, PCL scaffolds retained fiber alignment and preserved their volume throughout the evaluation, showing minimal structural alteration. In contrast, PCL + BG5% scaffolds showed more visible structural changes at 28 days. Despite this, the PCL + BG5% formulation remained biocompatible and significantly promoted angiogenesis compared to pristine PCL scaffolds. In sum, BG-laden scaffolds were successfully melt electrowritten, retaining the scaffolds' porous architecture, showing appropriate properties, including cell viability, adhesion, mineralized nodule deposition, biocompatibility, and angiogenesis, indicating that these materials are a promising alternative for enhancing bone tissue regeneration.
