It is noteworthy to mention that these mouse mast cell phenotypes can vary significantly according to mast cell location, animal strain, and whether or not the tissue is inflamed [ 50– 50].
Here, we show that somatic deletion of Nrbp1 in the mouse causes a progenitor cell phenotype that disrupts the normal programme of cellular differentiation and proliferation along the intestinal crypt villus axis.
These functions for ICAM-2 were independent of immune stimulation, since the tumorigenic potential of ICAM-2-expressing neuroblastoma cells as xenografts in SCID mice was unaffected and cell phenotype was altered in vitro as well as in vivo.
In a serendipitous observation, Cadwell et al. (2010) found that moving the Atg16L1-deficient mice from conventional barrier living conditions to an enhanced barrier facility (i.e., a "super pathogen-free" environment) surprisingly protected the mice from the Paneth cell phenotype of aberrant granule packaging.
This is exemplified in infected Foxo3 deficient mice (a strain derived independently of the Foxo3 miceeR1 mice) where the resulting T cell phenotype is due to enhanced inflammatory cytokine production by myeloid cells (Dejean et al., 2009).
Analysis of the mutant phenotype in a mouse cell line revealed that loss of the enzyme leads to reduced cellular proliferation and a senescence-like phenotype.
We showed that: (i) Accumulating hyperplastic pAkt+ cells in prostates of PSA-Cre Pten-loxP/loxP mice have a luminal ePSA-Cre Pten-loxP/loxPPSA-Cre Pten-loxP/loxPknown and novel identified miceers of epithavealuminalnitor cepithelial
In mice the more mature NK cell phenotype is found in the lung epithelium, which is CD27lo CD11bhi, very similar in function to the human subset.
It is notable that among the top 5 highly-expressed SAE-enriched transcription factors were ELF3, which promotes epithelial morphogenesis [ 92], and embryonic stem cell-related gene SOX2, recently shown to be important for the progenitor cell function of the airway basal cells and Clara cells and induction of the airway epithelial cell phenotype in mice [ 36- 38].
As expected, most of the overlap between the differentially expressed gene set in PR-SET7 ΔHepA livers and normal ductal progenitors was detected in gene categories A and E. Collectively our results suggest that hepatocellular carcinoma in PR-SET7 ΔHepA mice has a cancer stem cell phenotype combining fetal hepatoblast-like and ductal progenitor cell-like features.
