Changes in ED1 positive cells in the choroid following systemic lipopolysaccharide injection

4 and 8 hoursIncreased number of round cells, occasionally accompanied by an increase of dendritiform cells
16 hoursA tremendous number of round cells, diffusely present in the whole area of the choroid with focal accumulation
24 hoursRound cells decreased in number, dendritiform cells numbers increased
48, 72, and 96 hoursA large number of dendritiform cells with more and longer dendrites and a larger but vague cell body was present, accompanied by a decrease of pleiomorphic cells
7, 10, and 14 daysBoth dendritiform cell and pleiomorphic cell numbers decreased and gradually returned to preinjection level
