From: Evaluation of mouse enteroids as a model for Lawsonia intracellularis infection
Measurement of cellular proliferation in mouse enteroids. Enteroid sections were stained for Ki-67 antigen by immunofluorescence and percentages of Ki-67 positive cells were calculated for all treatment groups. Bars represent mean ± standard error of the mean. DMEM, enteroids microinjected with sterile DMEM; SN, enteroids microinjected with filter sterilized L. intracellularis culture supernatant; L. intacellularis, enteroids microinjected with L. intracellularis in suspension.
