Staining occurs in the syncytiotrophoblasts, which predominate at this stage. Nuclei are lightly counterstained with haematoxylin  2005 2005 2007 2007 2000 2000 2004 2006 2007 2004 2005 2007 2007 1999 2000 1998 1995 2005 1997 1998 1998 1997 1998 2000 1999 2006 1999 2005 2003 2006 2006 1995 1998 2005 2007 2005 2007 2005 2005 2007 2007 Cancer cell fusions 2004 2000 2000 2006 2006 2007b 6 6 6 2007b P 2007b Fig. 6 a b c e d arrows  2007 2007 2007 2007 2007a b 2003 2002 1997 2002 1995 1999
