Umbilical cord tissue is a rich, ethically unproblematic source of mesenchymal stromal cells (MSCs).
Mechanical dissociation with the TissueGrinder enables fast, standardized isolation without enzymes – maintaining viability and surface characteristics for robust culture and downstream analysis.

Fresh umbilical cord segments are mechanically dissociated in the TissueGrinder (100 µm filter). Cells are pelleted and seeded for MSC culture expansion (P1–P3). The study used porcine cords as a model analogous to human tissue.
Cells isolated with the TissueGrinder adhered and proliferated through multiple passages (P1–P3), displayed typical spindle-shaped MSC morphology, and reached confluence within days. Mechanical dissociation preserved high viability and yielded performance comparable or superior to enzymatic digestion.
