This study was conducted to investigate the effects of the combination of Glucagon-like peptide-2(GLP-2)and dipeptidyl peptidase-Ⅳ(DPP-Ⅳ)inhibitors with different concentrations on cell proliferation,metabolism and enzyme activity of primarily intestinal epithelial cells cultured in vitro from 28-day-old weaned piglets,and aimed to explore the method of promoting GLP-2effects.The experiment,taking 28-day-old weaned piglets' intestinal epithelial cells as a model,studied the effects of DPP-Ⅳinhibitors(KR6243...
