Fig 12. Aggregation of Bristles.
The “Pre-destined Model” suggested that bristle sites can form based on patterns of expression of genes (ac and sc genes) [80]. Here sharp expression boundaries indicate bristle sites. Our simulation results show that the “Pre-destined Model” can lead to aggregation of bristles, which are not observed experimentally. For example, red circles highlight instances where ≥ 2 contacting bristle cells form aggregates.
