Taken together, our FISH and AFM data thus indicated that DMs underwent repeated topographical fluctuations during the cell cycle, moving rapidly from locations in the nuclear interior at interphase to positions adjacent to the telomeres at prometaphase, where they remained through telophase to finally drift back into the interior of the newly formed interphase nucleus.
This is achieved with epidermal progenitor cells (EPCs) in the basal cell layer of the epidermis, which undergo an unlimited number of symmetric and asymmetric cell divisions, giving rise to daughter cells that either proliferate or exit the cell cycle and move to the suprabasal layer of the epidermis.
The granular neurons forming the internal granular layer descend from the EGL after exiting the cell cycle and move radially from the outer cerebellar surface beneath the PC layer along the guiding Bergmann glia, thereby making their connections with the PC dendrites.
DOI: http://dx.doi.org/10.7554/eLife.03563.018 During the S-phase of the cell cycle, telomerase moves from Cajal bodies to telomeres to counteract the progressive shortening of the telomere that occurs during DNA replication (Jady et al., 2006; Tomlinson et al., 2006; Cristofari et al., 2007; Stern et al., 2012).
It is worth noting here that the levels of p57Kip2 are very low in proliferating cells and differentiation signals result in its accumulation, which is necessary to withdraw cells from the cell cycle and to move them toward differentiation [7].

On terminal differentiation, basal keratinocytes exit from the cell cycle and subsequently move into the suprabasal layers.
In the adult worm, meiocytes progress through the meiotic cell cycle as they move along the gonad tube from the distal tip to the spermatheca.
The Proliferation component of these cells continuously moves over the cell cycle stages and concurrently, the motion unit moves the agent vertically over the four bottom fiber indexes in the grid.
Known as interkinetic nuclear migration (INM), these movements are synchronized with the cell cycle such that nuclei move basally during G1-phase and apically during G2-phase.
