Developing fruit fly nerve cord. The glial cells (black dots) and nerve cells (brown bands) in this developing fruit fly nerve cord formed normally despite the absence of the SPITZ protein, which blocks their impending suicide. The HID protein, which triggers suicide, is also lacking in this embryo. See Fig 7C' in Bergmann et al. 2002 Dev Cell 2:159-170.
Biological Process: Nerve development
Components were identified using antibodies to specific proteins followed by immunocytochemistry to generate brown and black colors for the nerve and middle glia respectively.
