Harnessing Human Placental Membrane-Derived Bioinks: Characterization and Applications in Bioprinting and Vasculogenesis
ADVANCED HEALTHCARE MATERIALS(2024)
摘要
Bioprinting applications in the clinical field generate great interest, but developing suitable biomaterial inks for medical settings is a challenge. Placental tissues offer a promising solution due to their abundance, stability, and status as medical waste. They contain basement membrane components, have a clinical history, and support angiogenesis. This study formulates bioinks from two placental tissues, amnion (AM) and chorion (CHO), and compares their unique extracellular matrix (ECM) and growth factor compositions. Rheological properties of the bioinks are evaluated for bioprinting and maturation of human endothelial cells. Both AM and Cho-derived bioinks sustained human endothelial cell viability, proliferation, and maturation, promoting optimal vasculogenesis. These bioinks derived from human sources have significant potential for tissue engineering applications, particularly in supporting vasculogenesis. This research contributes to the advancement of tissue engineering and regenerative medicine, bringing everyone closer to clinically viable bioprinting solutions using placental tissues as valuable biomaterials. Bioprinting for clinical applications holds great promise but requires appropriate biomaterial inks. Placental tissues, often discarded as medical waste, offer a compelling solution due to their abundance, stability, established clinical history, and angiogenic properties. This study develops bioinks from amnion and chorion, investigating their extracellular matrix and growth factor compositions. These bioinks, fostering human endothelial cell viability and vasculogenesis, hold significant potential for tissue engineering, advancing the feasibility of clinically viable bioprinting using valuable placental biomaterials.image
