Enzymatic digestion with pronase and DNAase was used to isolate Kupffer cells from mouse liver. The characteristics of these cells were found to be similar to those of peritoneal macrophages, except that in the initial suspension the percentage of Kupffer cells with Fc receptors was low, C receptors were absent and the ingestion of opsenized bacteria was(More)
Several methods for the preparation of cell suspensions from human gastrointestinal mucosa were investigated. Satisfactory suspensions were obtained by incubating tissue fragments in a solution of collagenase and hyaluronidase overnight at 4 degrees C followed by 30 minutes at 37 degrees C. The resulting suspension contained large numbers of intact lymphoid(More)
