概括

从带衍生中介质 stromal 细胞 (UC-MSC-sEVs) 中的小细胞外囊促进纤维细胞的增殖,并减少黑色素的产生. 然而,UC-MSC-sEVs在局部应用中不能有效地穿透皮肤屏障.

科学领域:

生物医学工程生物医学工程
皮肤病学皮肤病学
再生医学是一种再生医学.

背景情况:

在皮肤应用中,中酶体 stromal 细胞衍生的细胞外囊泡 (MSC-sEVs) 是有前途的.
有限的研究存在于带衍生MSC-sEVs (UC-MSC-sEVs) 用于痕减少和超色素化.
了解UC-MSC-sEVs对皮肤细胞外基质 (ECM) 和色素的影响至关重要.

研究的目的:

评估UC-MSC-sEVs对皮肤ECM合成的影响.
评估UC-MSC-sEVs对色素的影响.
研究UC-MSC-sEVs在痕减少和皮肤亮化方面的潜力.

主要方法:

使用人类皮肤纤维细胞 (HDF) 和黑色素瘤细胞 (MNT-1) 的体外研究.
评估了HDF的扩散,迁移,抗氧化活性和ECM基因表达.
检查了MNT-1的扩散,黑色素含量和铁酶活性.
使用ex vivo皮肤模型来评估UC-MSC-sEVs的皮肤透率.

主要成果:

UC-MSC-sEV增加了HDF的增殖和上调的纤维素,MMP-1和MMP-3基因表达.
没有观察到HDF迁移,原蛋白类型1/3或SOD表达的显著变化.
UC-MSC-sEVs降低了MNT-1细胞中的黑色素合成,而不影响铁酶活性.
局部应用显示UC-MSC-sEV在18小时后仍然存在角层中,这表明皮肤透率较低.

结论:

UC-MSC-sEVs显示出刺激纤维细胞增殖和调节ECM合成的潜力.
UC-MSC-sEVs可以降低黑色素的产生,这表明在皮肤亮化中的应用.
皮肤透率较低限制了UC-MSC-sEVs在痕减少和色素处理方面的局部疗效.

Clinical Applications of Epidermal Stem Cells

Clinical Applications of Epidermal Stem Cells

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...

Mesenchymal Stem Cells

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...
