"Influência da composição de carreador biodegradável na viabilidade do implante de células mesenquimais indiferenciadas do tecido adiposo humano" / Influence of scaffold composition in the viability of implantation of human adipose derived undifferentiated mesenchymal cellsIsa Dietrich 09 December 2004 (has links)
Células mesenquimais indiferenciadas humanas foram obtidas por digestão enzimática e centrifugação do produto de lipoaspiração, expandidas in vitro, e implantadas no tecido subcutâneo de camundongos atímicos. No grupo I, cada animal recebeu o implante de uma membrana de 0,25cm2 de ácido glicólico e carbonato de trimetileno semeada com 1 x 106 destas células .No grupo II, cada um recebeu a injeção de 0,2ml de gel de ácido hialurônico reticulado contendo o mesmo número destas células. Com três semanas de implante, células humanas e vasos foram identificados nos dois carreadores. Entretanto, com oito semanas, somente no gel de ácido hialurônico as células humanas e os vasos estavam presentes / Human undifferentiated mesenchymal cells were obtained by enzymatic digestion and centrifugation of the product of liposuction. These cells were expanded, in vitro, and implanted subcutaneously in athymic mice. In group I, each animal received the implant of a 0,25cm2 membrane of glycolic acid and trimethylene carbonate, seeded with 1 x 106 of these cells. In group II, each one received 0,2 ml of cross-linked hyaluronic acid gel containing the same amount of these cells. With three weeks of implantation, human cells and vessels were identified in both carriers. However, with eight weeks of implantation, only in hyaluronic acid gel human cells and vessels were present
