The use of pro-healing proteins in regenerative medicine has become very widespread recently. One of the problems that can occur with protein release is the incorporation of the protein into the structure of the scaffold, their slow or no release, and their eventual loss of activity. Encapsulation of bioactive substances could prevent all of these problems. The thermosensitive copolymer based on poly(lactic acid), poly(glycolic acid), and poly(ethylene glycol) (PLGA–PEG–PLGA) was used in this work, mainly for the possibility of controlled degradation and gel formation at the human body temperature. The PLGA-PEG-PLGA copolymer consists of two hydrophobic segments (PLGA) and one hydrophilic segment (PEG) placed in the middle. Because of the amphiphilic properties, the copolymer self-assembles and physically cross-links into flower-shaped micelles. A thermostable 9-point mutant of fibroblast growth factor 2 (FGF2-STAB®, Enantis L.t.d.) was chosen as the bioactive component due to its ability to support the growth and the formation of new vessels.
