Abstract: The invention concerns a filter insert (1) that is provided as an exchangeable insert in a filter, in particular an oil filter, fuel filter or the like of an internal combustion engine. The filter comprises a filter housing (3) that can be separated along a separating plane (2) and the exchangeable filter insert (1) extending in an axial direction (18). Two housing parts (4, 5) of the filter housing (3) are sealed relative to one another along the separating plane (2) by means of a seal (6). The seal (6) is secured slidably and captively in the axial direction (18) on the filter insert (1).

Abstract: Dendritic cells are of interest therapeutically as antigen-presenting cells. A process is disclosed in which peripheral blood cells are first isolated and the CD 34 antigen-expressing blood progenitor cells which they contain are then enriched. These enriched cells are expanded ex-vivo using a combination of haematopoietic growth factors and cytokines. Over a period of 10-20 days, they give rise, in particular to dendritic cells which, where appropriate, can be purified still further. These cells are functionally active with regard to the ability to present antigen.
