Pulmonary fibrosis (PF) is a progressive and irreversible lung disease, characterized by poor prognosis with limited treatment options. Mesenchymal stem cells (MSCs) are multi-potent cells having the ability to self-renew and differentiate into multiple tissues, thus considered a novel treatment option. The present study aimed to investigate the possible antifibrotic effect of undifferentiated adipose tissue-derived mesenchymal stem cell (AD-MSC) therapy on PF experimentally induced in rats using amiodarone (AMD). AMD (30 mg/kg) was given orally, once daily for 12 consecutive weeks to induce lung fibrosis. Following the confirmation of lung damage with histopathological examination, AD-MSCs (2 × 106 and 4 × 106 undifferentiated MSCs) were injected once intravenously, followed by 2 months for treatment. AMD induced focal fibroblastic cells proliferation in the peribronchiolar tissue, as well as in between the collapsed emphysematous alveoli. Also, AMD significantly increased serum and lung homogenate fibroblast growth factor-7 (FGF7), Clara cell protein-16 (CC16), and cytokeratin -19 (CK19) levels, as well as the expression of both iNOS and NFкB in the lung alveoli. Moreover, AMD caused excessive collagen deposition and increased alpha smooth muscle actin (α-SMA) expression. All findings significantly regressed on stem cell therapy in both doses, with superior effect of the high dose, providing evidence that adipose tissue-derived MSCs could be a promising approach for the treatment of PF.

脂肪组织来源的间充质干细胞可预防胺碘酮引起的大鼠肺损伤。

肺纤维化(PF)是一种进行性且不可逆的肺部疾病,其预后较差,治疗选择有限。间充质干细胞(MSCs)是具有自我更新和分化为多种组织能力的多能干细胞,因此被认为是一种新颖的治疗选择。本研究旨在探讨未分化的脂肪组织间充质干细胞(AD-MSC)治疗对使用胺碘酮(AMD)实验性诱导的PF的可能的抗纤维化作用。口服AMD(30 mg / kg),每天一次,连续12周,以诱导肺纤维化。通过组织病理学检查确认肺损伤后,静脉注射AD-MSC(2×106和4×106未分化的MSC),然后进行2个月的治疗。AMD诱导支气管成纤维细胞在支气管周组织以及塌陷的肺气肿肺泡之间增殖。此外,AMD显着提高了血清和肺匀浆成纤维细胞生长因子7(FGF7),克拉拉细胞蛋白16(CC16)和细胞角蛋白-19(CK19)的水平,以及iNOS和NFкB在肺泡中的表达。此外,AMD导致过多的胶原蛋白沉积并增加了α平滑肌肌动蛋白(α-SMA)的表达。所有发现在两种剂量下均显着回归干细胞治疗,高剂量具有更好的效果,这提供了脂肪组织衍生的MSCs可能是有前途的PF治疗方法的证据。图形概要。AMD显着提高了血清和肺匀浆成纤维细胞生长因子7(FGF7),克拉拉细胞蛋白16(CC16)和细胞角蛋白-19(CK19)的水平,以及iNOS和NFкB在肺泡中的表达。此外,AMD导致过多的胶原蛋白沉积并增加了α平滑肌肌动蛋白(α-SMA)的表达。所有发现在两种剂量下均显着回归干细胞治疗,高剂量具有更好的效果,这提供了脂肪组织衍生的MSCs可能是有前途的PF治疗方法的证据。图形概要。AMD显着提高了血清和肺匀浆成纤维细胞生长因子7(FGF7),克拉拉细胞蛋白16(CC16)和细胞角蛋白-19(CK19)的水平,以及iNOS和NFкB在肺泡中的表达。此外,AMD导致过多的胶原蛋白沉积并增加了α平滑肌肌动蛋白(α-SMA)的表达。所有研究结果均表明,两种剂量的干细胞治疗均显着退步,高剂量的效果更佳,这证明来自脂肪组织的MSCs可能是治疗PF的有前途的方法。图形概要。AMD导致过多的胶原蛋白沉积并增加了α平滑肌肌动蛋白(α-SMA)的表达。所有发现在两种剂量下均显着回归干细胞治疗,高剂量具有更好的效果,这提供了脂肪组织衍生的MSCs可能是有前途的PF治疗方法的证据。图形概要。AMD导致过多的胶原蛋白沉积并增加了α平滑肌肌动蛋白(α-SMA)的表达。所有发现在两种剂量下均显着回归干细胞治疗,高剂量具有更好的效果,这提供了脂肪组织衍生的MSCs可能是有前途的PF治疗方法的证据。图形概要。
