Utse–seam B-LINK components at the anchor cell B-LINK. (A) A schematic diagram indicating when imaging was conducted. (B) Florescence images (left) and corresponding differential interference contrast (DIC) image (right) of hemicentin::mNG, mNG::fibulin-1, α1-type IV Collagen::mRuby2, and perlecan::mNG underneath the anchor cell (yellow arrowhead) when a B-LINK connects the uterine and epidermal BMs. Hemicentin is enriched underneath the anchor cell (yellow arrowhead) compared to the neighboring BM (white arrowhead), while other matrix components are not enriched. White arrows indicate the anchor cell in DIC images. Scale bar, 5 µm.
