Vascularisation in 3D bioprinted models: emerging solutions for engineering functional tissues and tumour models. (PubMed, Biofabrication)
Mechanical and biochemical cues, including controlled flow, shear stress, and angiogenic factor gradients, are presented as key regulators of vascular maturation and perfusion stability. Validation metrics such as perfusion stability, oxygenation profiles, barrier integrity, and drug transport are emphasised as essential for assessing physiological relevance.
Emerging technologies, including smart stimuli-responsive bioinks, 4D bioprinting enabling temporal tissue transformation, and AI-assisted adaptive volumetric fabrication, offer promising solutions for context-aware and dynamically regulated vascular systems.
Together, this comparative framework guides strategy selection for either long-term regenerative perfusion or the pathophysiological complexity of tumour vascularisation, and provides practical design principles for translating vascularised tissue models toward clinical application and industrial-scale biofabrication.
