Movat Pentachrom stain reveals unexpected high osteogenesis rate in aortic valves

Using this setup, a region of osseous metaplasia was detected in 25 (71.4%) of 35 samples analyzed. In some cases, these regions were small sized and only visible due to the bright color of Movat Pentachrom stain. This leads to the suggestion that a higher rate of calcified aortic valve samples would be classified as cusps with areas of neo-osteogenesis after staining with Movat Pentachrom stain and by the systematic analysis of larger parts of the tissue blocks.
