What are the current limitations and challenges faced in the field of bio-printing technology for diabetic wound healing?
Current limitations and challenges in bio-printing technology for diabetic wound healing include the inaccurate replication of host tissue properties, lengthy in-vitro cell culture periods, complex deposition technologies, and lack of credible point of care delivery protocols . Additionally, the prolonged inflammation in diabetic wounds poses a challenge, necessitating customized dressing materials that can effectively treat wounds of varying shapes and depths . Traditional treatment methods for skin repair are still inadequate in terms of repair time, costs, and results, highlighting the need for advancements in bioprinting technology . Bio-based materials have shown promise in enhancing wound healing by stimulating cellular and molecular processes, inhibiting pathogen growth, and promoting angiogenesis . Despite advances in 3D bioprinting, there remains a gap between existing tissue-engineered skin and natural skin, emphasizing the need for more comprehensive in vitro skin models .
