Role of Cell Morphology in Classical Delta-Notch Pattern Formation
Summary
Cell morphology influences cell fate decisions during development. Smaller cells are more likely to produce signals, impacting tissue pattern formation in multicellular organisms.
Area of Science:
- Developmental Biology
- Cell Biology
- Systems Biology
Background:
- Notch signaling is crucial for cell differentiation and pattern formation in developing organisms.
- Cell morphology, or shape, can dynamically change during development and may influence cell-cell communication.
- Understanding factors affecting intercellular signaling is key to deciphering complex developmental processes.
Purpose of the Study:
- To investigate the impact of cell morphology on mosaic pattern formation within a realistic epithelial cell model.
- To elucidate how cell shape variations affect Notch signaling and subsequent cell fate decisions.
Main Methods:
- Development of a realistic computational model of an epithelial cell layer.
- Simulation of cell-cell communication and signaling dynamics.
- Analysis of the relationship between cell area and signaling probability.
Main Results:
- Cell signaling strength was found to be inversely proportional to cell area.
- Smaller cells exhibited a higher tendency to become signal-producing cells compared to larger cells.
- Cell morphology plays a significant role in the stochastic nature of cell fate determination.
Conclusions:
- Cell morphology is a critical determinant of cell fate decisions in developing epithelial tissues.
- The inverse relationship between cell size and signaling probability contributes to fine-grained pattern formation.
- This study provides new insights into the interplay between physical cell properties and developmental signaling pathways.

03:14Notch Signaling Pathway
4.5K
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...

01:16Cell Motility through Blebbing
2.1K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

01:21Cell Polarization by Rho Proteins
2.9K
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...

01:31Mechanism of Lamellipodia Formation
2.8K
Cells migrating in response to external stimuli form lamellipodia, which are thin membrane protrusions supported by a mesh of linked, branched, or unbranched actin filaments. These actin filaments interact with myosin motor proteins, creating the dynamic actomyosin complex within the cytoskeleton. Contractility, or the ability to generate contractile stress, is inherent to the actomyosin complex. It helps cells detect the stiffness of the surrounding ECM and exert contractile force for...

01:09Cell Migration
17.4K
Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

02:19Morphogenesis
29.0K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.
