Gastrulation01:56

Gastrulation

65.0K
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...

Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

3.8K
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.

Cell Migration01:19

Cell Migration

6.2K
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 Migration01:09

Cell Migration

18.2K
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.

Determination01:51

Determination

20.5K
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

Mechanism of Lamellipodia Formation01:31

Mechanism of Lamellipodia Formation

3.4K
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...

Area of Science:

  • Developmental biology
  • Cellular mechanics
  • Tissue morphogenesis

Background:

  • Understanding developmental mechanisms requires studying tissue deformations and flows.
  • Mechanical coupling between adjacent tissues influences their behavior.
  • This phenomenon is analogous to chemical induction in developmental processes.

Purpose of the Study:

  • To propose and define the term "mechanical induction."
  • To review in vivo examples of mechanically induced epithelial flow and planar deformation.
  • To discuss factors influencing mechanical induction and morphogenesis.

Main Methods:

  • Literature review focusing on in vivo studies.
  • Analysis of mechanical coupling in developmental processes.
  • Integration of tissue and inter-tissue scale perspectives.

Main Results:

  • Mechanical induction is a key process in morphogenesis.
  • Neighboring tissue activity can drive deformation and flow in adjacent regions.
  • Competence factors modulate the extent of induced morphogenesis.

Conclusions:

  • Mechanical induction is a crucial concept for understanding how tissues develop.
  • Integrating multiple tissue scales is essential for a comprehensive view of morphogenesis.
  • Further research into mechanical induction will illuminate developmental processes.
