Stereotype Content Model02:16

Stereotype Content Model

15.4K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Embryonic Stem Cells00:58

Embryonic Stem Cells

32.3K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Measurement of Air Content in Concrete

621
Air content measurement in concrete is critical for ensuring structural integrity and durability of concrete structures, especially in environments prone to severe weather conditions. Accurate air content analysis optimizes concrete's resistance to freeze-thaw cycles and enhances its workability and strength. Several methods are standardized under ASTM guidelines to measure the air content in fresh concrete, each suitable for different concrete types and conditions.
The pressure method,...

Seed Structure and Early Development of the Sporophyte02:33

Seed Structure and Early Development of the Sporophyte

31.0K
Seed structures are composed of a protective seed coat surrounding a plant embryo, and a food store for the developing embryo. The embryo contains the precursor tissues for leaves, stem, and roots. The endosperm and cotyledons—seed leaves—act as the food reserves for the growing embryo.

Ribosome Profiling02:24

Ribosome Profiling

4.2K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Distribution of Cytoplasmic Content02:33

Distribution of Cytoplasmic Content

4.7K
Cytokinesis segregates a cell’s chromosomes and organelles into its daughter cells. Organelles divide and grow prior to cell division but cannot be synthesized de novo; therefore, cells must receive at least one copy of each organelle to survive. Currently, many of the details of how the organelles are distributed are not yet fully elucidated.
Distribution of cytoplasmic determinants
The cytoplasm contains various organelles, as well as salts, proteins, and water. The distribution of...

Area of Science:

  • Developmental Biology
  • Genetics
  • Cell Biology

Background:

  • The Caenorhabditis elegans embryo is a key model for studying cell fate specification and tissue morphogenesis.
  • Existing lineage-tracing methods are labor-intensive and lack integrated morphogenetic readouts.

Purpose of the Study:

  • To develop a high-content method for rapid classification of developmental phenotypes.
  • To enable simultaneous live imaging and analysis of multiple embryos.
  • To facilitate the study of genes involved in cell fate and morphogenesis.

Main Methods:

  • Developed two custom Caenorhabditis elegans strains: one for germ layer markers and another for morphogenesis markers.
  • Established a procedure for simultaneous live imaging of 80-100 embryos.
  • Created a custom program for automated image processing and analysis of individual embryos.
  • Utilized RNA interference (RNAi) to perturb 40 developmental genes.

Main Results:

  • Generated distinct and reproducible phenotypic signatures for a wide range of developmental genes.
  • Successfully classified phenotypes related to both cell fate specification and morphogenesis.
  • Provided new in vivo evidence for MBK-2 in mesoderm fate specification.
  • Provided new in vivo evidence for LET-381 in embryonic elongation.

Conclusions:

  • The developed high-content method significantly accelerates the classification of developmental phenotypes in C. elegans embryos.
  • This approach offers a powerful tool for dissecting gene function in cell fate and morphogenesis.
  • The study identified novel roles for MBK-2 and LET-381 in specific developmental processes.
