Nuclear pores
The nuclear envelope contains openings called nuclear pores, which consist of a complex of proteins encircling an opening. Nuclear pores regulate the bi-directional transit of materials between the cytoplasm and nucleus. In this image, six pores are visible and are marked by sites where the perinuclear space is obscured and the heterochromatin is interrupted. 38,000x
