Decellularized apple hypanthium as a plant-based biomaterial for cartilage regeneration in vitro: a comparative study of progenitor cell types and environmental conditions
Year: 2025
Type: article
Abstract: BACKGROUND: Decellularized plant tissues have been shown to enhance the integration and proliferation of human cells, demonstrating biocompatibility. These tissues are now being considered as valuable biomaterials for tissue engineering due to their diverse architectures and favorable cytocompatibility. In this study, we assessed decellularized apple hypanthium as a potential biomaterial for generating cartilage-like structures, utilizing four different progenitor cell types and varying environmental conditions in vitro. RESULTS: Cell viability assays indicated integration and cell proliferation. Histological staining and gene expression analyses confirmed the synthesis and deposition of a cartilaginous extracellular matrix. Notably, hypoxia had varying effects on chondrogenesis based on the cell type. Among the progenitor cells evaluated, those derived from auricular perichondrium were particularly promising, as they differentiated into chondrocytes without requiring a low-oxygen environment. Additionally, our findings demonstrated that apple-derived biomaterials outperformed microencapsulation in alginate beads in promoting chondrogenesis. CONCLUSION: These results highlight the potential of plant-based biomaterials for the development of implantable devices for cartilage regeneration and suggest broader applications in tissue engineering and future clinical endeavors.
