Introduction:
The present work aimed to assess the effect of bacterial cellulose (BC) from Acetobacter xylinum on some functions of peritoneal macrophages.
Materials And Methods:
Mice peritoneal macrophages were lavaged and co-cultured with various concentrations of BC in microtiter plate. Viability of macrophages was determined by MTT assay. Nitric oxide (NO) amount was detected in culture supernatants of macrophages by Griess reagent and cytotoxicity effect of culture supernatants on WEHI-164 cells as tumor necrosis factor α (TNF-α) bioassay were done.
Results:
MTT assay for stimulated macrophages was not different (p = 0.486) and amount of NO production in all doses was the same as unstimulated control macrophages (p = 0.057). Supernatant of macrophages stimulated with 0.01 mg/mL of BC had cytotoxic effect on WEHI-164 fibrosarcoma cells (p = 0.040).
Conclusion:
In this study, we showed that BC had no effect on macrophages viability and amount of NO production. BC suppressed the release of TNF-α from macrophages innate immune cells as indication of beneficial effect on wound healing. This data and further studies would imply use of this biomaterial for more applications.
