Secretome Dental Pulp Stem Cells have been proposed as a new alternative for wound burn. The aim of this study is to compare Secretome Dental Pulp Stem Cells and MEBO ointment against several fibroblasts and collagen in the healing process of superficial dermal burns. This study used a post-test only controlled group design by using 15 rats that were given superficial dermal burned wounds. Rats were divided into a negative control group of NaCl 0.9% (K1), a treatment group of MEBO (K2), and a treatment group of DPSCs-secretome (K3). Histopathology was done on the 5th, 14th, and 21st days post-induction wound burn. Network-prepared histopathology by colouring Messon Trichomes. Then, it was observed under a microscope with 200x magnification. Scoring in a way semi-qualitative for assessing fibroblasts and collagen. The total score of fibroblasts in the MEBO group was higher than the DPSCs-secretome group on day 5th. In comparison, the score for increasing the amount of collagen in the DPSCs-secretome group on days 5th and 14th was higher than the MEBO group. DPSCs-secretome has better effectiveness in increasing the amount of collagen but not better in increasing fibroblasts compared to MEBO.

Human epidermal growth factor receptor 2 (HER-2) is used as a marker for the diagnosis and prognosis of breast cancer. However, the molecular mechanisms involving HER2 in breast cancer require further study. Herein, we used the bioinformatics approaches to identify important pathways and hub genes in breast cancer affected by HER-2. The results showed that HER-2 is highly expressed in ovarian cancer and is closely related to the overall survival and progression-free survival of breast cancer. A total of 3014 downregulated genes and 4121 upregulated genes were identified under Gene Expression Omnibus (GEO) database with the GEO2R tool. Among them, the top 10 hub genes including CCNB1, KIF11, BUB1B, TOP2A, ASPM, MAD2L1, BUB1, RRM2, EGFR, and FN1 demonstrated by connectivity degree in the protein-protein interaction (PPI) network were screened out. In Kaplan–Meier plotter survival analysis, the overexpression of CCNB1, EGFR, MAD2L1, ASPM, and RRM2 were shown to be associated with an unfavourable prognosis in HER-2 positive breast cancer patients. In conclusion, we have identified important signalling pathways involving HER-2 that affect breast cancer. These findings could provide new insights outlining mechanisms involving HER-2 gene expression in breast cancer and provides a rationale for the novel treatment of breast cancer.

Full-thickness wound are areas damage of skin associated with loss of epidermis and dermis. The wound healing mechanism consists proliferation, migration and remodeling. Hypoxic conditional medium of mesenchymal stem cells (HMSCs-CM) contains lots of soluble molecules, such as protein growth factor and cytokine anti-inflammation. The soluble molecule of HMSCs-CM plays a critical role in wound healing by upregulation of VEGF and collagen synthesis. The objective of this study was to evaluate the effect of HMSCs-CM on VEGF and collagen concentrations in rats with incised wounds. The methods of this study were an experimental animal study with post-test only control group design was performed involving 24 Wistar rats. The rats were randomized into four groups consisting of sham, control and two treatment groups (gel of HMSCs-CM at doses of 200 μL and 400 μL). The VEGF levels and collagen density were analyses using ELISA assay and Masson-trichome specific staining, respectively. One-way ANOVA and Post Hoc LSD were used to analyses the data. The results of this study showed that a VEGF levels was significant increased on day 6 with doses-dependent manner. Interestingly, the VEGF levels gradual decrease on day 9. In addition, the decreased of VEGF levels on day 9 in this study in line with our findings in which we found there was a trend in the decreased of collagen density, it indicated the completion of remodeling phase and there has been an acceleration in wound healing. This study demonstrated that HMSCs-CM were able to regulate VEGF levels and collagen synthesis in accelerate wound healing. The role of HMSCs-CM stimulate cutaneous wound healing should be clarified further.Keywords: hypoxic conditional medium of mesenchymal stem cells (HMSCs-CM), vascular endothelial growth factor, collagen synthesis, paracrine factors
