We noted that MMP14 was also expressed by CD169– cells throughout the paracortical region, and that FcgR1 and FcgR3A were expressed by SSMs only in specific locations and mainly from SSMs with direct access to the subcapsular sinus, which led us to speculate that those SSMs may be closer to tumor-draining afferent lymphatics. Here, SIGLEC1 is linked to neoplasm.
