Migratory Behavior of Cells Generated in Ganglionic Eminence Cultures
Published on: April 21, 2011
Summary
Internal migration patterns in France are shaped by regional origins and evolving urbanization. Individual mobility choices reflect territorial characteristics and historical urban development over fifty years.
Area of Science:
- Demography
- Human Geography
- Sociology
Context:
- Analyzes internal migration trends in France using data from the 1981 Triple Biographie survey by INED.
- Examines lifetime migration behavior influenced by regional origins and territorial characteristics.
Purpose:
- To understand the factors influencing the distance and degree of individual mobility within France.
- To investigate the impact of urbanization and urban network evolution on migration patterns.
Summary:
- Individual migration behavior is significantly influenced by regional origins and the specific characteristics of their territories.
- The ongoing process of urbanization and the changing urban network over the past 50 years are key determinants of migration patterns.
Impact:
- Provides insights into the spatial dynamics of French population redistribution.
- Highlights the interplay between individual choices, regional factors, and large-scale societal changes like urbanization.

01:56Gastrulation
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata will form...
01:09Cell Migration
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.
00:53Migration
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.
02:39Gene Flow
Gene flow is the transfer of genes among populations, resulting from either the dispersal of gametes or from the migration of individuals.
01:19Cell Migration
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
01:21Chemotaxis and Direction of Cell Migration
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon towards...
