High titer (>10 g/L) monoclonal antibody (mAb) cell culture processes are typically achieved by maintaining high viable cell densities over longer culture durations. A corresponding increase in the solids and sub-micron cellular debris particle levels are also observed. This higher burden
The pericellular matrix (PCM) surrounding chondrocytes is thought to play an important role in transmitting biochemical and biomechanical signals to the cells, which regulates many cellular functions including tissue homeostasis. To better understand chondrocytes interactions with their PCM, three-dimensional poly(ethylene
Ultrasound has potential as a non-destructive analytical technique to provide real-time online assessments of matrix evolution in cell-hydrogel constructs used in tissue engineering. In these studies, chondrocytes were encapsulated in poly(ethylene glycol) hydrogels, and gel degradation was manipulated to provide
