The Role of Cell Shape in Directing Cell Division

Recent research has unveiled a fascinating aspect of cell division that involves the utilization of cell shape to determine the fate of offspring cells. This discovery holds significant implications for tissue engineering and enhances our comprehension of cancer metastasis.

Traditionally, it was believed that most cells adopt a spherical shape prior to division to facilitate equal distribution of cellular contents between the resulting daughter cells, ensuring the generation of identical cell types.

However, stem cells defy this norm by undergoing an asymmetric division, giving rise to two distinct cell types. Building on this concept, a study conducted by Shane Herbert and his team at the University of Manchester revealed that non-stem cells, specifically endothelial cells in zebrafish embryos, also exhibit asymmetric division while forming new blood vessel branches.

The researchers observed that the shape of human endothelial cells before division directly correlated with the symmetry of the division. Cells that were elongated and slender were more likely to undergo asymmetric division, indicating that cells can modulate their division based on their shape.

This unique mechanism allows cells to retain information about their structure and behavior, enabling them to preserve their characteristics even during division. Consequently, cells can continue their functions uninterrupted, simultaneously migrating, dividing, and generating diverse cell types to meet the dynamic requirements of tissue development.

Furthermore, this discovery has significant implications for tissue regeneration as manipulating cell shapes could offer a novel approach to generating specific cell types essential for growing functional tissues. Additionally, the insights gained from this research could shed light on the migratory behavior of cancer cells and their role in metastasis.

According to Buzz Baum from the MRC Laboratory of Molecular Biology in Cambridge, this study exemplifies how organisms can adapt mechanisms like cell rounding to perform diverse functions required for tissue sculpting. By maintaining essential information while expanding cell networks, cells demonstrate a sophisticated strategy for efficient growth and differentiation.
