Specific antibody plaque-forming cells (PFC) to Shigella-soluble antigen did not appear in spleen cell cultures from Shigella-tolerant mice, as occurred with similar cultures prepared from normal mice immunized with Shigella antigen prior to sacrifice. Cultures from tolerant mice also failed to form serologically detectable amounts of agglutinins in vitro. Exposure of cell cultures from toleran...

purpose: to evaluate the effect of human amniotic fluid (haf) on the growth of human corneal endothelial cells (hcecs) and to establish an in vitro method for the expansion of hcecs. methods: hcecs were cultured in dmem-f12 supplemented with 20% fetal bovine serum (fbs). confluent monolayer cultures were trypsinized and passaged using 20% fbs- or 10%, 20%, or 30% haf-containing media. cell prol...
