Evaluation of smooth muscle cell response using two types of porous polylactide scaffolds with differing pore topography.

The goal of tissue engineering is to create bioartificial tissues for the replacement of failed or nonfunctional tissue. Porous tissue-engineered scaffolds may be created through a solvent-casting/porogen-leaching technique. Almost exclusively, sodium chloride (NaCl) is the porogen of choice.

Characterization of cellular carriers for use in injectable tissue-engineering composites.

Injectable composite tissue-engineering scaffolds are systems that incorporate individual cell carriers within a gel delivery matrix. This study assessed low-temperature casting as a possible method to produce synthetic cell-carrier beads. Porous poly-L-lactide beads were manufactured by low-temperature casting.
