3D spatial multi-omic assessment of tumors is not a luxury, it is necessary.

2D assessments of tumors are simply insufficient.

The whole field of spatial omics needs to move to 3D.

The culmination of years of hard work by Anna Maria Reuss & Co: aDISCO - a protocol for clearing & antibody-staining human formalin-fixed paraffin-embedded (FFPE) tissue! With lots of @mesospim.bsky.social #lightsheet #Microscopy @ptrrupprecht.bsky.social & many more!

We are excited to share our development of a new 10X lens with NA=0.50 over a 7.2 mm FOV and a 35 mm working distance (water), fully corrected from 400-850 nm. This lens will power our upcoming ExA-SPIM "2" and is available for dissemination - please get in touch if interested!

Are you a visionary leader in quantitative cellular imaging?

We're looking for a Director of Quantitative Cellular Imaging. This role is pivotal in our mission to demystify multicellular morphogenesis through innovative imaging assays and data analysis.

The team published LUMI v2.0! The best new feature defines ROIs on low-res 3D scout scans!

Scan your whole tissue at low resolution

Define a bounding box using something like BigStitcher

Import and scan the ROI

Take your time finding and defining an ROI without worrying about photobleaching!

After a long journey, Segment Anything for Microscopy is now published in Nature Methods! We significantly improve SAM for interactive and automatic segmentation in light and electron microscopy and build a user-friendly tool.

I used VVD Viewer for this #FluorescenceFriday video: 141 volumes from the #HHMIJanelia FlyLight Split-GAL4 #Drosophila driver collection. The animation comes from a high-level description processed by neuVid. Such a rapid tour of the data has questionable scientific value, but it's fun to watch!

I hope I never get tired of how amazing cells look in 3D. Happy Holidays and Happy #FluorescenceFriday! Here are CD45+ cells in a skin biopsy. The segmented cells and nerves at the end of the video kind of look like strings of lights

For #fluorescencefriday here is a mouse brain stained with Eosin and To-PRO-3 showing a segmented Glioblastoma in yellow. While this whole brain computational H&E staining is cool, I think I prefer TH staining for the dendrites. Imaged on Alpenglow Bioscience's 3Di #light-sheet #microscopy

Microscopy/live imaging people! Need your help 😅

I’ve only just recently started working with large time series files (1,000+ slices) and don’t know where to start when it comes to rendering and exporting them. What software(s) do you use?

Come check out the work we have been doing on 3D morphometrics using #light-sheet #microscopy!
🔬 Sneak peek! I'm presenting at Multi-Omics Brisbane 2024 on our automated 3D cell classification & segmentation system!

Let’s see how well bsky does with external media. 🧪 #Vanderbilt Neurovisualization Lab is among the first to clear, label and image an intact NHP hemisphere. Please set your player to 4K! #lightsheet #microscopy #science #brain. If your lab wants to add lightsheet to your work we can help!

Axially Swept Light-Sheet Microscopy (#ASLM) synchronizes the camera’s rolling shutter with axial remote focusing (sweeping) of the light sheet. This enables 3D imaging with a thin optical section and isotropic resolution across large FOVs. Ideal for imaging cleared tissue!
