WebTrichohyalin granules in the IRS consist of a framework of immunolabeled coarse filaments of 10-12 nm. The latter assume a parallel orientation and lose the immunoreactivity in fully cornified cells. Transglutaminase immunolabeling is diffuse among trichohyalin granules and among the parallel 10-12 nm filaments of maturing inner root cells. northgate high school pittsburgh pa
