The loading and release profiles of Apt19s and BMP2. (A) Confocal microscopy images of the PCL/SIS scaffold modified with Apt19s and pBMP2. The upper line showed the confocal microscopy images of the PCL/SIS scaffold without Apt19s (a1), modified 2 nmol (a2) and 4 nmol (a3) of rhodamine-labeled Apt19s. The upper line showed the confocal microscopy images of the PCL/SIS scaffold without pBMP2 (a4), modified 1 μg (a5) and 2 μg (a6) of FITC-labeled pBMP2. (B–C) In vitro release profiles of Apt19s and BMP-2 from scaffolds of PCL/SIS-pBMP2-Apt and PCL/SIS-BMP2-Apt.
