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...

Cell Migration

Cell Migration

Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Background:

The Waddington landscape visually represents cell differentiation potential but reconstructing it dynamically remains challenging.
Current models often lack dynamical interpretations crucial for understanding cell fate transitions.
Characterizing differentiation potential typically relies on transcriptomic signatures of known markers.

Purpose of the Study:

To develop a feasible framework for calculating dynamically interpretable energy indicators to reconstruct the Waddington landscape.
To provide dynamical interpretations for cell fate transitions, enhancing understanding beyond static representations.
To amalgamate diverse cell fate transitions into a unified Waddington landscape.

Main Methods:

Utilized sparse autoencoders and the reaction-diffusion-advection equation to model cell migration and proliferation.
Developed a framework for calculating dynamically interpretable energy indicators.
Dynamically simulated and reconstructed Waddington landscapes for various developmental processes.

Main Results:

Successfully reconstructed Waddington landscapes for hematopoiesis and reprogramming processes.
Dynamically simulated and reconstructed landscapes for embryogenesis and Epithelial-Mesenchymal Transition.
Amalgamated diverse cell fate transitions, including typical and special developmental processes, into a unified Waddington landscape.

Conclusions:

The developed framework provides a dynamically interpretable method for Waddington landscape reconstruction.
This approach enhances the understanding of cell fate transitions by integrating migration and proliferation dynamics.
The unified Waddington landscape offers a comprehensive model for various cell developmental processes.
