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...

Somatic to iPS Cell Reprogramming

2.0K
Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Determining the Plane of Cell Division02:13

Determining the Plane of Cell Division

2.7K
Positioning the cell division plane is a critical step during development and cell differentiation, particularly during mitosis when the plane is essential for determining the size of the two daughter cells. The cell division plane is perpendicular to the plane of chromosome segregation, but different types of organisms have different cell division mechanisms to suit their morphology and function.

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...

Area of Science:

  • Developmental Biology
  • Computational Biology
  • Genetics

Background:

  • Caenorhabditis elegans vulval development is a key model for studying cell differentiation during organogenesis.
  • Cell fate in vulval development is regulated by the interplay of LET-23 and Notch signaling pathways.
  • State-based models and formal analysis are powerful for predicting mutation outcomes but can be computationally intensive.

Purpose of the Study:

  • To develop a faster computational method for predicting cell fate patterns in C. elegans vulval development.
  • To enable the inference of compatible genomes from observed cell fate patterns.
  • To provide a platform for analyzing experimental data and designing future experiments.

Main Methods:

  • Derived logic programs from state machines describing vulval precursor cell differentiation.
  • Utilized formal analysis techniques for computational prediction.
  • Applied the method to predict cell fate patterns from dig-1 mutations and let-23 mosaics.

Main Results:

  • Achieved a four-orders-of-magnitude increase in prediction speed compared to previous methods.
  • Successfully inferred compatible genomes from cell fate patterns.
  • Predicted highly variable cell fate patterns resulting from specific genetic mutations and mosaics.

Conclusions:

  • Logic programs derived from state machines offer a significant speedup for modeling cell fate determination.
  • The developed technique allows for retrodiction of genotypes from phenotypes, advancing genetic analysis.
  • This approach serves as a valuable platform for experimental design and data analysis in developmental biology.
