  • Title: Effect of age on epithelial cell migration in small intestine of chickens.
    Author: Moon HW, Skartvedt SM.
    Journal: Am J Vet Res; 1975 Feb; 36(2):213-5. PubMed ID: 1111387.
    Abstract:
    Villous length, crypt depth, epithelial cell migration rate, and replacement time were studied by autoradiography of histologic sections of small intestine from normal chickens exposed to tritiated thymidine (3-H-TdR). The results indicated that villi and crypts elongate, and epithelial cell migration accelerates between 1 day and 6 months of age. Epithelial replacement time seemed to increase with age of the chickens. Replacement was nearly complete in the 1-day-old group of chickens 5 days after thymidine exposure. In contrast, at this same time, replacement was only approximately 75 and 50% complete in the 3-week-old and 6-month-old groups of chickens, respectively.
