Summary
Epsins regulate endocytosis and are crucial for mouse embryonic stem cell (mESC) differentiation. Knockdown of epsin1/2 impairs neural progenitor development and Notch signaling, highlighting epsins
Area of Science:
- Cell Biology
- Developmental Biology
- Stem Cell Biology
Background:
- Epsins are key proteins in clathrin-mediated endocytosis, a fundamental cellular process.
- Mouse embryonic stem cells (mESCs) possess unique pluripotency and differentiation capabilities.
Purpose of the Study:
- To investigate the role of epsins in mESC pluripotency exit and neural differentiation.
- To elucidate the impact of epsin1/2 knockdown on neural progenitor development and Notch signaling.
Main Methods:
- Epsin1/2 knockdown in mESCs using RNA interference.
- Analysis of mESC pluripotency, differentiation, and neural progenitor morphology.
- Assessment of Notch signaling pathway activity.
Main Results:
- Epsin1/2 knockdown altered mESC exit from pluripotency and differentiation.
- Impaired polarization and division of mESC-derived neural progenitors were observed.
- Notch signaling was compromised, and its restoration rescued epsin-mediated phenotypes.
Conclusions:
- Epsins are essential for controlling mESC exit from pluripotency.
- Epsins facilitate neural differentiation by modulating Notch signaling pathways.

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...

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).

Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.4K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
