Area of Science:

  • Biotechnology
  • Cell Biology
  • Microfluidics

Background:

  • Current solid tissue-to-cell isolation methods are invasive, manual, and inefficient, leading to significant cell loss, especially for rare cell types.
  • Existing lab-on-chip platforms offer only partial tissue processing and require off-chip steps, limiting their clinical utility.

Purpose of the Study:

  • To develop and validate the first microfluidic platform capable of complete, integrated dissociation of native biological tissues into single, ready-to-use cells.
  • To improve cell yield and viability for cell-based therapeutic applications.

Main Methods:

  • Development of a microfluidic platform integrating tissue dissociation, debris filtration, cell sieving, washing, and staining.
  • Testing the platform's performance on diverse biological tissues.

Main Results:

  • The microfluidic platform successfully dissociated native tissues into single cells, ready for immediate culture.
  • Achieved a higher yield of viable single cells (2262 cells/ml/mg) compared to conventional methods (1233.25 cells/ml/mg).
  • The streamlined process minimizes cell loss and operator dependency.

Conclusions:

  • This microfluidic platform represents a significant advancement in sample preparation for cell-based therapeutics.
  • The integrated, automated system enhances efficiency and cell yield, paving the way for improved clinical applications.
