Summary
The delta/notch signaling pathway is not involved in Echinococcus stem cell division. This study investigates its role in parasite development and cell fate decisions.
Area of Science:
- Parasitology
- Developmental Biology
- Cell Signaling
Background:
- Pluripotent somatic stem cells drive Echinococcus multilocularis metacestode growth.
- Understanding stem cell maintenance and differentiation is crucial for parasite proliferation dynamics.
Purpose of the Study:
- To investigate the role of delta/notch signaling in Echinococcus cell fate decisions.
- To characterize the expression and function of delta/notch pathway components in Echinococcus larval stages.
Main Methods:
- Bioinformatic analysis of the Echinococcus genome for delta/notch pathway components.
- In situ hybridization to analyze gene expression patterns in metacestode tissue.
- EdU incorporation and pulse-chase assays to determine cell cycle status.
Main Results:
- All key delta/notch signaling components are encoded in the Echinococcus genome and expressed in larval stages.
- Delta2, Notch1, and Notch2 are expressed in distinct cells within the germinal layer.
- These components are exclusively found in post-mitotic cells, suggesting they are not involved in asymmetric stem cell division.
Conclusions:
- Delta/notch signaling does not appear to mediate asymmetric stem cell division in Echinococcus.
- These findings provide a foundation for future research on delta/notch signaling's role in parasite development and cell differentiation.

03:14Notch Signaling Pathway
4.2K
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.1K
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.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

2.2K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

01:19Cadherins in Tissue Organization
2.9K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

02:33Hedgehog Signaling Pathway
7.3K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
