The objective of this study was to assess the efficacy of a cell-containing wound dressing based on fibroblasts in hydroxyethylcellulose (HEC) gel for the local treatment of deep partial-thickness and/or full-thickness skin burns in an animal model. The rats (male Wistar, n = 100) were subjected to a full-thickness thermal burn (16 cm). Radical necrectomy was performed one day after the burn.

This study aimed to characterize the expression profiles of TEs in embryonic stem cells (ESCs), cancer cell lines, tumor tissues, and the tumor microenvironment (TME). We observed similarities in TE expression profiles between cancer cells and ESCs, suggesting potential parallels in regulatory mechanisms.

To address this, we conducted a comparative analysis of mesenchymal cell primary cultures from 6 human sources, including osteoblast-like cells from the adult femur, adipose-derived stem cells, Wharton's jelly-derived mesenchymal cells, gingival fibroblasts, dental pulp stem cells, and periodontal ligament stem cells. We analyzed these cells' secretome, proteome, and transcriptome under standard and osteogenic cultivation conditions.

Multiple myeloma (MM) is associated with bone resorption. During disease progression, MSCs acquire a tumor-associated phenotype, losing their osteogenic potential.

However, the functionality of the transcription remains obscure. Studies in this area have been hampered by the absence of a gapless genome assembly.
