| Research Abstract |
In this study, we attempted to visualize in vivo therapeutic response of infliximab (IFX) in the murine UC model using two photon laser scanning microscopy (TPLSM) and to analyze their histopathological response morphologically. Both extensive inflammatory cell infiltration and the damage or loss of epithelial cells in the crypt was observed in vivo real-time in the dextran sodium sulfate (DSS) colitis model of green fluorescent protein (GFP) expressing mice using TPLSM. The number of leukocyte infiltrates within the crypt (2.4 versus 6 per field of view: FOV) and the number of crypt loss (1.0 versus 4.5 per FOV) were reduced in IFX-treated mice, compared with non-IFX, control mice. The length of colonic crypt (99.8 versus 80.0 micrometer) was increased in IFX-treated mice, compared with non-IFX, control mice. Serial change in regenerative epithelial cells was not observed, which regenerated from the bottom of the crypt toward the top of the crypt (the luminal side).
