General Information
Term five-cell ommatidial precursor cluster ID (Ontology) FBbt:00001771 (Fly Anatomy)
Definition Ommatidial precursor cluster composed of five photoreceptor precursor cells; R8, R2, R5, R3 and R4. This precursor cluster is formed when the mystery cells leave the cluster to rejoin the surrounding, unpatterned epithelium. The nuclei of the remaining cells rise apically whereas the nuclei of the surrounding cells descend.[ FlyBase:FBrf0064789 ]
Also Known As "five-cell ommatidial precursor"
