Human dermal fibroblasts (HDF) termasuk sel mesenchymal yang diisolasi dari lapisan dermis kulit. HDF berpotensi digunakan untuk pengobatan penyembuhan luka berdasarkan pengobatan regeneratif. Peningkatan konsentrasi glukosa dapat merusak fungsi sel dan menghambat terapi penyembuhan luka. Penelitian ini dilakukan untuk mengkaji pengaruh glukosa tinggi pada proliferasi, migrasi dan ekspresi gen OCT-4 sel HDF sebagai model penyembuhan luka diabetes in vitro. Pada penelitian eksperimental ini, fibroblast diisolasi dari kulit setelah sirkumsisi, kemudian ditumbuhkan dalam medium Minimal Essential Medium (DMEM) Dulbecco lengkap dengan serum 10%. Untuk menguji efek glukosa tinggi pada proliferasi sel HDF dilakukan dengan uji CCK-8. Migrasi sel HDF dievaluasi menggunakan uji scratch-assay. RT-PCR digunakan untuk menentukan ekspresi gen OCT-4.  Hasilnya menunjukkan bahwa glukosa tinggi (25 mM-50 mM) meningkatkan kemampuan proliferasi dan migrasi sel HDF. Efek glukosa tinggi tergantung pada dosis. Perlakuan glukosa pada dosis 75 mM akan menghambat kemampuan pertumbuhan HDF. Ekspresi gen OCT-4 meningkat secara bermakna pada pemberian glukosa dosis 25-50 mM. Hasil penelitian ini memberikan dasar untuk pengembangan terapi dalam kondisi diabetes bahwa terapi sel HDF dapat meningkatkan penyembuhan luka meskipun dalam kondisi glukosa tinggi.

This first-attempt study tended to inspect the cytotoxic effects of montmorillonite (MMT) or 0.01 N phosphoric acid treated MMT supplemented with L-ascorbic acid (LAA) upon human dermal fibroblasts for possible applications. Light micrographs of human dermal fibroblast cell cultures revealed that more dense black spots in larger sizes were observed when higher levels of MMT were supplemented into the fibroblast culture, indicating that more dermal fibroblasts were covered by MMT particles. Compared with the supplementation of LAA alone, this study selected mitochondrial dehydrogenase activity (MTT) assay as an indicator bioreaction to show possible cytotoxic (or allergic) responses upon human dermal fibroblasts in vitro when LAA/acid-treated MMT composites were added. Statistical analysis showed that LAA augmented with either MMT or 0.01 N phosphoric-acid-treated MMT provoked insignificant cytotoxic responses to human dermal fibroblasts. Thus, an augmentation of MMT or 0.01 N phosphoric-acid-treated MMT to LAA should be biologically feasible for possible skin applications according to this human dermal fibroblasts model.

Our previous study evaluated the antioxidant activities of sulfated polysaccharides from Celluclast-assisted extract of Hizikia fusiforme (HFPS) in vitro in Vero cells and in vivo in zebrafish. The results showed that HFPS possesses strong antioxidant activity and suggested the potential photo-protective activities of HFPS. Hence, in the present study, we investigated the protective effects of HFPS against ultraviolet (UV) B-induced skin damage in vitro in human dermal fibroblasts (HDF cells). The results indicate that HFPS significantly reduced intracellular reactive oxygen species (ROS) level and improved the viability of UVB-irradiated HDF cells in a dose-dependent manner. Furthermore, HFPS significantly inhibited intracellular collagenase and elastase activities, remarkably protected collagen synthesis, and reduced matrix metalloproteinases (MMPs) expression by regulating nuclear factor kappa B (NF-κB), activator protein 1 (AP-1), and mitogen-activated protein kinases (MAPKs) signaling pathways in UVB-irradiated HDF cells. These results suggest that HFPS possesses strong UV protective effect, and can be a potential ingredient in the pharmaceutical and cosmetic industries.

Background. The antimicrobial activity and effects of a phytocomplex consisting of Tropaeolum flos (T) and Salviae folium (S) extracts on the cytokine levels and transcription factors on dermal fibroblast BJ exposed to bacterial lipopolysaccharides were examined. Methods. In order to select the most optimal combination ratio of the two extracts for using in vitro, the physicochemical characterization of vegetal extract mixtures was performed and the antioxidant and antibacterial activities were evaluated on five different formulations of T : S, namely, 1 : 1, 1 : 2, 2 : 1, 3 : 1, and 1 : 3. The best combination of bioactive compounds with regard to antioxidant and antibacterial activities (T : S 1 : 2) was selected for in vitro evaluation of the anti-inflammatory effect. Human dermal fibroblast BJ cells were treated with two doses of the extract mixture and then exposed to bacterial lipopolysaccharides (LPS). The levels of the cytokines involved in inflammatory response, namely, interleukin- (IL-) 6, tumor necrosis factor- (TNF-) α, IL-31, and IL-33, were quantified by ELISA, and the expression of transcription factors, namely, signal transducer and activator of transcription (STAT) 3, nuclear factor kappa B (NFκB), and phosphorylated NFκB (pNFκB), were evaluated by western blot analysis. Results. The results have shown that the mixture of T : S 1 : 2 exhibited significant antibacterial effects on Staphylococcus aureus ATCC 25923. LPS exposure increased the cytokine levels in BJ cells and enhanced the NFκB expression. The pretreatment of BF cells exposed to LPS with the two doses of the extract mixture markedly inhibited the increase of IL-33 and TNF-α levels and amplified the NFκB expression and its activation, especially with the high dose. The low doses of the extract reduced NFκB expression but increased its activation. Conclusions. These experimental findings suggest that the mixture of T : S 1 : 2 can exert some protection against bacterial infections and inflammation induced by LPS in BJ cells being a good therapeutic option in related conditions associated with inflammation.

We describe here the preparation of poly(caprolactone) (PCL)-chitin nanofibrous mats by electrospinning from a blended solution of PCL and chitin dissolved in a cosolvent, 1,1,1,3,3,3-hexafluoro-2-propanol and trifluoroacetic acid. Scanning electron microscopy showed that the neutralized PCL-chitin nanofibrous mats were morphologically stable, with a mean diameter of340.5±2.6 nm, compared with a diameter of524.2±12.1 nm for PCL mats. The nanofibrous mats showed decreased water contact angles as the proportion of chitin increased. However, the tensile properties of nanofibrous mats containing30~50% (wt/wt) chitin were enhanced compared with PCL-only mats.In vitrostudies showed that the viability of human dermal fibroblasts (HDFs) for up to 7 days in culture was higher on composite (OD value:1.42±0.09) than on PCL-only (0.51±0.14) nanofibrous mats, with viability correlated with chitin concentration. Together, our results suggest that PCL-chitin nanofibrous mats can be used as an implantable substrate to modulate HDF viability in tissue engineering.
