A new intracellular adenosine triphosphate (ATP) delivery technique has been developed and was tested for skin wound care.
Eleven pairs of adult nude mice were used. ATP-vesicles were applied in 11 mice, and another 11 mice were treated with lipid vesicles only.
The group treated with ATP-encapsulated fusogenic small, unilamellar lipid vesicles healed faster than the group treated with only lipid vesicles. Histologic study indicated better developed granular tissue and re-epithelialization in the study group, and wound tissue vascular endothelial growth factor expressions were also higher in ATP-vesicles treated mice.
This intracellular ATP delivery system may provide a new hope for wound healing as well as the treatment of medical conditions in which ischemia is involved.
已开发出一种新的细胞内三磷酸腺苷(ATP)递送技术,并对其进行了皮肤伤口护理测试。
使用11对成年裸鼠。11只小鼠应用ATP囊泡,另外11只小鼠仅用脂质囊泡处理。
用包裹ATP的融合性小单层脂质囊泡处理的组比仅用脂质囊泡处理的组愈合更快。组织学研究表明,研究组的肉芽组织发育更好,再上皮化更好,并且在ATP囊泡处理的小鼠中伤口组织血管内皮生长因子表达也更高。
这种细胞内ATP递送系统可能为伤口愈合以及涉及缺血的医学病症的治疗提供新的希望。
