Endothelial Cells in the Perivascular Niche Remodel to Surround a Single HSPC

(A) Four frames from time-lapse Movie S2 40–42 hpf (hr post fertilization:min). Upper row is a merge of Runx:GFP+ HSPC (green, middle row) and kdrl:RFP ECs (red, lower row). A group of surrounding ECs (broken circle) remodel around a single HSPC soon after its arrival.

(B) Higher magnification (60×) live image of single Runx:GFP+ HSPC surrounded by kdrl:mCherry ECs at 78 hpf (orthogonal views).

(C) 3D rendered projection of scanning confocal image from fixed 80 hpf embryo. (i) merge, (ii) kdrl:mCherry ECs, (iii) Runx:GFP+ HSPCs, (iv) DRAQ5 nuclei, and (v) kdrl:mCherry projection with 3D modeled green HSPCs and five blue surrounding EC nuclei (arrowhead indicates HSPC in EC surround).

All views: dorsal up, ventral down. Scale bars, 10 µm. See also Figure S3.
