目的

探讨负载人脂肪间充质干细胞(ADSCs)外泌体(Exos)的人脱细胞羊膜(HAAM)对小鼠全层皮肤缺损创面愈合的影响及其潜在作用机制。

方法

从抽脂手术获取的脂肪组织中分离ADSCs,从ADSCs中提取Exos并鉴定;从来源于胎盘的羊膜组织中分离羊膜制备HAAM并表征。取33只BABL/c小鼠,于背部制备全层皮肤缺损模型。其中9只小鼠皮肤缺损处予以HAAM补片缝合,分别于术后第3、7、14天通过组织切片Ⅳ型胶原荧光染色评估HAAM的生物降解情况。将其余24只小鼠分为对照组、HAAM组、Exos组和Exos/HAAM组,每组6只。对照组创面不作处理,HAAM组创面覆盖HAAM补片,Exos组创面使用100 μg ADSCs-Exos,Exos/HAAM组创面覆盖含100 μg ADSCs-Exos的HAAM补片。分别于术后第7、14天,通过形态学观察和组织学苏木精-伊红(HE)染色及Masson染色评估创面愈合程度;于术后第14天使用细胞因子抗体微阵列检测小鼠创面组织趋化因子表达的变化。

结果

成功分离并鉴定ADSCs-Exos。扫描电子显微镜下HAAM支架呈疏松多孔结构。荧光染色结果显示,术后第14天HAAM已大部分降解。小鼠皮肤创面模型实验显示,术后第7天Exos/HAAM组创面愈合率显著高于其他组;HE染色结果显示,术后第7天Exos/HAAM组上皮化优于其他组;Masson染色结果显示,术后第14天Exos/HAAM组胶原含量高于其他组;细胞因子抗体微阵列检测结果显示,术后第14天Exos/HAAM组叠加了HAAM组和Exos组趋化因子的表达。

结论

Exos/HAAM复合物支架可增加小鼠创面组织趋化因子的表达,促进皮肤创面愈合。

Objective

To investigate the effects and the potential mechanism of a composite scaffold constructed by human acellular amniotic membrane (HAAM) loaded with exosomes from adipose-derived mesenchymal stem cells (ADSCs-Exos) on full-thickness skin defect wound healing in mice.

Methods

ADSCs were isolated from adipose tissue obtained by liposuction, and ADSCs-Exos were collected and characterized. HAAM was prepared from placental amniotic tissue and characterized. Thirty-three BALB/c mice were selected to establish dorsal full-thickness skin defect models. In 9 mice, HAAM patches were sutured to the skin defects. The biodegradation of HAAM was evaluated by type Ⅳ collagen immunofluorescence staining of tissue sections on postoperative days 3, 7, and 14. The remaining 24 mice were divided into control group, HAAM group, Exos group, and Exos/HAAM group, with 6 mice per group. The control group received no treatment; the HAAM group was covered with HAAM patch; the Exos group was treated with 100 μg ADSCs-Exos; and the Exos/HAAM group was covered with HAAM patch containing 100 μg ADSCs-Exos. Wound healing was evaluated by morphological observation, hematoxylin-eosin (HE) staining, and Masson staining on days 7 and 14 post-surgery. Cytokine antibody microarray was performed on day 14 to detect the expression changes of chemokines at the wound site.

Results

ADSCs-Exos were successfully isolated and identified. Scanning electron microscopy revealed a loose and porous structure of the HAAM scaffold. Immunofluorescence staining revealed that the HAAM had largely degraded by day 14 post-surgery. In the mice wound model, the Exos/HAAM group exhibited significantly higher wound healing rate on day 7 post-surgery compared to other groups. HE staining showed that the epithelialization in the Exos/HAAM group was better than that in other groups on day 7 post-surgery. Masson staining demonstrated that collagen content in the Exos/HAAM group was higher than that in other groups on day 14 post-surgery. Cytokine antibody microarray analysis indicated that the Exos/HAAM group exhibited superimposed expression of chemokines from both HAAM group and Exos group on day 14 post-surgery.

Conclusion

The Exos/HAAM composite scaffold promotes chemokine expression in wound tissue and accelerates wound healing in mice.
