Effect of cyclosporin A (CsA) in a therapeutic concentration, on the expression of cytochrome P450 genes (), was investigated in normal human dermal fibroblast cells. The expression of 57 genes, encoding cytochrome P450 isoforms, was estimated using the microarray method. Amongst 396 normalized fluorescence signals related to cytochrome P450 activity, only 91 were strictly connected to and were analyzed using two methods: a self-organizing feature map of artificial neural networks and typical statistical analysis with significance level at ≤ 0.05. Comparing the samples from fibroblasts cultured with CsA and those cultured without, up-regulated changes of , , , , and down-regulated gene expression were observed. The mRNAs with increased changes were in the same neuron of the self-organizing feature map. All distinguished encode monooxygenases, which plays an important role in steroids biosynthesis and metabolism. Based on the obtained results, we can conclude that CsA in therapeutic concentration changes the expression profile of in human dermal fibroblasts, especially affecting genes linked to steroids synthesis and/or metabolism. It shows the potential mechanism of action of CsA in human dermal fibroblast cells.

Background: Several studies have suggested that adult human dermal fibroblasts (HDFa) may be a potential alternative source to mesenchymal stem cells for cell therapies. This study aims to characterize HDFa, adipose-derived stem cells (ADMSCs) and dental pulp stem cells (DPSCs) to investigate their proliferation, differentiation potential, mitochondrial respiration, and metabolomic profile. We identified molecules and characteristics that would differentiate MSCs from different sources or confirm their uniformity.

Background: Despite the advancements of pharmacological treatments and gauze dressings in the field of skin wound healing, these methods present numerous limitations. Therefore, developing a multifunctional material capable of efficiently promoting skin wound healing is particularly crucial.
Methods: Citric acid (CA)-modified chitosan (CS) loaded with Shikonin (SK) (CA-CS-SK) hydrogel was prepared via the freeze-thaw method.

Plantar melanomas present unique diagnostic and surgical challenges owing to substantial regional variations in skin thickness. Although the Breslow thickness remains the primary criterion for staging and surgical excision, its application on plantar melanoma is complicated by the inherent thickness of the glabrous plantar epidermis, which may lead to tumor depth overestimation. Accurate assessment of plantar skin thickness is essential for optimizing staging accuracy and refining surgical margins.

Conventional radiotherapy based on X rays is used to treat more than 50% of cancers. Although effective, radiotherapy can damage healthy tissues around the tumor due to the X-ray dose deposition profile, as well as the safety margin needed to compensate for dose uncertainties. A notable side effect is cellular senescence, characterized by the cessation of cell division while maintaining metabolic activity and promoting the secretion of various components, called the senescence-associated secretory phenotype.

This study aimed to develop an acellular dermal matrix derived from tilapia skin and evaluate its potential as a bioscaffold for skin wound repair. Structural and compositional changes before and after decellularisation were assessed through histological staining, electron microscopy and immunological analysis. The matrix exhibited low immunogenicity, preserved extracellular matrix architecture and retained key bioactive components.
