Cell aggregates may be useful components of artificial organs and mammalian cell bioreactors, but many cells do not naturally aggregate. In a previous r e ~o r t , ~ we described a method for promoting neural cell aggregation by addition of water-soluble conjugates of cell adhesion peptides, contain

## Abstract This study investigated the effects of poly(ethylene glycol) monoacrylate (PEGMA) on the properties of poly(ethylene glycol) diacrylate (PEGDA)β__co__βPEGMA hydrogel networks. The PEGMA materials utilized were similar to ligandβlinked materials typically copolymerized with PEGDA for use
The effectiveness of the covalent modification of a-chymotrypsin with methoxy poly(ethylene glycol) (PEG) to afford its stabilization during encapsulation in poly(lactic-co-glycolic) acid (PLGA) microspheres by a solid-in-oil-in-water method was investigated. a-Chymotrypsin was chemically modified w
## Abstract Two kinds of polylactide (PLA) which was named PLA1 with Lβlactide content of 98% and PLA2 with Lβlactide content of 88% were blended with poly(ethylene glycolβ__co__βpropylene glycol) (PEPG) in a batchwise mixer and pressed into films. The effect of annealing on the thermal properties,
