This can occur by chance if the marked cell is pushed away from the niche by the divisions of neighboring stem cells. In the root, evidence that stem cells are maintained by intercellular signals ...

These physical signals are determined by the strength of intercellular contacts, the E-cadherin junctions. Moreover, they showed that cells are extruded either apically or basally into the tissue ...

Cells communicate with one another during development ... Formation of recurring transient Ca 2+ -based intercellular ...

Mechanical intercellular forces determine the fate of extruding cells Cells within epithelial monolayers exert forces on their neighbors, which can trigger cell detachment and subsequent elimination.
