Dynamic stem cell states: naive to primed pluripotency in rodents and humans

Area of Science:

• Stem cell biology
• Molecular mechanisms of cell reprogramming

Background:

• Pluripotent stem cells (PSCs) exist in distinct states, notably naive and primed.
• Understanding PSC state regulation is crucial for regenerative medicine and developmental biology.

Purpose of the Study:

• To review recent advances in isolating and characterizing naive and primed pluripotent stem cell states.
• To provide an overview of molecular pathways governing pluripotent state transitions and interconversion.
• To highlight future research directions and potential applications of dynamic pluripotent cell states.

Main Methods:

• Integration of recent discoveries on pluripotent stem cell states.
• Overview of signalling pathways regulating pluripotency.
• Comparative analysis across different species.

Main Results:

• Identification of unique naive and primed pluripotent stem cell states with distinct characteristics.
• Elucidation of pathways underlying pluripotent state transitions in vitro and in vivo.
• Insights into direct reprogramming of somatic cells into pluripotent states.

Conclusions:

• Dynamic pluripotent cell states offer significant potential for novel applications.
• Further research is needed to address key unresolved questions in pluripotency regulation.
• Understanding and manipulating these states can advance regenerative medicine.
