Wilson's disease


Can anyone tell me if all copper stains require use of control tissue that is specifically diagnosed with Wilson's disease?  Historically, as was passed along to me....copper controls had to come from a liver with Wilson's disease.  One of our doctors recently told me any liver with chronic cholestasis (ie. Primary biliary cirrhrosis or Primary schlerosing cholangitis) is okay to use too.  I recently stained some fetal liver tissue and it looks great.  I am hoping the consensus from histoland confers that PBC and PSC liver tissue that stains great for copper is okay to use too.
