Cell Motility through Blebbing01:16

Cell Motility through Blebbing

Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Area of Science:

  • Bioengineering
  • Synthetic Biology
  • Soft Robotics

Background:

  • Reverse engineering biological systems requires hierarchical design across multiple scales.
  • Advances in materials science, computational design, and cellular self-organization enable recapitulating biological architecture.

Purpose of the Study:

  • To develop a systematic design strategy for reverse engineering muscular pumps.
  • To construct a biohybrid jellyfish (medusoid) as a proof of concept for this strategy.

Main Methods:

  • Utilized computer simulations and experimental data to guide design.
  • Combined chemically dissociated rat tissue with silicone polymer.
  • Mimicked jellyfish structural design, stroke kinematics, and fluid interactions.

Main Results:

  • Successfully constructed freely swimming medusoids from biological tissue and polymer.
  • Medusoid design quantitatively matched key determinants of jellyfish propulsion and feeding.
  • Demonstrated successful reverse engineering of a muscular pump.

Conclusions:

  • The developed strategy is broadly applicable for reverse engineering muscular organs.
  • This approach can be used to create simple, pumping life forms for survival.
