HyClear: A Novel Tissue Clearing Solution for One-Step Clearing of Microtissues

Area of Science:

• Biotechnology
• Cell Biology
• Drug Discovery

Background:

• 3-D cell cultures better mimic in vivo tissues for drug screening.
• Limitations in 3-D microscopy (light scattering) restrict imaging depth to 100-200 µm.
• Existing tissue clearing protocols are not suitable for small spheroids and organoids.

Purpose of the Study:

• To develop a novel, rapid tissue clearing solution for small 3-D cell cultures.
• To enable deeper imaging and improve data quality in drug screening experiments.
• To create a protocol compatible with high-throughput screening.

Main Methods:

• Development of a one-step tissue clearing solution (HyClear) using DMSO, HPG, and urea.
• Application of HyClear to small spheroids and organoids.
• Comparison of HyClear with existing tissue clearing agents.

Main Results:

• HyClear enables efficient one-step clearing of spheroids and organoids.
• The protocol is rapid, simple, and compatible with high-throughput screening.
• HyClear demonstrates superior performance compared to commonly used clearing agents.
• Improved data quality was achieved in drug screening experiments using HyClear.

Conclusions:

• HyClear is an effective and versatile tissue clearing solution for small 3-D cell cultures.
• This method overcomes limitations of traditional 3-D microscopy for drug screening.
• HyClear facilitates enhanced data acquisition and analysis in cancer biology research.
