11.   Most studies entailing isolation of intestinal epithelial cells invitro and subsequent grafting invivo have used intact undifferentiated fetal endoderm.

12.   These compounds are absorbed into the epithelial cells surrounding the central lumen containing the colloid.

13.   Significant but heterogeneous increases werefound in urokinase type plasminogen activator concentrations of biopsy specimens originating from carcinomas of both epithelial cell types.

14.   The intensity of the immune response as measured by the ELISPOT correlates with the capability of the antigen of adhering to the epithelial cells.

15.   Recovery occurs when the affected intestinal epithelial cells on the villi are replaced by new enterocytes moving up from the crypts.
