Morphogenesis02:19

Morphogenesis

29.8K
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.

Gastrulation01:56

Gastrulation

64.6K
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...

The Phragmoplast01:59

The Phragmoplast

5.7K
Cell division is essential for organismal growth and development. In animal cells, the central spindle and its associated proteins form the midbody, a structure that has an essential role in cytokinesis. In plants, the central spindle, along with the microtubules, actin, and other cell components, matures into the phragmoplast, which is necessary for cytokinesis. Unlike the stationary midbody, the phragmoplast expands centrifugally, eventually leading to the formation of the new cell wall.

Determining the Plane of Cell Division02:13

Determining the Plane of Cell Division

3.7K
Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.

Cleavage and Blastulation01:33

Cleavage and Blastulation

49.2K
After a large-single-celled zygote is produced via fertilization, the process of cleavage occurs while zygotes travel through the uterine tube. Cleavage is a mitotic cell division that does not result in growth. With each round of successive cell division, daughter cells get increasingly smaller.

Neurulation01:30

Neurulation

44.5K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Area of Science:

  • Developmental Biology
  • Cell Biology
  • Biophysics

Background:

  • Embryonic development transforms a cell ball into an animal body plan.
  • This process requires significant cell shape changes and movements.
  • Actin and myosin contractility at cell junctions powers these morphogenetic events.

Purpose of the Study:

  • To review key morphogenetic events in animal development.
  • To discuss molecular mechanisms of cell shape change and movement.
  • To highlight conserved mechanisms across species using *Drosophila* as a model.

Main Methods:

  • Review of existing literature on developmental biology.
  • Focus on apical constriction, convergent extension, and collective cell migration.
  • Case study using *Drosophila melanogaster* for molecular insights.

Main Results:

  • Identified actin-myosin contractility as a key driver of morphogenetic events.
  • Detailed molecular mechanisms enabling cell shape change and tissue cohesion.
  • Highlighted conserved nature of these processes across diverse animal phyla.

Conclusions:

  • Morphogenetic processes like apical constriction, convergent extension, and collective cell migration are fundamental to animal development.
  • Molecular mechanisms, particularly those involving actin-myosin dynamics, are conserved.
  • Studying model organisms like *Drosophila* provides broad insights into conserved developmental strategies.
