Wound healing involves complex interplay between cellular and molecular events. In this study, we investigated the therapeutic potential of the bovine amniotic membrane (BAM) in wound healing using a mouse model. Twelve male C57BL/6 mice were divided into four groups: negative control (Vehicle), positive control (DuoDERM Extra Thin), amniotic membrane attachment (Amniotic Membrane), and compressed amniotic membrane attachment (Amniotic Membrane with Compression). The dorsal skin of each mouse was excised and wound-healing parameters were assessed over a two-week period. Our results revealed that the Amniotic Membrane and Amniotic Membrane with Compression groups demonstrated significant sustained reductions in the wound area compared to the Vehicle group. These reductions were more pronounced than those observed in the DuoDERM group. Histopathological analysis revealed advanced wound healing characteristics in the BAM-treated groups. Immunohistochemical analysis demonstrated elevated expression levels of wound healing markers (including α-smooth muscle actin, collagen type III, SMAD 1/5/8, and SMAD 2/3) in the BAM-treated groups compared to the control and DuoDERM groups. Conversely, cluster of differentiation 4 levels were significantly lower in BAM-treated groups. Overall, our findings highlight the therapeutic efficacy of BAM and compression in promoting wound healing. Thus, BAM offers a promising therapeutic approach for enhancing wound healing outcomes in clinical settings, potentially by modulating key wound healing pathways and processes.
伤口愈合涉及细胞和分子事件之间的复杂相互作用。在本研究中,我们使用小鼠模型研究了牛羊膜(BAM)在伤口愈合中的治疗潜力。将12只雄性C57BL/6小鼠分为四组:阴性对照组(赋形剂)、阳性对照组(多德美超薄型)、羊膜贴附组(羊膜)和压缩羊膜贴附组(压缩羊膜)。切除每只小鼠的背部皮肤,并在两周内评估伤口愈合参数。我们的结果显示,与赋形剂组相比,羊膜组和压缩羊膜组的伤口面积持续显著减小。这些减小比在多德美组中观察到的更为明显。组织病理学分析显示BAM治疗组具有先进的伤口愈合特征。免疫组织化学分析表明,与对照组和多德美组相比,BAM治疗组中伤口愈合标志物(包括α-平滑肌肌动蛋白、III型胶原、SMAD 1/5/8和SMAD 2/3)的表达水平升高。相反,BAM治疗组中的分化簇4水平显著较低。总体而言,我们的研究结果突出了BAM和压缩在促进伤口愈合方面的治疗效果。因此,BAM为改善临床环境中的伤口愈合结果提供了一种有前景的治疗方法,可能是通过调节关键的伤口愈合途径和过程来实现的。
