RatChemical/toxinInbred strain not specifiedMaleSubcutaneous100 and 300 micrograms/kgAfter ulcer induction
Model: Gastric ulcer induced by submucosal injection of 0.03 ml of 20% acetic acid; delayed healing produced by daily indomethacin 1 mg/kg subcutaneously for 4 weeks
hEGF at 100 and 300 micrograms/kg significantly accelerated both natural and indomethacin-delayed healing of acetic acid gastric ulcers, and inhibited basal and histamine-stimulated acid secretion, suggesting healing is mediated largely by antisecretory activity.

RatSpinal cord injuryContusionSprague-DawleyFemalen = 5 per group for blots and BBB scoring, 4 per group for Evan…Subcutaneous near the wound for EGF; intrathecal for LY294002EGF 60 microg/kg; PI3K inhibitor LY294002 50 nmol/kg in 5 m…Started immediately after injury
Model: T9 laminectomy with moderate contusion spinal cord injury, 150 kdyn with no dwell time using an Infinite Horizon impactor
EGF preserved blood-spinal cord barrier integrity and improved locomotor recovery through PI3K/Akt/Rac1 dependent maintenance of junction proteins.

Model: High-dose whole-body irradiation (12 and 13 Gy, 60Co, 0.59-0.57 Gy/min) causing gastrointestinal damage
BMT and EGF each increased survival after 13 Gy and attenuated radiation-induced gastrointestinal atrophy while increasing regeneration in the first week, with the combination most effective; neither improved early cytopenia.

MouseIschaemia-reperfusionHepaticC57BL/6 wild type and VEGFR1 tyrosine kinase knockout (VEGFR1 TK-/-), including bone marrow chimerasMaleSystemic administration to VEGFR1 TK-/- mice (route not stated)During hepatic ischaemia and reperfusion
Model: Hepatic warm ischaemia and reperfusion by occlusion of the blood supply to the median and left hepatic lobes
VEGFR1 tyrosine kinase knockout mice showed delayed liver repair, sustained sinusoidal damage and reduced pro-angiogenic factor expression. Treatment with epidermal growth factor attenuated hepatocellular and sinusoidal injury in these mice.

MouseWoundBalb/cn = 60 mice randomised into 10 groups, 6 animals per grouptopical2,000 IU/mL, one spray per woundapplied after wounding; exact start time not stated
Model: Two 5 mm full thickness dorsal punch wounds through skin and panniculus carnosus per mouse
Topical EGF improved the healing rate from 72.73 to 90.54 per cent at day 14 with a more rapid and prolonged rise in Kindlin-1 expression; Kindlin-1 knockdown in vitro reduced activated integrin beta1 by approximately 36 to 58 per cent, migration by approximately 35 per cent and proliferation by ap…
