Human skin equivalents (HSE) are three-dimensional (3D) living models of human skin that replicate the biological properties and interactions within skin. They provide ideal testbeds for many applications such as wound healing assessment, drug assessment, etc. and are now seeing application with patients in surgical theatres. For these lab-cultured tissues to be further applicable as mainstream procedures, their mechanical and optical properties must be comparable to in vivo skin. In our lab, we are interested in studying the nexus of tissue engineering and biomedical optics to observe and compare lab synthesis to the real-world analogy. In collaboration with Dr Junaid (Aston University), we focus on understanding the propagation of light through skin from both a simulation and experimental perspective. If you’re interested in more technical details, analysis and results from a recent study can be found in Kallepalli et al. 2020.
