Morphogenesis02:19

Morphogenesis

30.0K
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

65.2K
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...

Neurulation01:30

Neurulation

44.8K
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...

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...

Zygotic Development And Stem Cell Formation01:10

Zygotic Development And Stem Cell Formation

6.3K
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...

Cell Migration01:09

Cell Migration

18.3K
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.

Area of Science:

  • Developmental Biology
  • Theoretical Biology
  • Computational Biology

Background:

  • Understanding the mechanisms driving embryonic development and morphogenesis is a fundamental challenge in biology.
  • Current models often struggle to integrate cellular behavior with emergent macroscopic structures.

Purpose of the Study:

  • To develop a theoretical model that predicts cell fate and embryonic development based on cellular epigenetic information.
  • To formalize the concept of cell potency within a predictive framework for morphogenesis.

Main Methods:

  • Development of a theoretical model based on the epigenetic code of individual cells and their neighbors.
  • Utilizing epigenetic spectra to determine cell events and predict collective cell behavior.
  • Formalizing and analyzing the properties of cell potency.

Main Results:

  • The model successfully describes cell fate determination within a developing organism.
  • It enables the prediction of tissue, organ, and overall embryo shapes from the zygote stage.
  • The formalized concept of cell potency provides new insights into developmental plasticity.

Conclusions:

  • The proposed epigenetic code model offers a unified approach to understanding and predicting morphogenesis.
  • This theoretical framework has the potential to simulate and analyze embryonic development across different scales.
  • The formalization of cell potency is a key component for advancing predictive models in developmental biology.
