KLK6 mRNA expression in PDAC tissues. (a) Representative images of dual in situ hybridisation of KLK6 (green) and αSMA (red) in normal pancreas and PDAC tissues. (b) KLK6 was expressed by stromal cells at very low levels and did not correlate with (non)invasive tumour areas and tumour stage. (c) Representative images of dual in situ hybridisation of KLK6 (green) and CD68 (red) in normal pancreas and PDAC tissues. (d) KLK6 was expressed by CD68+ cells at very low levels and correlated with invasive tumour areas compared to the noninvasive counterparts. Asterisks indicate statistical significance (** p ≤ 0.01; ns, not significant).
