皮肤损伤修复过程中伤口处的luc表达情况。A：损伤修复过程中不同时间点的成像结果（n=3）。0天为损伤后立即成像，之后分别在损伤后的第1、4、7、10、14、17和21天进行成像；B：应用活体成像软件量化伤口处的荧光值（p/s）。伤口处luc荧光值先逐渐增强后逐渐减弱(P < 0.001)

Luc expression during wound-healing. A: The wound-healing model mice were imaged at selected time points (n =3). The day 0 image was taken immediately after wounding, and subsequent images were taken on days 1, 4, 7, 10, 14, 17, and 21 after wounding. B: Quantification of luciferase expression (p/s) from the wound area with Living Image software. Luc expression first increased, and then decreased in the wound area (P < 0.001)
