Tissue Clearing Applications

Breast Cancer

Tissue Clearing Breast Cancer

ClearLight has performed tissue clearing on breast cancer and has extensive expertise in three-dimensional imaging and quantitative analysis of CLARITY processed breast cancer tissues.

Video of breast cancer tissue that was cleared using CLARITY protocol then immunostained with antibodies against pan-CK (green), Ki67 (yellow), CD3 (red), and a DAPI nuclear counterstain (blue).

Comparison of 3D Volume Merged View and 2D Optical Slice Section

Demonstrates Staining Uniformity and Visible Cell Classification

Tissue Clearing Breast Cancer
Biopsy Samples

The CLARITY process was performed on previously fixed breast cancer core needle biopsy samples. Imaging on a confocal microscope (25x) clearly demonstrates how the tumor microenvironment is preserved. The 3D volume is shown in a merged view (left), with a 2D optical slice section (right) from the same volume that demonstrates the staining uniformity and visible cell classification. Subcellular staining was observed throughout these thick tissue sections. The breast tissue was immunostained with pan-CK (green), Ki67 (yellow), CD3 (red), and a DAPI nuclear counterstain (blue).

If we took 2D optical sections from our 3D images, we find that the 2D slice view that we were able to get with CLARITY was comparable to the FFPE slides, meaning that when scored by pathologists, both processes got comparable results.

 

Award Winning Breast Cancer Study

 Collaborative Research Organization for Tissue Clearing Tonsil and Tru3D Tissue Analysis

Leverage our Internal R & D

When you work with us you gain the benefit of our internal experiments, assessments, and rigorous testing. In addition to performing our lab services: CLARITY Tissue Clearing, 3D IHC, and Tru3D Tissue Analysis, ClearLight scientists perform internal Research and Development to advance our understanding and applications of CLARITY to other tissue types and downstream applications. Researchers who work with us benefit from this exploratory work. The ClearLight “lab basement” is full of failed or pivoted experiments that helped inform our path to arrive at what does work. Work with us to avoid making the same mistakes that we have made or going down the blind alleys that we’ve pivoted away from.

“If you don’t want to spend the time figuring it out, we can help. We work hard to make this look easy.” - Dr. Sharla White, VP of Research and Development
