[Long-term tissue culture of normal and atherosclerotic human arterial explants (author's transl)].

A method for longterm tissue culture of human arterial explants is described. The explants of normal and atherosclerotic femoral arteries, removed immediately post mortem, were kept in culture for up to 14 days in a biochemically active state.
