In addition to histone modifications, histone variants and chromatin remodeling complexes also contribute to altering chromatin structure.
Three of the advances that have significantly pushed the envelope on cell line development include the identification, optimization, and utilization of technologies that control chromatin structure to maximize expression of recombinant genes, the development of next generation sequencing technologies that allow for sequencing of the whole CHO genome and sophisticated bioinformatics for improving analysis of sequencing data.
Highly significant differences were found for binucleated cells (Image 2), abnormalities of chromatin structures, chromatin bridges between the erythroblasts, incompletely divided polypoid cells and karyorrhexis in erythroblasts (Image 3).
The following analyses were carried out for each ejaculate: sperm motility assessment, sperm pH measurement, sperm morphology assessment, sperm chromatin structure evaluation and cell membrane integrity assessment.
Recent research suggests that ncRNA may have layers of information or signals that control chromatin structure and epigenetic memory.
We found that stem cells have a different chromatin structure than somatic (specialized) cells.
Fazzio has uncovered previously unknown processes governing how the chromatin structure of a cell's DNA influences gene expression in stem cells, conferring on these cells the unique ability to replicate and differentiate into many different types of cells.
The former include aniline/toluidine blue staining and protamine examination by chromomycine A3, while the latter mainly regard the TUNEL (Terminal deoxynucleotidyl tranferase mediated dUTP nick end labelling), COMET (single-cell gel electrophoresis), SCD (Sperm Chromatin Dispersion), SCSA (Sperm Chromatin Structure Assay), DNA ladder and DNA-break detection FISH (Fluorescence in situ hybridization) assays.

In recent years, it has been demonstrated that the dynamic association of histones and their variants to the genome plays a very important role in chromatin structure, while their post-translational modifications--acetylation, phosphorylation, methylation, ubiquitylation and ADP-ribosylation--participate in chromatin function and gene regulation (Berger, 2001).

Most genes are tightly packaged by a chromatin structure - chromatin being what compacts DNA so that it fits inside the nucleus of a cell.
