| dc.description.abstract | SUMMARY
The aim of the present study was to analyse the immunoreactivity of α-smooth
muscle actin (α-SMA), smooth muscle marker on bovine intact tissues.
The following tissues showed diffuse, homogenous, intense, cytoplasmic, α-SMApositivity:
skin: arrector pili muscle, tunica media cells of the dermal vessels,
myoepthelial cells around the apocrin glands, and ducts; lymph node (Figs 1. and 2.),
haemolymph node, spleen (Figs 3. and 4.): capsule, trabecules, extra- and
intraparenchymal vessels; tongue: vessels, myoepithelial cells of the intermuscular
glands; oesophagus: lamina muscularis mucosae, vessels, myoepithelial cells of the
glands, tunica muscularis (Figs 5. and 6.); proventricules, abomasum: lamina muscularis
mucosae, vessels, tunica muscularis (Fig 7.); small intestine, large intestine:
lamina muscularis mucosae, pericryptal myofibroblasts, vessels, tunica muscularis
(Figs 8. and 9.); liver: perisinusoidal myofibroblasts, portal (periductal) myofibroblasts,
tunica media cells of the intrahepatic vessels (Figs 10.); kidney: smooth
muscle cells of the intrareanal arteries and veins, subepithelial smooth muscle
cells around the pelvis renalis, myofibroblasts of the capsule (Figs 11. and 12.);
urinary bladder: lamina muscularis mucosae, vessels, tunica muscularis (Figs 13.
and 14.); uterus: myometrium, smooth muscle cells of the vessels (Figs 15. and 16.);
ovary gland: myofibroblast cells of the theca externa layer, vessels; lung: tunica
media cells of the intrapulmonary vessels, smooth muscle cells in the wall of
the micro-, macrobronchus; myocardium: tunica media cells of the coronary
vessels; aorta: intramural smooth muscle cells, -small vessels. The authors
propose the immunohistochemicaly validated, α-SMA-positive bovine tissues for
reliable external or internal positive controls in a variety of immunohistochemical
pathology studies. | en_US |
