Microtubules in Signaling01:22

Microtubules in Signaling

The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...
Mechanism of Ciliary Motion01:05

Mechanism of Ciliary Motion

The ciliary structures were first seen in 1647 by Antonie Leeuwenhoek while observing the protozoans. In lower organisms, these appendages are responsible for cell movement, while in higher organisms, these appendages help in the movement of the extracellular fluids within the body cavities.
The cilia are made up of microtubules in a 9+2 arrangement, with nine microtubule doublet ring bundles, surrounding a pair of central singlet microtubule bundles. The doublet microtubule bundles are...
Overview Of Cell Separation And Isolation01:20

Overview Of Cell Separation And Isolation

Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.

Area of Science:

  • Developmental biology
  • Cell biology
  • Marine biology

Background:

  • Cilia traditionally known for cell motility.
  • Some cilia possess sensory or signaling roles.
  • Sea urchin embryos exhibit distinct cilia populations.

Purpose of the Study:

  • To differentiate between motile and sensory cilia in sea urchin embryos.
  • To investigate the function of long, immotile cilia in nervous system development.
  • To enable comparative studies of sensory cilia and regeneration signaling.

Main Methods:

  • Selective removal of motile cilia using a novel dillapiol derivative.
  • Comparative investigation of remaining immotile cilia.
  • Utilizing deciliated embryos for regeneration studies.

Main Results:

  • Distinguished short motile cilia from long, immotile cilia.
  • Observed immotile cilia in a region associated with nervous system development.
  • Successfully isolated putative sensory cilia for further study.

Conclusions:

  • Sea urchin embryos possess functionally distinct cilia types.
  • Immotile cilia are linked to directional swimming and nervous system origins.
  • The novel dillapiol derivative is effective for selective cilia manipulation in research.
