A polymeric scaffold is a porous, three-dimensional, biodegradable polymer structure designed to provide a temporary physical and chemical substrate on which cells can attach, proliferate, and organize into functional tissue [1]. The scaffold acts as an artificial extracellular matrix that defines the space to be regenerated while guiding cell migration, nutrient transport, and mechanical loading, and it is intended to degrade in a controlled manner as the neo-tissue matures [2]. Essential structural attributes include high interconnected porosity, a well-defined pore-size distribution, an appropriate surface chemistry for cell adhesion, and mechanical properties matched to the target tissue, because the pore network must simultaneously permit cell ingrowth, vascularization, and diffusion of nutrients and waste while supporting loads [3]. Polymeric scaffolds are typically fabricated from natural or synthetic polymers and their architecture is generated through techniques that control fiber or pore geometry; their defining feature is that they serve as a transient template whose role is to deliver cells and signaling cues rather than to act as a permanent implant [2]. They are distinguished from non-porous polymer implants by their open, interconnected microstructure, which is the basis for their tissue-engineering function [1].
