NRP1 and neoplasm: In this context, it is noteworthy that PLAT and NRP1 play a well‐documented role in angiogenesis, in line with previous reports about a putative angiogenic function of IL6 in BCC.45, 46, 47 However, as we did not detect a decrease in CD31+ endothelial cells in Il6ra‐deficient mouse BCC (data not shown), it appears rather unlikely that HH‐IL6 signal integration drives BCC growth by supporting tumor angiogenesis.
