Determination

16.3K
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...

Zygotic Development And Stem Cell Formation

6.4K
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...

Area of Science:

  • Neuroscience
  • Developmental Biology
  • Artificial Intelligence

Background:

  • Infant neurodevelopment is critical, with many disorders originating from abnormal brain development.
  • Existing methods for predicting neurodevelopmental trajectories from incomplete data have limitations in flexibility and consistency.
  • Current deep learning models often predict missing data independently, ignoring longitudinal dependencies.

Purpose of the Study:

  • To develop a novel framework for predicting individualized longitudinal cortical developmental trajectories from incomplete infant neurodevelopmental data.
  • To address the limitations of existing regression and deep learning models in handling incomplete longitudinal data.
  • To improve the understanding of normal early brain development and aid in the identification of neurodevelopmental disorders.

Main Methods:

  • Developed a longitudinally consistent triplet disentanglement autoencoder (LCTDA) framework.
  • Employed a surfaced-based autoencoder to disentangle identity-related and age-related features.
  • Utilized dynamic time-warping loss to ensure temporal consistency and similarity among predicted trajectories.

Main Results:

  • The LCTDA framework demonstrated superior longitudinal consistency and exactness in predicting infant cortical property maps.
  • The model successfully generated individualized longitudinal developmental trajectories.
  • Experimental results validated the framework's effectiveness compared to existing baseline methods.

Conclusions:

  • The proposed LCTDA framework offers a flexible and temporally consistent approach for predicting neurodevelopmental trajectories from incomplete data.
  • This method enhances the ability to study normal early brain development and detect neurodevelopmental disorders.
  • The disentanglement of identity and age features allows for more accurate and individualized predictions.
