“…It is possible to divide bioprinting technologies into 3 categories through their modeling concept and the material that the print is made from. They are droplet-based bioprinting (DBB), extrusion-based bioprinting (EBB), and photopolymerization-based bioprinting (PBB) [11][12][13].…”

Introduction: Annually, 50% of medical expenses worldwide stem from damage to the body's tissues and organs. Large skin defects can be caused by tumor excision, venous ulcers, diabetic foot ulcers, and burns. The 3D bioprinting of skin has an advantage compared to other technologies for skin substitutes, the capacity for directional and spatial handling at the cellular level with variable density. Objective: It was to identify the most efficient 3D bioprinting strategies and their application in studies in vivo and in vitro animal models, to demonstrate state of art in skin regeneration, and to direct new clinical research with translational studies. Methods: The rules of the Systematic Review-PRISMA Platform were followed. The research was carried out from November 2022 to February 2023 and developed based on Scopus, PubMed, Science Direct, Scielo, and Google Scholar. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results: A total of 237 articles were found and 97 articles were evaluated in full, and 16 were included and described in the present study. According to the GRADE instrument, most studies (X2 =90.5%>50%) followed a controlled clinical study model and had a good methodological design. the biases did not compromise the scientific basis of the studies. Conclusion: Most organotypic skin models have an epidermal layer of keratinocytes and a dermal layer of fibroblasts embedded in an extracellular matrix-based biomaterial. Furthermore, skin comprising epidermis, dermis, and hypodermis stratified with blood vessels, nerves, muscles, and cutaneous appendages can be fabricated. These findings provided evidence for further advances in translational studies in humans.
