Micropillar Array

ABSTRACTA cylindrical-shaped micropillar array embedded microfluidic device was proposed to enhance the dispersion of cell clusters and the efficiency of single cell encapsulation in hydrogel. Different sizes of micropillar arrays act as a sieve to break Escherichia coli (E. coli) aggregates into single cells in polyethylene glycol diacrylate (PEGDA) solution. We applied the external force for the continuous breakup of cell clusters, resulting in the production of more than 70% of single cells into individual hydrogel particles. This proposed strategy and device will be a useful platform to utilize genetically modified microorganisms in practical applications.

AbstractHuman articular cartilage is comprised of two main components, the extracellular matrix (ECM) and the pericellular matrix (PCM). The PCM helps to protect chondrocytes in the cartilage from mechanical loads, but in patients with osteoarthritis, the PCM is weakened resulting in increased chondrocyte stress. As chondrocytes are responsible for cartilage synthesis and maintenance, it is important to understand how mechanical loads affect cellular responses of chondrocytes. Many studies have examined the chondrocyte response to in vitro mechanical loading by embedding in stiff agarose. However, these experiments are mostly performed in the absence of PCM which may obscure important responses to mechanotransduction. Here, we demonstrate that drop-based microfluidics allows culture of single chondrocytes in alginate microgels for cell-directed PCM synthesis that closely mimics the in vivo microenvironment. Chondrocytes form PCM over 10 days in these single cell microenvironments. Single cell microgels and monolayer controls were encapsulated in high stiffness agarose to mimic the cartilage PCM. After physiological dynamic compression in a custom-built bioreactor, microgels exhibited distinct metabolomic profiles from both uncompressed and monolayer controls. These results demonstrate the potential of single cell encapsulation in alginate microgels to advance cartilage tissue engineering and basic chondrocyte mechanobiology.
