Harnessing Bioprinting Technologies for Diabetic Wound Regeneration

A chronic metabolic condition, diabetes mellitus (DM), is becoming more common all over the globe. Diabetic complications include diabetic foot ulcers (DFUs). Between fifteen and twenty-five percent of people with diabetes will experience DFU at some point in their lives. Prolonged hospital stays and amputations are common outcomes of DFUs due to the absence of targeted therapy and appropriate wound dressings. Specialized DFU wound care is expected to be in high demand due to the anticipated increase in the prevalence of DM. Therefore, there is a strong need to enhance and create more effective wound dressings and therapies that are unique to DFU. Bioengineered tissues, individualised prostheses, and implants are just a few examples of how 3D bioprinting has revolutionised healthcare in the past decade. This review delves into the difficulties of wound management and explores how 3D bioprinting could improve existing treatment approaches and biomanufacturing composite 3D human skin substitutes as an alternative to skin grafting. To alleviate the healthcare burden caused by the rising incidence of DM, it will be crucial to co-develop 3D bioprinting technologies with new therapeutic techniques to address the unique pathophysiological problems of DFU in the future.
