Caracterización Histológica E Inmunocitoquímica de la Grasa Infrapatelar de Hoffa

Abstract

ResumenEl presente estudio tuvo como objetivo la caracterización histológica e inmunocitoquímica de la grasa infrapatelar de Hoffa (GIH) en 12 pacientes intervenidos por artroscopia, meningoplastia o remplazo de rodilla. Las fibras elásticas estuvieron presentes en la grasa infrapatelar con distribución unidireccional fascicular, se plantea una relación funcional en la biomecánicas del movimiento articular de la rodilla. Por otra parte las pruebas de inmunocitoquimica arrojaron marcaje positivo para vimentina, marcador de células del tejido conectivo; células mesenquimales y negativo para el resto de los anticuerpos estudiados. Palabras clave: grasa infrapatelar, biomecánicas, vimentina, inmunocitoquimica, fibras elásticas. Abstract Histological and immunohistochemical characterization of infrapatellar Hoffa's fatThis study aimed to histological and immunohistochemical characterization of infrapatellar fat Hoffa (GIH) in 12 patients undergoing arthroscopic, meningoplastia or knee replacement. Elastic fibers were present in the infrapatellar fat with unidirectional fascicular distribution, we propose a functional relationship in the biomechanics of the knee joint movement. Moreover Immunocytochemistry tests yielded positive staining for vimentin, a marker for connective tissue cells, mesenchymal cells and negative for other studied antibodies.

“…Afterwards, they were passed through alcohols at increasing concentrations and then with propylene oxide. They were then infiltrated with histological resin and polymerized at 60 °C to be cut with a glass blade in an ultra-microtome, stained with toluidine blue, and H&E mounted (11) (12), and observed (13).…”
