Dec 24, 2013 · Chromatin modifiers and remodellers: regulators of cellular differentiation Taiping Chen 1–3 and Sharon Y R Dent 1–3 Abstract Cellular differentiation is, by definition, epigenetic Genome-wide profiling of pluripotent cells and differentiated cells suggests global chromatin remodelling during
Chapter 1 An Overview of the Molecular Basis of Epigenetics
molecular basis for this type of change in DNA or chromatin structure in the nervous sys-tem is the focus of this chapter 7–9 By this definition, the regulation of chromatin structure and attendant DNA chemical modification is equivalent to epigenetic regulation
Chromatin diminution in Mesocyclops edax (Crustacea, Copepoda
Chromatin diminution is defined as the elimination of DNA during the differentiation of early embryonic cells into pre-somatic cells While it was first observed in the nematode Parascaris equorum, it also been identified in other parasitic nematodes, hagfish and copepods In the copepod Mesocyclops edax,
Cell Identification
mature appearing moderately granular chromatin, lack distinguishable nucleoli and have round to irregular nuclei (Figure 6) However, even in these cases, occasional lymphoblasts with more typical morphology such as larger size, finer chromatin and distinct nucleoli will be seen Thus, it is helpful to scan the slide on low power to evaluate
