A two-dimensional microarray of 10 000 (100 × 100) chondrocyte spheroids was constructed with a 100 μm spacing on a micropatterned gold electrode that was coated with poly(ethylene glycol) (PEG) hydrogels. The PEGylated surface as a cytophobic region was regulated by controlling the gel structure through photolithography. In this way, a PEG hydrogel was(More)
Functional proteins like antibody, cytokine and growth factor have been widely used for basic biological research, diagnosis and cancer therapy. Particularly, antibody drugs as attractive biopharmaceuticals will be expected to create an enormous new market. Chinese hamster ovay (CHO) cells are being increasingly used in industry for the production of(More)
