	A while back when teaching my immunology class about transplantation I told the
students about the attempts to produce human complement regulator transgenic
pigs to avoid alternate pathway mediated hyperacute rejection of their organs by
human recipients.  A very astute student asked why the pig valves which are
routinely used for valve replacement operations are not rejected by this
mechanism.  Anybody out there got any explanations?
