This image mainly shows the nurse cells in egg chambers of adult female fruit flies. The nurse cells surround the relatively small oocytes, synthesizing and depositing nutrients (proteins/RNAs, etc.) into oocytes to support their development. The majority of germ cells in female fruit flies are actually nurse cells, which play an essential “nursing role” to less abundant oocytes.

I took those images to compare female germline development in different genotypes, especially focusing on if the mutation of certain genes would impact this process.
