ingression

There are three main changes that must occur within a cell to enable the process of ingression.

Within an hour of ingression, numerous transcript factors are activated.

Ingression of these cells results in formation of the mesoderm.

Changes in the adhesion properties of these cells are the best characterized and understood mechanism of ingression.

Ingression - migration of individual cells into the embryo (cells move with pseudopods)

A complicated sequence of marine ingression and isostatic rebound flooded and emptied the landscape.

The injection of a suitable label into embryonic cavities can be used to mark superficial cells lining the cavity and to follow their ingression.

Indigenous Australians hold that the number of sightings has increased alongside the increasing ingression of Europeans into the region.

However, by considering the mechanics of the process one realizes that the cell has the highest need for force generation during elongation and initial furrow ingression.

Ingression is one of the many changes in the location or relative position of cells that takes place during the gastrulation stage of animal development.

Like the Whiteheadian ingression, the "distribution without dividing" is a rethinking of the Platonic participation.

Similarly, experimentally disrupting actin-myosin contraction using inhibitors slows down ingression, but does not arrest the process.

Besides ingression, two other types of internalizing cell movements may occur during gastrulation: invagination and involution.

Prior to ingression, PMCs exhibit all the features of other epithelial cells that comprise the embryo.

Expression of the membrane protein that binds laminin, integrin, also becomes irregular at the beginning of ingression.

PT6 engines of inverted configuration for efficient protection against foreign object ingression owing to inertial separators installed inside air inlet ducts.

The use of ingression to internalize presumptive mesoderm is considered a major evolutionary change in mesoderm morphogenesis within chordates.

The first step of gastrulation is the epithelial-to-mesenchymal transition and ingression of primary mesenchyme cells into the blastocoel.

Fossils indicate that Lake Tai was dry land until the ingression of the East China Sea during the Holocene epoch.

However, the contractile force may not need to be generated in an entirely uniform manner to generate the needed forces to stabilize the ingression of the cleavage furrow cortex.

Churchill expression inhibits cell ingression leading to mesoderm formation; the cells remaining in the epiblast assume a neural fate (Sheng et al. 2003).

Transition period - Between the Baltic Ice Lake and the Yoldia Sea there was a transient lake stage before the ingression of salt water.

This process involves the ingression of mesoderm and endoderm progenitors and their migration to their ultimate position, where they will differentiate into the three germ layers.

However, during standard mitosis, the mother cell may be modeled as a simple sphere, which is deformed in the region of its equator to mimic the ingression of the furrow.

Cytoskeletal rearrangements mediate the shape changes of PMCs; though the cytoskeleton assists in the mechanics of ingression, other mechanisms drive the process.
