  • To ensure compatibility with downstream molecular analyses, including next-generation DNA sequencing.

Main Methods:

  • Development of a novel mesodissection platform.
  • Utilizing a microfluidic tool for tissue extraction from formalin-fixed paraffin-embedded (FFPE) slides.
  • Automated method for isolating histological regions of interest.

Main Results:

  • The platform retains advantages of laser dissection while offering speed and ease similar to manual methods.
  • Demonstrated rapid extraction of histological regions from FFPE tissue.
  • The method is compatible with downstream enzymatic reactions and next-generation DNA sequencing protocols.

Conclusions:

  • The presented mesodissection platform provides an efficient and automated solution for high-resolution tissue dissection.
