AI Technical Summary
Existing technologies struggle to produce human epidermal growth factor (hEGF) efficiently and stably, and its instability in liquid formulations makes sustained release and targeted delivery difficult, limiting its application in wound healing and cosmetics.
By introducing hydrophilic glycine into the C-terminus of hEGF and fusing it with a His tag, an E. coli expression system was used, followed by nickel column affinity chromatography purification, and then combined with a ROS-responsive hydrogel composition to achieve efficient expression and stable delivery.
This study achieved efficient expression and stable purification of hEGF, reduced production costs, and provided application potential in wound healing and skin repair. Furthermore, the hydrogel composition enabled stable drug release and efficient absorption in the wound environment.
