Morphogenesis

Morphogenesis

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.

Cellular Differentiation

Cellular Differentiation

How does a complex organism such as a human develop from a single cell? It all starts from a single fertilized egg which gives rise to a vast array of cell types, such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions.

Gastrulation

Gastrulation

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 will form...

Tissues

Tissues

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Tissues

Tissues

Tissues are a group of cells that share a common embryonic origin. Microscopic observation reveals that the cells in a tissue share morphological features and are arranged in an orderly pattern to perform specific functions. From an evolutionary perspective, tissues appear in more complex organisms. Although there are many types of cells in the human body, they are organized into four broad categories of tissues: epithelial, connective, muscle, and nervous. Each of these categories is...

Determination

Determination

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 contrast, determination...

Area of Science:

Developmental Biology
Cellular Biology
Mathematical Biology

Background:

Morphogenesis, the generation of biological shape and cellular organization, is crucial in developmental biology.
Existing models often struggle to capture the diversity of morphogenetic processes.
A unified understanding of shared features across different morphogenetic events is needed.

Purpose of the Study:

To develop a unified cellular formalism for describing diverse morphogenetic processes.
To generalize modeling possibilities by integrating the Reaction-Diffusion/Positional Information approach.
To apply this formalism to distinct biological examples.

Main Methods:

A cellular description of tissues as multi-cellular systems with emergent behavior from cell dynamics.
Modeling morphogenesis as a spatiotemporal organization of cellular activities.
Utilizing Reaction-Diffusion/Positional Information principles for generalized modeling.

Main Results:

Demonstrated a formalism unifying diverse morphogenetic processes through a cellular perspective.
Successfully applied the model to epithelial invagination, cell-cell signaling-driven differentiation, and conifer tree growth.
Showcased the flexibility of the approach across different biological scales and mechanisms.

Conclusions:

The proposed cellular formalism provides a generalized framework for studying morphogenesis.
This approach enhances the modeling capabilities for understanding tissue organization and shape generation.
It offers a unified perspective on diverse developmental biology phenomena.
