Summary
Scientists discovered new nanotubular structures enabling direct cell-to-cell communication. These structures transfer organelles, suggesting a novel mechanism for multicellular organism development and maintenance.
Area of Science:
- Cell Biology
- Molecular Biology
- Developmental Biology
Background:
- Multicellular organisms rely on cell-to-cell communication for development and maintenance.
- Existing communication methods include chemical synapses, gap junctions, and plasmodesmata.
Purpose of the Study:
- To describe novel nanotubular structures facilitating intercellular communication.
- To investigate the functional role of these structures in cellular exchange.
Main Methods:
- Observation of de novo nanotubular structure formation between cells.
- Analysis of the transfer of membrane vesicles and organelles through these structures.
- Assessment of the passage of small molecules across the nanotubular connections.
Main Results:
- Highly sensitive nanotubular structures form complex networks between cells.
- These structures selectively transfer membrane vesicles and organelles.
- The flow of small molecules appears to be impeded by these nanotubular connections.
Conclusions:
- A novel biological principle of cell-to-cell interaction is proposed.
- This principle is based on membrane continuity and intercellular organelle transfer.
- These findings offer new insights into multicellular development and tissue maintenance.

01:35Microtubules
There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.Microtubules are hollow tubes whose walls are made up of globular tubulin proteins. Each tubulin...
01:18Microtubules
Microtubules are the thickest cytoskeletal filaments with a diameter of 25 nm. In prokaryotic organisms, microtubules are commonly found in locomotory appendages like cilia and flagella. In eukaryotic cells, microtubules form specialized extensions for moving fluid over the surface, like those found in cells lining the intestine.
Microtubules have two structurally similar globular protein subunits: α and β tubulins. In the cytosol, the α and β tubulins form a heterodimer. These αβ-heterodimers...

01:43The Movement of Organelles and Vesicles
In eukaryotic cells, cytoskeletal filaments such as actin, microtubules, and intermediate filaments form a mesh-like cytoskeletal network. These filaments serve as tracks for transporting cellular cargo. Specialized motor proteins use the chemical energy stored in adenosine triphosphate (ATP) for this transport. During interphase, microtubules are polarized, with the plus-end towards the cell periphery and the minus-end towards the cell center. Two microtubule-associated motor proteins,...
01:24Microtubules in Cell Motility
Microtubules are thick hollow cylindrical proteins that help form the cytoskeleton. Microtubules have varied roles in the cell. These filaments help form cellular appendages like cilia and flagella, which are responsible for locomotion. The cilia arise from basal bodies, separated from the main body by a membrane-like structure forming the transition zone. This zone is the gate for the entry of lipids and proteins, creating a unique composition of lipids and proteins in the ciliary membrane and...
01:26Transport Across the Golgi
While it is unclear how molecules move between adjacent Golgi cisternae, it is apparent that the molecules move from cis- cisterna, the entry face, to the trans- cisterna, the exit face. Experiments initially suggested vesicles that bud from one cisterna and fuse with the next cisterna to transport proteins between the cisternae. This vesicular transport model describes the Golgi apparatus as a relatively static structure with a unique enzyme composition in each cisterna. Molecules are...
