Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

7.4K
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...

Cell Polarization by Rho Proteins01:21

Cell Polarization by Rho Proteins

2.8K
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,...

Notch Signaling Pathway03:14

Notch Signaling Pathway

4.4K
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...

Mechanism of Lamellipodia Formation01:31

Mechanism of Lamellipodia Formation

2.7K
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...

Cell Migration01:09

Cell Migration

17.1K
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.

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

2.2K
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...

Area of Science:

  • Theoretical biology
  • Developmental biology
  • Computational biology

Background:

  • Cellular state is determined by the epigenetic code.
  • Cellular patterns emerge from complex interactions.
  • Understanding cell-cell communication is crucial for development.

Purpose of the Study:

  • To present a conceptual model for cell patterning.
  • To explore the role of cell-cell signaling in pattern formation.
  • To analyze how different signaling types influence cell state evolution.

Main Methods:

  • Conceptual modeling of cell states and signaling.
  • Analysis of signaling based on spatial and state distances (s-distance).
  • Investigation of stabilizing, destabilizing, and non-monotonic signaling effects.

Main Results:

  • Signaling can attract or repel cells in cell state space (s-space).
  • Stabilizing signaling restores cell states after perturbations.
  • Destabilizing signaling induces alternating cell states (head-tail), and non-monotonic signaling creates cell groups.

Conclusions:

  • Different signaling mechanisms lead to diverse cellular patterns.
  • The model provides insights into the formation of complex cellular structures.
  • This framework can be applied to understand various developmental processes.
