Características de cultivos celulares primarios derivados de Sarconesiopsis magellanica (Le Guillou, 1842) (Diptera: Calliphoridae)

Abstract

The present work was aimed at obtaining and characterizing cell cultures from Sarconesiopsis magellanica embryonic tissue (Diptera: Calliphoridae). This fly is important by its applications in the establishment of post-mortem interval. This study evaluated seven culture medium (Grace, Grace/L15, MM, VP12, MM/VP12, Eagle and Schneider), supplemented with 20% fetal bovine serum. The adhesion, cell growth and proliferation were observed in L15 medium, Schneider and Grace/L15, achieving better results in the last two. The confluent monolayer was present in an average of twelve days after that the explants were made. The growth pattern of the primary cultures showed the presence of vesicles with cells adhering to its walls, which helped to form a confluent monolayer. The predominant cell morphology in monolayer correspond to fibroblastoid a lesser extent to epithelioid, showing the first similar to nerve cells. Additionally, there was in the early days of primary cultures, especially in some clusters of cells, contractile movement, similar to those made by muscle cells. These primary cell cultures derived from S. magellanica represent potentially suitable substrates for further testing of susceptibility to infection with arboviruses and parasites.
