Presence of NCAM and its isoforms in normal and fibrotic kidneys.

<p>(<b>A</b>) RT-PCR: three NCAM isoforms in different renal samples, fibrosis was present in 3 cases, lanes IV, VIII and X. (<b>B</b>) RT-PCR: presence of all NCAM isoforms in FSGS. (<b>C</b>) RT-PCR: presence of all NCAM isoforms in MPGN. (<b>D</b>) Same case as Fig (B): increased NCAM expression in areas with slight fibrosis on cryostat section, immunoperoxidase, clone Eric-1, x200. (<b>E</b>) Same tissue as Fig (C): NCAM positivity in peritubular incipient interstitial fibrosis shown on cryostat section, immunoperoxidase, clone Eric-1, x400.
