Summary
Researchers have identified rare 2-cell-like cells (2CLCs) in mouse embryonic stem cell (ESC) cultures. These cells offer a new model for studying totipotency in vitro.
Area of Science:
- Developmental Biology
- Stem Cell Biology
Background:
- Embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs) are key models for studying pluripotency and regenerative medicine.
- Totipotency, a state of greater developmental potential, remains less understood compared to pluripotency.
- True totipotency in mice is limited to the zygote and early 2-cell stage blastomeres.
Purpose of the Study:
- To summarize the known features of 2-cell-like cells (2CLCs).
- To provide a reference for researchers studying totipotency.
- To clarify the identity and potential of 2CLCs.
Main Methods:
- Analysis of a rare subpopulation of cells within murine ESC cultures.
- Characterization of cells exhibiting features of 2-cell embryo blastomeres.
- Biochemical and cell fate potential assessment of 2CLCs.
Main Results:
- Discovery of 2-cell-like cells (2CLCs) in mouse ESC cultures.
- These 2CLCs display characteristics of 2-cell stage blastomeres.
- 2CLCs possess expanded cell fate potential, offering a tractable in vitro model.
Conclusions:
- 2CLCs represent a significant advance in the in vitro study of totipotency.
- Further research on 2CLCs can elucidate the mechanisms underlying totipotency.
- Understanding 2CLCs is crucial for advancing regenerative medicine strategies.

The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.

45.0K
Animal and plant cells not only differ in their structure, function, and mode of nutrition but also in how they reproduce, specialize, and organize into complex structures.
Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during...

200.1K
Meiosis II is the second and final stage of meiosis. It relies on the haploid cells produced during meiosis I, each of which contain only 23 chromosomes—one from each homologous initial pair. Importantly, each chromosome in these cells is composed of two joined copies, and when these cells enter meiosis II, the goal is to separate such sister chromatids using the same microtubule-based network employed in other division processes. The result of meiosis II is two haploid cells, each...
