Biphasic organo-bioceramic fibrous composite as a biomimetic extracellular matrix for bone tissue regeneration

摘要

In bone tissue engineering, the organo-ceramic composite, electrospun polycaprolactone/hydroxyapatite (PCL/HA) scaffold has the potential to support cell proliferation, migration, differentiation, and homeostasis. Here, we report the effect of PCL/HA scaffold in tissue regeneration using human mesenchymal stem cells (hMSCs). We characterized the scaffold by fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), scanning electron microscope (SEM) and assessed its biocompatibility. PCL/HA composite is superior as a scaffold compared to PCL alone. Furthermore, increasing HA content (5–10%) was more efficacious in supporting cell-scaffold attachment, expression of ECM molecules and proliferation. These results suggest that PCL/HA is useful as a scaffold for tissue regeneration.
