Angiogenesis and Inflammatory Cell Infiltration in Lumbar Disc Herniation

Abstract: The results suggest that the vascular endothelial growth factor produced by the spindle-shaped cells acts to promote angiogenesis inside granulation tissue infiltrating the cartilage matrix, and that new blood vessels play an important role as a passage for macrophages into the degenerated matrix.

“…The duration of disc herniation is believed to affect significantly the extent of neovascularization around herniated ID fragments. Newly formed blood vessels were found to play an important role as a passage for infiltrating macrophages, resulting in the secretion of proteolytic enzymes such as MMPs [16]. Of note, up-regulation of MMP-9 mRNA expression was established in vitro in the process of neurogenesis and vascularization during embryonic tissue development [4].…”

“…The type of herniation (protrusion, extrusion or sequestration) together with age and duration of symptoms have been correlated to different degrees of molecular changes within the disc cells and its extracellular matrix [16]. In addition, serial magnetic resonance imaging (MRI) studies have documented the spontaneous resorption of non-operatively treated herniated discs [17,31].…”

“…A maior parte da literatura pertinente utiliza espécimes doentes, portanto sintomáticos, obtidos em cirurgias de hérnia discal (protrusão, extrusão e sequestro) 23,37,124,133,156 ; espondilólise/espondilolistese 28,39 ; escoliose 161 e cervicalgia/lombalgia (dissectomia) 22,123,153,164 . Trabalhos que relacionam indivíduos sintomáticos x assintomáticos admitindo esses últimos como controle normal, exibem um número menor desses espécimes, por serem de origem cadavérica 20,22,31,36 .…”
