  • Title: Arterial wall neovascularization induced by glycerol.
    Author: Díaz-Flores L, Madrid JF, Gutiérrez R, Valladares F, Díaz M, Varela H, Díaz-Flores L.
    Journal: Histol Histopathol; 2001 Oct; 16(4):1175-81. PubMed ID: 11642737.
    Abstract:
    An intense and significant neovascularization, with numerous capillaries growing into the media layer of the rat femoral artery, was demonstrated when glycerol was administered into the interstitium between the femoral vein and the femoral artery. The maximum microvascularization was observed at days 7 and 9 after glycerol administration. Afterwards, involution of the majority of the newly-formed microvessels in the arterial wall occurred. Other substances containing glycerol in their molecules, such as triacetyl-glycerol and tributyril-glycerol, failed to produce significant neovascularization in the media layer of the femoral artery. Neovascularization of the arterial wall was preceded by a considerable decrease in the number of the smooth muscle cells, which experienced apoptosis and necrobiosis, disappearing in extense areas of the arterial segment affected by glycerol. Coinciding with neovascularization and microvascular involution, repopulation of the media layer by smooth muscle cells was observed.
