Current In Vitro Biofilm-Infected Chronic Wound Models for Developing New Treatment Possibilities

Significance:The prevalence of chronic wounds is increasing worldwide. The most recent estimates suggest that up to 2% of the population in the industrialized countries is affected. Recent Advances:During the past few decades, bacterial biofilms have been elucidated as one of the primary reasons why chronic wounds fail to heal. Critical Issues:There is a lack of direct causation and evidence of the role that biofilms play in persistent wounds, which complicates research on new treatment options, since it is still unknown which factors dominate. For this reason, several differentin vitrowound models that mimic the biofilm infections observed in chronic wounds and other chronic infections have been created. These different models are, among other purposes, used to test a variety of wound care products. However, chronic wounds are highly complex, and several different factors must be taken into consideration along with the infection, including physiochemical and human-supplemented factors. Furthermore, the limitations of usingin vitromodels, such as the lack of a responsive immune system should always be given due consideration. Future Directions:Present understandings of all the elements and interactions that take place within chronic wounds are incomplete. As our insight ofin vivochronic wounds continues to expand, so too must thein vitromodels used to mimic these infections evolve and adapt to new knowledge.

Automated summary

The prevalence of chronic wounds is increasing globally, with bacterial biofilms identified as a key factor hindering healing. Lack of direct causation and evidence regarding the role of biofilms complicates research on new treatment options, necessitating the use of various in vitro wound models for testing.
