Distribution of smooth muscle actin-containing cells in the human meniscus.
This is the first report of a contractile actin isoform, a-smooth muscle actin (SMA), in the cells of the human meniscus that lacked meniscal tears based on gross anatomical appearance. Approximately 25% of the cells in the tissue contained SMA by immunohistochemistry. Most of the SMA-positive cells were chondrocytic in morphology.
