Despite its potential, bioprinting faces several challenges:
Vascularization: Creating blood vessels within printed tissues to ensure proper nutrient and oxygen supply. Material Limitations: Finding suitable biomaterials that can support cell growth and function while being printable. Cell Viability: Ensuring that cells remain alive and functional throughout the printing process and subsequent maturation. Regulatory and Ethical Issues: Addressing the ethical concerns and regulatory hurdles associated with creating and using bio-printed tissues and organs.
