Induced Pluripotency

Induced pluripotent stem cells (iPSCs) are somatic cells that have been genetically reprogrammed to form undifferentiated stem cells. Like embryonic stem cells, iPSCs can be grown in culture conditions that promote differentiation into different cell types. Thus, iPSCs may provide a potentially unlimited source of any human cell type, which is a major breakthrough in the field of regenerative medicine. However, more research into the derivation and differentiation of iPSCs is still needed to...

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore called induced pluripotent stem...

Combinatorial Gene Control

2020
Combinatorial gene control is the synergistic action of several transcriptional factors to regulate the expression of a single gene. The absence of one or more of these factors may lead to a significant difference in the level of gene expression or repression. The expression of more than 30,000 genes is controlled by approximately 2000-3000 transcription factors. This is possible because a single transcription factor can recognize more than one regulatory sequence. The specificity in gene...

Despite recent advancements in genetic modification, transfection of human embryonic stem cells (HESCs) remains a capricious process. To our knowledge, systematic and efficient methods to transfect human induced pluripotent stem cells (iPSCs) have not been reported. Here, we describe robust protocols to efficiently transfect and nucleofect human iPSCs.

Generating induced pluripotent stem cell (iPSC) lines produces lines of differing developmental potential even when they pass standard tests for pluripotency. Here we describe a protocol to produce mice derived entirely from iPSCs, which defines the iPSC lines as possessing full pluripotency1.
FAQs
Their protein products, particularly transcription factors such as OCT4, SOX2, and NANOG, bind regulatory DNA and coordinate interconnected gene-expression networks. These networks support self-renewal while repressing programs associated with differentiation. This balance keeps a cell in a flexible state rather than committing it prematurely to one specialized lineage, making the genes central to cell-fate regulation.
OCT4, SOX2, and NANOG function as transcription factors that act at regulatory DNA rather than as isolated markers. Their combined activity helps coordinate the expression of genes that preserve stem-cell identity and suppress differentiation programs. Studying their activity therefore reveals how several regulatory components work together to maintain a pluripotent state.
Epigenetic regulation helps explain how cells control gene activity during changes in identity without changing the underlying genetic information. In the context of pluripotency genes, this regulation is relevant to preserving stem-cell characteristics and controlling differentiation programs. Examining these relationships can clarify how cells make and maintain developmental decisions during early development and reprogramming research.
Researchers use the activity of pluripotency genes as part of the process for generating induced pluripotent stem cells. Their regulatory effects help establish or assess a stem-cell-like state, including the capacity for self-renewal and later differentiation. This application connects gene-regulation studies with experimental systems for investigating development, disease, therapies, and regenerative medicine.
Pluripotency genes support research systems in which induced pluripotent stem cells provide a way to study disease-related biology in a stem-cell-based context. Researchers can also use these systems to evaluate potential therapies before considering their broader relevance. The genes are therefore valuable not only for studying cell identity, but also for connecting molecular regulation with biomedical investigation.
Their activity provides a framework for examining how cells preserve developmental potential, repress differentiation programs, and eventually move toward specialized identities. This makes pluripotency genes useful for investigating early development and the regulatory choices underlying cell fate. In biology, such studies also connect transcription-factor activity with broader questions about how cellular identities are established and maintained.
