Systemic sclerosis (SSc) skin tissue sections stained with antibodies against CUX1 and α-smooth muscle actin (SMA). The figure shows epidermis that were stained by CUX1 and α-SMA antibodies. The granular and prickle cells in the epidermis were positive for CUX1 and α-SMA. CUX1 localised within α-SMA-positive cells. Normal skin sections were used as negative control for CUX1 and α-SMA.
