c-FOS+ cells in intact mouse brain hemisphere

c-FOS expression is an indicator of recent neural cell activity, making the detection of c-FOS+ cells a high priority for many neuroscientists. This image stack captures the hippocampus and cortex in the sagittal plane of a mouse brain left hemisphere stained with anti-c-FOS. These images were acquired with SmartSPIM at 3.6X magnification and 4 µm z-step. Scale bar 500 µm.

But ultimately, quantification is key. To complete the end-to-end tissue processing pipeline, LifeCanvas has developed SmartAnalytics, a powerful machine learning analysis tool designed for large 3D datasets. The red dots in the video above indicate the results of a c-FOS cell detection algorithm applied to the SmartSPIM image dataset. SmartAnalytics currently offers:

  • Atlas alignment
  • Cell detection
  • Fluorescence intensity quantification

and there are more applications being developed all the time! Submit a Service Request form or schedule a consultation with one of our lead scientists to learn more about this technology.
