide riboside) is correlated with increased glucose transport in rodent skeletal muscle via an insulin-independent pathway. We determined in vitro effects of insulin and/or AICAR exposure on glucose transport and cell-surface GLUT4 content in skeletal muscle from nondiabetic men and men with type 2 diabetes. AICAR...
We propose a mathematic model of muscle cell membrane based on thin-walled elastic rod theory. A deformation occurs in rodents’ skeletal and cardiac cells during a period of antiorthostatic suspension. We carried out a quantitative evaluation of the deformation using this model. The calculations showed the deformation in cardiac cells to be greater than in skeletal ones. This data corresponds t...
The process of skeletogenesis during embryonic development involves sor cells, all taking place in a highly dynamic environment. The overall and pressures that are hypothesized development. However, details of these mechanical cues are not well understood, ments that could address these of early skeletal development in vitro. To strain on embryonic skeletal precursor cells in micromass culture....
WHAT IS RHABDOMYOSARCOMA? There are two kinds of muscle cells in the body: smooth muscle cells and skeletal muscle cells. Smooth muscles control involuntary activities; skeletal muscles control voluntary activities. Rhabdomyosarcoma (RMS) is a malignant tumor ("cancer") that arises from a normal skeletal muscle cell. Not very much is known about why normal skeletal muscle cells become cancerous...
Multipotent Pax3-positive (Pax3(+)) cells in the somites give rise to skeletal muscle and to cells of the vasculature. We had previously proposed that this cell-fate choice depends on the equilibrium between Pax3 and Foxc2 expression. In this study, we report that the Notch pathway promotes vascular versus skeletal muscle cell fates. Overactivating the Notch pathway specifically in Pax3(+) prog...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
