New Low-Cost Light-Sheet Microscope Improves Access to Technology

Researchers from Juntendo University in Japan have created an innovative, affordable 3D imaging system that promises to accelerate biomedical research. The new system, called descSPIM (desktop-equipped Selective Plane Illumination Microscopy for cleared specimens), addresses the longstanding issue of high costs and complexity associated with Light Sheet Fluorescence Microscopy (LSFM) systems.

The team, led by Professor Etsuo A. Susaki, has successfully reduced the cost of their LSFM system to between $20,000 and $50,000, making it more than ten times less expensive than commercial alternatives. This significant price reduction, coupled with a user-friendly design, aims to make advanced 3D imaging technology more accessible to researchers worldwide.

DescSPIM incorporates several unique features, including a glass cuvette replacing the medium chamber and a two-stage synchronization process during imaging. These innovations, along with streamlined data capture and image conversion processes, have substantially reduced overall imaging time.

The system's effectiveness has been demonstrated through various applications, including 3D visualization of cleared tissues and organs. Notably, descSPIM successfully imaged whole-brain samples of transgenic mice with cellular resolution and enabled 3D imaging of entire tumor masses in cancer cell line-derived xenograft models.

Kohei Otomo, first author of the paper published in Nature Communications, emphasized the system's open-source nature, stating, "Its user-friendly construction and open-sourced nature foster a collaborative environment conducive to the development of pioneering imaging technologies."

The descSPIM system has already garnered global interest, with researchers utilizing it for diverse projects ranging from detailed organ imaging to investigating cancer metastasis. Professor Susaki highlighted the system's potential impact, saying, "When I recognized this bottleneck, I wanted to develop an affordable and sufficiently performing light-sheet microscopes to enhance accessibility in biomedical research."
