Gastrulation01:56

Gastrulation

63.0K
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...

Morphogenesis02:19

Morphogenesis

29.2K
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.

Cells Coordinate Growth and Proliferation

4.8K
Cell size is a significant factor impacting cellular design, function, and fitness. There exists some internal coordination by which cells double their masses before division, thus, achieving homeostasis. Coordination between cell growth and proliferation depends on the checkpoints in between cell cycle phases. Loss of coordination or failure in the checkpoint mechanism can drive the cell to uncontrolled growth and loss of cellular function. Like dividing cells that coordinate cellular growth,...

Area of Science:

  • Developmental biology
  • Cell biology
  • Biophysics

Background:

  • Morphogenesis, the process of tissue form change, is crucial for animal development.
  • Genetic factors and cellular microenvironments significantly influence cell behavior.
  • Tissue geometry impacts morphogen gradients and mechanical stresses.

Purpose of the Study:

  • To investigate the role of tissue geometry in directing cellular behavior during morphogenesis.
  • To understand how macroscale tissue shape influences microscale cell activities.

Main Methods:

  • Review of existing literature on genetic and environmental factors in morphogenesis.
  • Analysis of how tissue geometry affects signaling pathways and mechanical cues.

Main Results:

  • Tissue geometry acts as both a template and an instructive cue for morphogenesis.
  • Macroscale tissue shape modulates long-range signals, including morphogen gradients.
  • Cellular responses are a result of integrated genetic information and microenvironmental cues, shaped by tissue geometry.

Conclusions:

  • Tissue geometry is a critical, underappreciated factor in developmental processes.
  • Understanding the interplay between geometry, genetics, and microenvironment is key to deciphering morphogenesis.
  • This framework aids in predicting developmental outcomes and understanding congenital abnormalities.
