Abstract

The key to surviving severe burns is rapid burn wound excision and closure, yet extensive wounds often surpass natural healing capacity. Alternative treatments, such as synthetic skin substitutes, have not emerged as a standard, optimal solution. Stem cell therapies, especially using allogenic sources, show promise in enhancing wound repair. Induced mesenchymal stem cells (iMSCs) have demonstrated vast possibilities to overcome traditional stem cell therapy limitations. This study utilized Cord tissue-derived iMSCs (CT-iMSCs) incorporated into well-established epidermal-dermal substitutes Integra® Dermal Regeneration Template (DRT) at 5000-20,000 cells/cm in a porcine full-thickness burn model to test their regenerative capabilities. We evaluated healing outcomes, inflammation, neovascularization, collagen levels, and fibrosis markers. Wounds treated with CT-iMSCs showed notable improvements, including faster wound healing, better epithelialization, and marked improvements in healing markers compared to controls. These data support the potential of iMSCs as an ideal cell source for autologous skin regeneration.

摘要

严重烧伤存活的关键在于快速进行烧伤创面切除和闭合,但大面积伤口往往超出自然愈合能力。诸如合成皮肤替代品等替代疗法尚未成为标准的最佳解决方案。干细胞疗法,尤其是使用同种异体来源的疗法,在促进伤口修复方面显示出前景。诱导间充质干细胞(iMSCs)已展现出克服传统干细胞疗法局限性的巨大潜力。本研究在猪全层烧伤模型中,将脐带组织来源的iMSCs(CT-iMSCs)以5000 - 20000个细胞/平方厘米的浓度掺入成熟的表皮-真皮替代品Integra®真皮再生模板(DRT)中,以测试其再生能力。我们评估了愈合结果、炎症、新生血管形成、胶原蛋白水平和纤维化标志物。与对照组相比,用CT-iMSCs治疗的伤口显示出显著改善,包括伤口愈合更快、上皮化更好以及愈合标志物有明显改善。这些数据支持了iMSCs作为自体皮肤再生理想细胞来源的潜力。
