Summary
Researchers identified surface markers to guide the resetting of human pluripotent stem cells (PSCs) to a naive state. This discovery offers a roadmap for achieving naive pluripotency in stem cell research.
Area of Science:
- Stem cell biology
- Developmental biology
- Cellular reprogramming
Background:
- Human pluripotent stem cells (PSCs) exist in primed and naive states.
- Resetting primed PSCs to the naive state is crucial for developmental and regenerative medicine applications.
- Existing protocols achieve this but lack precise cellular identification for efficient reprogramming.
Purpose of the Study:
- To identify specific surface markers on human primed PSCs that indicate susceptibility to naive state resetting.
- To provide a potential roadmap for the efficient acquisition of naive pluripotency.
Main Methods:
- Analysis of cell surface marker expression in human primed PSCs undergoing reprogramming.
- Correlation of marker expression with successful transition to the naive pluripotent state.
Main Results:
- Identification of a specific set of surface markers associated with cells capable of resetting to the naive state.
- Demonstration that these markers can predict reprogramming efficiency.
Conclusions:
- The identified surface markers serve as key indicators for selecting cells amenable to naive pluripotency induction.
- This finding facilitates a more targeted and efficient approach to generating naive human PSCs.

2.7K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

01:06Induced Pluripotent Stem Cells
5.7K
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

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...

01:51Determination
21.2K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

2.8K
The cells of the blastocyst inner cell mass only remain pluripotent for a short time. This state of pluripotency and self-renewal can be maintained in embryonic stem (ES) cell culture by adding specific chemicals or growth factors to ensure the cells can continue dividing and later differentiate into different cell types. In some cases, the cells are grown on a feeder layer of differentiated cells, which provides the growth factors and extracellular matrix components necessary for stem cell...

Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...
