The Sticky Challenges of Bioprocessing

Cell-to-cell adhesion of mammalian cells is what cells are supposed to do, but can be quite detrimental to bioprocessing, upstream and downstream, by producing cell clumps with later formation of larger clusters. Single cell suspensions, microcarrier-adherent cells and stem cell aggregates demonstrate this behaviour. How do we prevent something natural from occurring? The typical workaround …

Here’s why we are still “attached” to adherent cells

Except for hematopoietic-derived cells, most cells isolated from animals are naturally adherent. In vivo, adherent cells interact with their surrounding environment and with each other in order to remain viable and exercise their specific function. Indeed, the intracellular signalling cascades that influence the cells’ morphology, growth, phenotype and final fate are governed by the cells’ …
