PURPOSE

This is an in-vitro experimental study to analyze the effect of Exo-HUVEC on endothelial cell (CD31), cell proliferation, matrix metalloproteinase 1 (MMP-1) and collagen type 1 on irradiated fibroblast with UVB as photo-aging model.

PATIENTS AND METHODS

Fibroblast cultures were divided into 5 groups, namely without UVB exposure, UVB exposure 600mJ/cm for 80 seconds as photo-aging model, and UVB exposure +Exo-HUVEC exposure 0.1%, 0.5% and 1%. The endothelial cell was stained with a CD31 marker, MMP-1 were examined with ELISA, cell proliferation is detected using an MTT assay; meanwhile, collagen type 1 deposition and endothelial cell were measured using flowcytometry.

RESULTS

This study found positive endothelial cell marker CD31. Significant difference was found in cell proliferation, MMP-1 and collagen type 1 level between the control group with UVB irradiation and the treatment group with Exo-HUVEC (p < 0.05).

CONCLUSION

Exo-HUVEC significantly increases cell proliferation and collagen type 1 level, while decrease MMP-1 levels on irradiated fibroblast; therefore, Exo-HUVEC ameliorate the photo-aging of skin fibroblast.

目的

本研究为体外实验研究，以UVB照射成纤维细胞建立光老化模型，分析人脐静脉内皮细胞来源外泌体（Exo-HUVEC）对内皮细胞（CD31）、细胞增殖、基质金属蛋白酶1（MMP-1）和I型胶原蛋白的影响。

患者和方法

将成纤维细胞培养物分为5组，即未暴露于UVB组、以600mJ/cm²照射80秒作为光老化模型的UVB暴露组，以及UVB暴露+0.1%、0.5%和1%的Exo-HUVEC暴露组。用CD31标记物对内皮细胞进行染色，用ELISA检测MMP-1，用MTT法检测细胞增殖；同时，用流式细胞术检测I型胶原蛋白沉积和内皮细胞。
