Human Cortical Neuronal Cells (HCN-1A Line)
The monolayer human cortical neuronal cell culture presented in the digital image above was labeled for the cytoskeletal filamentous actin and intracellular mitochondrial networks with Alexa Fluor 488 conjugated to phalloidin and MitoTracker Red CMXRos, respectively. Nuclei present in the cells were counterstained with the DNA-selective bisbenzimide dye, Hoechst 33258. Images were recorded in grayscale with a 12-bit digital camera coupled to either a Nikon E-600 or Eclipse 80i microscope equipped with bandpass emission fluorescence filter optical blocks. During the processing stage, individual image channels were pseudocolored with RGB values corresponding to each of the fluorophore emission spectral profiles.
