Channels in a porous scaffold: a new player for vascularization
In this Special Report from Regenerative Medicine, the authors review the function of channels in porous scaffolds and the approaches to produce those channels. Keywords: 3D printing - microchannels - regenerative medicine - scaffold - tissue engineering - vascularization Vascularization is essential for tissue regeneration. Despite extensive efforts in the past decades, sufficient and rapid vascularization remains a major challenge in tissue engineering. Many studies have shown that the addition of channels in a porous scaffold can provide the ability to promote cell growth and rapid vascularization, thus leading to better outcomes in new tissue formation. Large size scaffolds lack...
