However, clear management standards and verification systems for the use of exosomes as drugs are still being developed. In this study, the effectiveness of exosomes as drug candidates was verified after production in accordance with the guidelines for donor suitability, cell bank construction of cell therapy drugs, and quality control of extracellular vesicles published by the Korean Ministry of Food and Drug Safety (KMFDS). <b>Methods:</b> Basic characteristics were identified using umbilical cord blood mesenchymal stem cells (UCBMSCs)-released exosomes produced in accordance with the three guidelines, and internal component analysis of proteins, lipids, and nucleic acids was performed. In addition, various types of <i>in vitro</i> and <i>in vivo</i> experiments confirmed the skin tissue regeneration efficacy of exosomes. <b>Results:</b> In addition, treatment of two types of skin cells (dermal fibroblast and keratinocyte) with exosomes resulted in a statistically significant increase in the proliferation and migration of skin cells and inhibition of the secretion of pro-inflammatory substances in an inflammatory environment. In an animal model of wound injury, exosome treatment accelerated the wound healing process. These <i>in vitro</i> and <i>in vivo</i> experiments confirm that UCBMSCs-released exosomes have tissue regeneration and inflammation suppression properties. <b>Conclusions:</b> This study presents the processes and quality control items that can produce exosomes as drugs in good manufacturing practice facilities and shows the possibility of developing drugs for various diseases based on the inherent efficacy of UCBMSCs-released exosomes.

This study investigates the potential role of the Solute Carrier Organic Anion Transporter Polypeptide 1A2 (OATP1A2) in PTX transport using computational approaches. We employed computational modeling, molecular docking, and molecular dynamics (MD) simulations to elucidate the structural dynamics of OATP1A2 and its interaction with PTX. The OATP1A2 structure was modeled using Phyre2, validated, and refined.

The ligand shifted approximately 5.4 Å towards the extracellular side from its initial binding position. This observation suggests a more complex transport mechanism than initially anticipated. The protein-ligand complex exhibited stability throughout the simulation, with notable conformational changes.

Recent advancements in regenerative medicine highlight the potential of Adipose Tissue-Derived Stem Cells (ADSCs), particularly through their secretome, which includes mediators, bioactive molecules, and extracellular vesicles (EVs). Notably, exosomes, a subset of EVs, facilitate cell-to-cell communication and, when derived from ADSCs, exhibit anti-inflammatory properties and contribute to tissue regeneration. In this work, we aim to characterize the content of exosomes derived from feline ADSCs (fADSCs) to elucidate their mechanisms of action on recipient cells and assess their therapeutic potential for FIC. Exosomes were isolated from fADSCs and their microRNA (miRNA) content sequenced using Illumina technology.
