3D Microvascular Networks for Tissue Engineering

Описание: 3D Microvascular Networks are at the forefront of tissue engineering, combining microfluidics, biomimicry, and advanced 3D printing to replicate the complex vascular systems of natural tissues. These engineered systems create intricate channels resembling blood vessels, facilitating the delivery of nutrients, oxygen, and biochemical signals throughout tissue constructs. By using microfluidic channels comparable to capillaries, researchers can mimic the natural blood flow, ensuring the viability of thick tissues in regenerative medicine and organ transplantation.

A key method involves 3D printing and soft lithography to create sacrificial materials embedded in hydrogels. These materials are later removed to form hollow channels, which are then lined with endothelial cells, producing a living vascular network. Such networks not only maintain tissue viability by preventing hypoxia but also serve as platforms for disease modeling and drug testing. By simulating conditions like tumor angiogenesis or vascular responses to therapeutic agents, researchers can develop targeted therapies with greater effectiveness.

The integration of dynamic fluid flow is crucial to replicating natural blood circulation. These channels are designed to mimic pulsatile flow and shear stresses, promoting cell viability and tissue development. The use of biomimicry ensures that engineered tissues respond to physiological stimuli similarly to natural tissues, enhancing the accuracy of disease models and therapeutic testing.
