Robust (> 80%) site-specific and Dnmt2-dependent cytosine-5 methylation was observed at C38 of tRNA GlyGCC, AspGUC, and ValAAC in bone marrow cells as well as in MSCs and their differentiated derivatives (Fig 4A).
In conclusion, the in vivo vascularized tissue engineering chamber supports the survival through implantation of human iPS cells and their differentiated progeny, as well as a novel platform for rapid teratoma assay screening for pluripotency.
Array data of the induced pluripotent stem cells (iPS cells) and ESCs, as well as their hepatic differentiated progenies, were from GEO dataset GSE14897 [ 19].
Given that another major Rho GTPase, Cdc42, also distinctively functions in ES cells as compared to their differentiated progenies [53], pluripotent stem cells in general may have unique signaling mechanisms regulated by Rho GTPases.
The data presented here, indicate that SBDS expression levels decrease during human neutrophil differentiation, indicating that SBDS plays its most prominent role in myeloid progenitors as compared to their differentiated progeny.
In addition, undifferentiated mESCs appear to have a higher level of global histone acetylation with transcriptional hyperactivity as compared to their differentiated derivatives.
The chromatid exchange aberration rates in hESCs increased manifold 2 hours after irradiation as compared with their differentiated derivatives, but the frequency of radiation-induced chromatid breaks was similar.
We are now evaluating the expression of MHC I and of some NK ligands in TUBO-derived CSCs to assess whether NK cells recognize and more efficiently kill CSCs than their differentiated counterparts, as has already been shown for colon cancer-derived CSCs [ 142].
ES cells are cultured as an attached monolayer, but their differentiated derivatives grow as unattached spheres.
