Anti-smooth muscle antibodies (SMA) detected by indirect immunofluorescence. A, B, and C Rodent kidney substrate; A vascular pattern (V); B vascular and glomerular pattern (VG); C vascular, glomerular, and tubular pattern (VGT). D Rodent stomach: staining of smooth muscle fibres between the gastric glands. E Human fibroblasts showing the so called “actin pattern” of SMA. F Vascular smooth muscle (VSM) 47 cells, also showing the “actin pattern.” G Rodent kidney showing the simultaneous presence of SMA with VG pattern and homogeneous ANA in a patient with autoimmune hepatitis type 1
