The multifunctional role of fibroblasts during wound healing in Hirudo medicinalis (Annelida, Hirudinea)
No full textExtracellular matrix components play a key role during the angiogenic process for a correct development of blood vessels: fibroblasts are the main cell type involved in the regulation of ECM protein production. In this study we characterize H. medicinalis fibroblasts and demonstrate that they take part to the regulation of angiogenesis that occurs during wound healing process. Massive proliferation and phenotypic modification are two distinctive markers of fibroblast activation. These cells, that are usually responsible for collagen production and function as an energy reservoir, are recruited during wound healing to form a collagen scaffold through a direct mechanic action and through secretion of specific proteoglycans. In addition we show that the activity of fibroblasts is modulated by EGF, a growth factor involved in wound healing in vertebrates. The formation of bundles of collagen fibrils by fibroblasts is fundamental for the development and migration of new blood vessels in lesioned areas during wound repair: administration of lovastatin in explanted leeches affects fibroblasts, damages collagen "scaffold" and indirectly causes the reduction of neo-capillary formation
Summary: kinematical properties and dynamical ages of extended halos
No full textIn this talk, I will provide a summary of the Sexten CfA``Light in the suburb’’ workshop with the focus on the kinematics of stellar halos. I will start with an historical perspective from Alan Dressler’s 1979 work on the velocity dispersion profile of the cD galaxy NGC 6166. I will then describe how halos make the difference in ICL, BCGs and early-type galaxies. Next I explore the links among different galaxy components and the distribution of orbits in the outer halos. I will address the way in which the different kinematics of independent tracers (PNe, red/blue GCs) can provide information on the progenitors of the halo stars. I will conclude with different examples of dynamical status and ages of stellar halos
