Biodegradable polymers are of interest for developing controlled protein drug delivery platforms. In this study, two poly (α‐hydroxy) esters were formulated with Aerosol‐OT, a surfactant stabilizer, to encapsulate the protein keratinocyte growth factor (KGF) for controlled release KGF is involved in a number of crucial biologic processes, most notably epithelial growth and repair. The concentration of KGF that caused a biological responsein vitrowas determined (optimally 10 ng/mL) and compared with the release of KGF from the two biodegradable polymer membrane formulations. Each polymer formulation released biologically relevant levels, 10 ng/mL of active KGF, although with different times release kinetics. The membrane composed of PLGA/AOT/KGF exhibited a faster release rate of KGF into solution after 120 h of degradation time than the release rate of the PLLA/AOT/KGF matrices. Cell seeding assays showed that both polymer matrices, when formulated with AOT, sustained cell growth. Time of Flight Secondary Ion Mass Spectrometry (ToF‐SIMS) was used to characterize the distribution of AOT and KGF through the polymer membrane. © 2010 Wiley Periodicals, Inc.
