Using 4D printing to enable vascularization, bone tissue regeneration, spinal fusion

There has been an increase in the number of people over 65 who have needed spinal fusion surgery, and many have focused on trying to create a biomimetic scaffold that induces vascularization. Researchers present a solution to address the challenge: They designed a microchannel scaffold made of a collagen and hydroxyapitite combination, with each strut consisting of micrometer-scaled microchannels. The microchannels have induced growth of blood vessels in a mouse model.
