Cultivo celular in vitro: importância para a pesquisa biomédica e dimensão da problemática de autenticação de linhagens celulares

Experimental models composed by human and animal cell lines are simplified and informative, allowing them to be widely used for biomedical research. Most laboratories that use in vitro cultivated cells maintain a variation of cell lines stored and cultivated. Therefore, misidentification and cross-contamination events can happen during cell lines handling. This problem can generate a repertoire of dubious results and papers, which may prejudice biomedical research. Recently it was created the International Cell Line Authentication Committee (ICLAC), which aims to spread knowledge about cross-contamination and misidentification of in vitro cell lines. Despite of the efforts spent trying to aware scientific community about the importance of the correct identification of cells, the number of papers based on misidentified cell lines it´s still worrying, compromising the reliability of out coming results and conclusions regarding them. The present study aims to analyze and discuss the main advantages and limitations of eukaryote in vitro cell lines use, characterizing the cell lines authentication problems. Therefore, compilation and critical analyses of literature data was realized, aiming to improve the understanding about this subject. Based on information about 445 cell lines with issues published by ICLAC it´s clear that contamination in human cell lines represented 89,2 % of mentioned problems. HeLa cell line was the responsible for most contamination, especially in 92 normal tissue cell lines, representing 44,6% of the contamination. These results reinforce the importance of periodic maintenance of cell lines cultures by labs and implementation of authentication methods as polymorphic STRs, besides obtaining cell lines from reliable sources and cell banks

Avaliação dos efeitos de aloe-emodin em células uroteliais imortalizadas e neoplásicas cultivadas in vitro

Aloe vera (Aloe barbadensis Miller), popularly known in Brazil as babosa, has a long history of use as medicinal plant for different therapeutic purposes. The components of the plant extract are present in various products of human use, mainly for nutritional and cosmetics purposes. However, some studies suggest that this extract might also have carcinogenic activity. The aloe vera extract is a complex mixture of bioactive compounds. The study of isolated compounds may contribute to elucidate contradictory results about the effects related to the consumption of the plant, as well as their mechanisms of action. One of the most important compound from Aloe vera is aloe-emodin, which is a secondary metabolite generated in the intestinal tract. Putative antimicrobial and antitumor effects were previously attributed to aloe-emodin. Although the exposure of urothelial cells to aloe-emodin was already reported in the literature, only one study showed its effects on urothelial cells, suggesting that aloe-emodin inhibits the viability of T24 cancer cells due to apoptosis induction. Since there is no sufficient information about the effects of aloe-emodin on urothelial cells, and low efficiency in the treatment of bladder cancer currently, the present study aims to evaluate the hypothesis that the treatment with aloe-emodin could impact the behavior of other urothelial cell lines in vitro. Therefore, the in vitro IC50 exposure of aloe-emodin to human immortalized neoplastic urothelial cells will be determinated in order to verify possible differences in the behavior of urothelial cells in vitro treated with aloe-emodin in comparison with untreated cells. Furthermore, differences between cell lines will be also evaluated
