Figure 4From: An athymic rat model of cutaneous radiation injury designed to study human tissue-based wound therapyPhotographs obtained on the final day of the study for five rats, one rat for each dose level. Significant contraction is visible in all wounds created using doses of 52.6 Gy and higher. Contraction is seen to a lesser degree on one wound (left) created using the 41.5 Gy dose. Hair growth has resumed within areas irradiated using a 30.4 Gy dose.Back to article page
