Analysis of Cell Migration within a Three-dimensional Collagen Matrix
Published on: October 5, 2014
Abstract:
"The paper analyzes some problems related to the census measurement of internal migration according to the three following aspects: The lack of agreement between the proposed objectives and the type of question made; questionnaire design errors and enumeration errors; and inadequate data elaboration." The geographic focus is on Latin America. Problems concerning data on place of birth or place of previous residence and how these can affect the calculation of migration trends are considered.

Migration
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.
Cell 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.
Cell 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.
