Abstract

This study aims to develop a method using a three-dimensional hydrogel that mimics glycosaminoglycans to accelerate the development of cartilage cells. The hydrogel contains a specific glycosaminoglycan-like peptide sequence with the potential to enhance the effectiveness of chondrogenic differentiation and provide a more efficient approach. In the study, ATDC5 cells were cultured within a synthetic scaffold incorporating peptide amphiphile (PA) nanofibers designed to emulate the structure of glycosaminoglycans in a three-dimensional format for tissue engineering applications. Cellular characterizations were conducted to induce chondrogenic differentiation. ATDC5 cells cultured on GAG-mimicking peptide nanofibers expressed cartilage-specific extracellular matrix components statistically significantly over a 14-day period compared to cells cultured on TCP without insulin induction. Amphiphilic peptide nanofibers offer a valuable approach to replicate glycosaminoglycan properties and support chondrogenic differentiation in ATDC5 cells without the need for growth factors or external stimuli. This approach holds substantial potential for clinical applications in cartilage tissue engineering.
