Abstract

In recent years the need for in vitro skin models as a replacement for animal studies has resulted in significant progress in the development of skin-on-a-chip models. These devices allow the fine control of the microenvironment of the model and the incorporation of chemical and physical stimuli. In this study, we describe the development of an easy and low-budget open-top dynamic microfluidic device for skin-on-a-chip experiments using polydimethylsiloxane and a porous polyethylene terephthalate membrane. The chip allows the incorporation of compressive stimuli during the cultivation period by the use of syringe pumps. Proof-of-concept results show the successful differentiation of the cells and establishment of the skin structure in the chip. The microfluidic skin-on-a-chip models presented in this study can serve as a platform for future drug and feasibility studies.
