Cohesin depleted cells pass through mitosis and reconstitute a functional nuclear architecture.

The human genome forms thousands of “contact domains”, which are intervals of enhanced contact frequency. Some, called “loop domains” are thought to form by cohesin-mediated loop extrusion. Others, called “compartmental domains”, form due to the …

Nucleome Imaging Toolbox is an R package for quantitative analyses of the 3D nuclear landscape recorded with super-resolved fluorescence microscopy.

Quantitative analysis of the nuclear landscape

Workflow for quantitative analysis of the nuclear landscape.

Initial high-resolution microscopic mapping of active and inactive regulatory sequences proves non-random 3D arrangements in chromatin domain clusters

Background: The association of active transcription regulatory elements (TREs) with DNAse I hypersensitivity (DHS[+]) and an open local chromatin configuration has long been known. However, the 3D topography of TREs within the nuclear landscape of …

Quantitative analyses of the 3D nuclear landscape recorded with super-resolved fluorescence microscopy

Recent advancements of super-resolved fluorescence microscopy have revolutionized microscopic studies of cells, including the exceedingly complex structural organization of cell nuclei in space and time. In this paper we describe and discuss tools …

Stage-dependent remodeling of the nuclear envelope and lamina during rabbit early embryonic development

Utilizing 3D structured illumination microscopy, we investigated the quality and quantity of nuclear invaginations and the distribution of nuclear pores during rabbit early embryonic development and identified the exact time point of nucleoporin 153 …

Remodeling of the Nuclear Envelope and Lamina during Bovine Preimplantation Development and Its Functional Implications

The present study demonstrates a major remodeling of the nuclear envelope and its underlying lamina during bovine preimplantation development. Up to the onset of major embryonic genome activation (MGA) at the 8-cell stage nuclei showed a non-uniform …

Reprogramming of fibroblast nuclei in cloned bovine embryos involves major structural remodeling with both striking similarities and differences to nuclear phenotypes of in vitro fertilized embryos

Three-dimensional super-resolution microscopy of the inactive X chromosome territory reveals a collapse of its active nuclear compartment harboring distinct Xist RNA foci.

BACKGROUND: A Xist RNA decorated Barr body is the structural hallmark of the compacted inactive X territory in female mammals. Using super-resolution three-dimensional structured illumination microscopy (3D-SIM) and quantitative image analysis, we …
