Fig. 2From: Morphological adaptation of sheep’s rumen epithelium to high-grain diet entails alteration in the expression of genes involved in cell cycle regulation, cell proliferation and apoptosisExpression of genes related to cell cycle regulation in the ruminal epithelium of hay-fed (CON) and high-grain-fed sheep (G7–28). Values are mean ± SEM, n = 5. a, b Values within a column differ if they do not share a common superscript (P < 0.05). Sheep assigned to CON (n = 5), G7 (n = 5), G14 (n = 5) and G28 (n = 5) received a high-grain diet for 0, 7, 14 and 28 d, respectively.
