ABSTRACT
The hexachlorophene (HCP) is a highly lipophilic chlorinated bisphenol present in hygienic and dermatological products. The HCP accumulates preferentially in adipose tissue that is a privileged source of mesenchymal stem cells (MSCs). The evaluation of the potential effects of HCP on MSCs is important for their medical application. Here we examined the effects of HCP on murine adipose tissue-derived stem cells (ADSCs) and human umbilical cord-derived stem cells (UCSCs) in cell culture. We found that 10−4 and 10−5 M HCP inhibits proliferation, osteogenesis and increases apoptosis of ADSCs and UCSCs. While the effect of HCP on proliferation and differentiation potential of these two cell lines was similar, the UCSCs appeared much more resistant to HCP-induced apoptosis than ADSCs. These results suggest that the adipose tissue-derived ADSCs have higher sensitive for HCP than umbilical cord-derived UCSCs and indicate that the umbilical cord can be a preferable source of MSCs for prospective medical applications in the future.

Foi verificada a ação tóxica do hexaclorofeno na concentração de 5%, em cobaias. Os testes foram realizados sobre a pele da região ventral, depilada e sem depilar. A irritação primária observada após 45 dias da aplicação incluía rachaduras na pele. Observou-se que gerações posteriores eram mais sensíveis ao hexaclorofeno. O efeito tóxico da substância absorvida pela pele estendeu-se também aos órgãos internos dos animais sob teste. As cobaias em estudo foram comparadas com grupo controle (AU).
