Two papers in this issue of Oncogene (Cheli et al., 2011; Strub et al., 2011) reveal that low-Mitf cells can initiate tumors with high efficiency, and that Mitf blocks senescence by regulating genes implicated in S-phase progression and mitosis....
Which phase of mitosis (prophase, metaphase, anaphase, or telophase) does a dividing cell spend most of its time in?Mitosis:Walther Flemming called the cell division pattern first observed in many cells across kingdoms as mitosis in 1882. Other alternative...
the nuclear genome in chromosomes is coupled with the Under the assumptions of both mutation-based and evolution of mitosis. Starvation and cannibalism are seen environmental models, asexual lineages should have as the main triggers for merging of cells and the evolution short live spans, either ...
Internodal cells of the main axis develop from a uninucleate segment cell (Pickett-Heaps, 1967). This nucleus and all further nuclei divide in the absence of a spindle, a process that is referred to as amitosis (equal division) or fragmentation (unequal division) (Bucher, 1959; Kisser, 192...
This Golgi arrangement is dynamic, under- going regulated disassembly/reassembly during mitosis, directed migration and polarized secretion [6]. The rib- bon also disassembles in response to membrane depo- larization, raised intracellular calcium, viral infection, autophagy induction and genotoxic ...
GSEA revealed a broad picture of increased cell prolif- eration and reduced differentiation associated with net- work hits in mice and low network metagene activity in human tumours (the concordant gene expression pattern), as demonstrated by significant enrichment of multiple genesets (see ...
Mitocheck: the goal of this resource is to integrate information on cellular functions of human genes while also giving access to supporting information such as microscopy images of phenotypes. Although its primary focus is on the biology of mitosis, the resource also integrates data relevant to ma...

To summarize, these studies identify the following six main stem cell types: ISCs, HSCs, GaSCs, GsSCs, LfcSCs and RNSCs. Although HSCs and GsSCs are capable of undergoing mitosis, they do not appear sufficiently potent to be activated under homeostatic conditions. However, stress-induced damag...
