Small intestinal development in the young chick: Crypt formation and enterocyte proliferation and migration

Abstract: 1. Post-natch mucosal development was examined in the chick small intestinal epithelium using immunostaining with proliferating cell nuclear antigen (PCNA) and 5-bromo-2-deoxyuridine (BrdU). 2. On the day of hatching jejunal crypts were small and a single crypt per villus was observed. However, during the 108 h post-hatch crypts developed rapidly branching and increasing in size, cell numbers and cell size. 3. Almost all epithelial cells in the small intestine of the hatching chick were proliferating, as indic… Show more

“…Because early functioning of the gastrointestinal tract is vital for growth performance of chickens, it is crucial to optimise the development and functional capacity of the intestine (Uni and Ferket, 2004;Gurbuz et al, 2010). Crypt development is a crucial step in intestinal maturation (Uni et al, 2000), and the villus height/crypt depth ratio is a useful criterion for estimating the digestive cap acity in the small intestine (Montagne et al, 2003;Gurbuz et al, 2010). In our study, villus height/crypt depth ratio of the duodenum was higher in the YE group than the control, YCW and YCW+YE groups, and the villus width in the ileum was higher in the YCW, YE and YCW+YE groups than the control group, which would have affected intestinal absorption.…”

“…Segundo Uni et al (2000), o tamanho das criptas aumenta consideravelmente a partir da eclosão, atingindo um platô em aproximadamente 120 horas. A taxa de aumento do número de células por cripta também é maior nessa fase, atingindo valor máximo cerca de 108 horas pós-eclosão, declinando em seguida.…”

“…De acordo com a disponibilidade de nutrientes na gema o vilo aumenta de 200 a 300% do 17º dia de incubação até a eclosão (UNI et al, 2000;PEDROSO et al, 2005a).…”
