An example of adenoviral gene therapy in the human diabetic organ-cultured corneas is presented towards the normalization of delayed wound healing and markedly reduced epithelial stem cell marker expression in these corneas. It also describes the optimization of this process in stem cell-enriched limbal epithelial cultures.

Neural crest (NC) cells derived from human pluripotent stem cells (hPSC) have great potential for modeling human development and disease and for cell replacement therapies. Here, a feeder-free adaptation of the currently widely used in vitro differentiation protocol for the derivation of NC cells from hPSCs is presented.

This protocol details the derivation of transplantable hematopoietic stem cells from mouse embryonic stem cells (ESC) and their subsequent injection into lethally irradiated recipient mice. Briefly, ESC are differentiated as embryoid bodies, which are then infected with retroviral HoxB4 and co-cultured with OP9 stromal cells and hematopoietic cytokines.
FAQs
Nanog contributes to pluripotency by operating within a regulatory network rather than acting as an isolated indicator. Its interactions with Oct4 and Sox2 help sustain gene-expression programs linked to the undifferentiated state, while the same network is associated with limiting differentiation. This systems-level role explains why Nanog measurements can reflect coordinated changes in cell state.
A Nanog signal should not be treated as standalone proof of pluripotency. The overview says interpret it with additional markers and functional evidence. In practice, researchers can combine Nanog measurements with other indicators of cell identity and with evidence that cells retain the relevant capacity, producing a stronger characterization than expression data alone.
Nanog expression can be tracked as cells undergo differentiation because the marker is measured to assess changes in cellular state. A measured change is meaningful only within the experimental context and alongside additional markers or functional evidence. This approach helps distinguish a shift away from an undifferentiated profile from an isolated measurement variation.
qPCR, immunostaining, and immunoblotting provide complementary ways to examine Nanog. qPCR measures Nanog RNA, whereas immunostaining and immunoblotting are used to assess Nanog protein. Using RNA and protein measurements can broaden characterization of cell identity and state, while comparisons during differentiation can reveal associated changes.
A basic Nanog analysis starts by deciding whether the study will assess RNA, protein, or both. Researchers then apply qPCR for RNA or immunostaining and immunoblotting for protein, and interpret the result in relation to cell identity, state, or differentiation. Pairing these measurements with additional markers and functional evidence strengthens conclusions.
Nanog analysis supports several areas of biology, including embryonic development, cellular reprogramming, organoid formation, and regenerative biology. In these settings, measurements can help characterize cell identity and state or track changes associated with differentiation. The findings are most informative when expression data are integrated with additional markers and functional evidence.
