Viabilidade de células do sistema nervoso central fetal no tratamento da lesão medular em ratos

Abstract: OBJETIVOS: Propor um modelo experimental de transplante de células do sistema nervoso fetal de ratos Wistar para o sítio de lesão medular de ratos adultos que permitisse sua sobrevivência e integração para possibilitar protocolos de pesquisa que identificarão outros fatores de regeneração e recuperação funcional pós trauma raquimedular. MÉTODOS: Vinte ratos adultos foram submetidos a laminectomia, e lesão de 5mm de hemimedula realizada com auxílio de microscópio óptico. Quinze deste ratos tiveram seu sítio de … Show more

“…In this study, the two heads of the laboratory of FMUSP, with 15 years of experience in the application of the scale and who published sereval papers in this line of research, were considered the gold standard in the evaluation. 15 , 16 The BBB scale involves difficulty in the assignment of scores. 14 A computer program was developed to help reduce the discrepancy of scores assigned to the same rat by different observers, in an attempt to bring the evaluation of a researcher with limited experience in the scale closer to that of researchers experienced in its application.…”

“…The two heads of the laboratory (AFC and GBS), with 15 years of experience in the application of the scale, initially evaluated the images of the 12 rats and, in mutual agreement, assigned a single score to each animal, based on the side of greater motor deficit or the side with the lowest score. The results of the two more experienced evaluators, with papers published on the subject of spinal cord injury, 15 , 16 were considered the gold standard in the evaluation and used as a reference.…”

“…Muitos estudos encontram-se em andamento em relação à regeneração do sistema nervoso central, com o uso de fatores neurotróficos, do enxerto de nervos periféricos associados ou não a fatores neurotróficos (Bregman et al (1997)), de anticorpos bloqueadores dos fatores inibitórios da regeneração, do enxerto de células do sistema nervoso central (Ramón-Cueto et al (1998)), e de células tronco (Nockels;Young (1992), Schwab;Bartholdi (1996), Amar;Levy (1999) e Cristante et al (2002)).…”
