A terapia celular no tratamento da isquemia crítica dos membros inferiores

Abstract: Os autores fazem um histórico sobre as pesquisas com células-tronco embrionárias e do cordão umbilical, suas respectivas vantagens e desvantagens. Seguem com as discussões sobre células-tronco adultas, sua definição, histórico, fontes e participação nos processos de regeneração tecidual, particularmente no endotélio. Ressaltam a importância de fatores que mobilizam as células-tronco adultas a partir da medula óssea: citocinas, angiopoietinas e outros fatores de crescimento. As células-tronco adultas mobilizam-… Show more

“…ASCs are believed to remain quiescent in the tissues in which they are found until they are activated by diseases, tumors, or injuries. In addition, these cells replace cells of the organism throughout life by the release of progenitor cells into the blood circulation, which migrate to the sites where they are needed [13].…”

“…7 Mesenchymal stem cells can also be obtained by hematopoietic recovery by separation of peripheral blood and can potentially be increased in number after mobilization by specific growth hormones (granulocyte-colony stimulating factor -G-CSF). 1 In view of the diverse range of situations in which current medicine suffers from limitations, application of cell engineering could be a viable option for treatments to regenerate or substitute tissues. Such techniques are considered new domains in translational medicine, involving cell therapy and tissue engineering, which have emerged as innovative proposals within a panorama in which medicine will be applied in a patient-directed manner.…”

“…Hoje o grande número de pesquisas de células-tronco têm se desenvolvido com mais intensidade com células-tronco adultas (ZAGO 2002;GRONTHOS et al, 2002;KORBLING, ESTROV, 2003;ARAÚJO et al, 2005 No entanto, os dados ainda são preliminares e insuficientes para avaliar a eficácia da administração destas na restauração do tecido encefálico lesionado, confirmando assim, uma resposta funcional e eficiente. …”
