A peritubular myoid (PTM) cell is one of the smooth muscle cells which surround the seminiferous tubules in the testis. These cells are present in all mammals but their organization and abundance varies between species. The exact role of PTM cells is still somewhat uncertain and further work into this is needed. … See more PTM cells are endothelial cells which are understood to have derived from mesonephric cells. The structure and organization between PTM cells have been observed to be distinctly different between … See more Contractile Peritubular myoid cells are responsible for the contractile nature of the seminiferous tubule. This contraction helps move the spermatozoa and … See more PTMs were first observed in 1901, when Claudius Regaud made a detailed study of the histology and physiology of the seminiferous tubules in rats.
