Observations on the three-dimensional structure of the nucleolar channel system of the human endometrial glandular cell.
Nucleolar channel systems from human endometrial glandular cells have been subjected to three-dimensional analysis using a goniometer stage. The results are compatible with a secondary helical conformation of the constituent tubules and this idea has been incorporated into an improved model of the channel system.
