Figure 2: Light microscopy image of the human keratinocytes in ESWT exposed and control keratinocytes. ESWT treatment causes morphological changes in human keratinocytes in vitro. Acontrol group, untreated human keratinocytes are similar in shape and size. ESWT group was heterogeneous in size and shape (3C). Large oval cells were present in the area of cell detachment caused by ESWT (3B). Magnifications 100X.
