From: In vitro decidualisation of canine uterine stromal cells
Immunostaining against smooth muscle alpha actin (αSMA). a Decidualised canine stromal cells expressing αSMA (green); blue nuclear staining was achieved by DAPI. b Immunohistochemical localization of αSMA in canine pre-implantation uterus (solid arrows = blood vessels; open arrows = smooth muscle cells of myometrium, open arrowheads = uterine stromal cells, solid arrowheads = uterine glands). c, d Immunohistochemical localization of αSMA in canine mid-term placenta (solid arrows = large maternal vessels; open arrows = decidual cells)
