Embryonic stem cells (ESCs) can become 2-cell-like cells (2CLCs), which are totipotent-like. Understanding the molecular regulators of 2CLCs and chemically induced totipotent cells aids regenerative medicine.
Area of Science:
- Developmental Biology
- Stem Cell Biology
- Epigenetics
Background:
- Embryonic stem cells (ESCs) possess pluripotency, self-renewal, and differentiation capabilities.
- A subset of mouse ESCs, 2-cell-like cells (2CLCs), mimic the totipotent state of early embryos.
- 2CLCs are crucial models for studying totipotency establishment.
Purpose of the Study:
- To review molecular regulations governing 2CLCs.
- To summarize chemical manipulations for inducing totipotent-like cells.
- To provide a foundation for understanding totipotency regulatory networks.
Main Methods:
- Review of existing literature on 2CLCs and totipotent cell induction.
- Analysis of transcriptomic signatures of 2CLCs.
- Examination of regulatory factors (transcription factors, epigenetic modifications, RNA regulators).
Main Results:
- 2CLCs exhibit a transcriptomic profile similar to the 2-cell embryonic stage.
- Various regulators, including transcription factors and epigenetic modifiers, are involved in ESC reprogramming to 2CLCs.
- Chemical treatments can induce and maintain alternative totipotent-like cell types.
Conclusions:
- Molecular insights into 2CLCs are advancing the understanding of totipotency.
- Chemically induced totipotent cells offer potential for regenerative medicine.
- Further research into regulatory networks is essential for harnessing totipotency.
