Secretome profile of TNF-α-induced human umbilical cord mesenchymal stem cells unveils biological processes relevant to skin wound healing.
Aim: To profile and study the proteins responsible for the beneficial effect of the TNF-α-induced human umbilical cord mesenchymal stem cells (hUCMSCs) secretome in wound healing. Methods: The hUCMSCs secretome was generated with (induced) or without (uninduced) TNF-α and was subsequently analyzed by liquid chromatography-mass spectrometry, immunoassay and in vitro scratch assay. Results: Proteomic analysis revealed approximately 260 proteins, including 51 and 55 unique proteins in the induced and uninduced secretomes, respectively. Gene ontology analysis disclosed that differential proteins in the induced secretome mainly involved inflammation-related terms. The induced secretome, consisting of higher levels of FGFb, VEGF, PDGF and IL-6, significantly accelerated wound closure and enhanced MMP-13 secretion in HaCaT keratinocytes. Conclusion: The secretome from induced hUCMSCs includes factors that promote wound closure.
期刊介绍：
Regenerative medicine replaces or regenerates human cells, tissue or organs, to restore or establish normal function*. Since 2006, Regenerative Medicine has been at the forefront of publishing the very best papers and reviews covering the entire regenerative medicine sector. The journal focusses on the entire spectrum of approaches to regenerative medicine, including small molecule drugs, biologics, biomaterials and tissue engineering, and cell and gene therapies – it’s all about regeneration and not a specific platform technology. The journal’s scope encompasses all aspects of the sector ranging from discovery research, through to clinical development, through to commercialization. Regenerative Medicine uniquely supports this important area of biomedical science and healthcare by providing a peer-reviewed journal totally committed to publishing the very best regenerative medicine research, clinical translation and commercialization.
Regenerative Medicine provides a specialist forum to address the important challenges and advances in regenerative medicine, delivering this essential information in concise, clear and attractive article formats – vital to a rapidly growing, multidisciplinary and increasingly time-constrained community.
Despite substantial developments in our knowledge and understanding of regeneration, the field is still in its infancy. However, progress is accelerating. The next few decades will see the discovery and development of transformative therapies for patients, and in some cases, even cures. Regenerative Medicine will continue to provide a critical overview of these advances as they progress, undergo clinical trials, and eventually become mainstream medicine.
