C57/BL6 CD45.1/2 congenic mouse strains were derived and maintained in our laboratory. Timed embryos from GFP transgenic HZ mice were used in the majority of the fetal bone (fb) transplantation studies. Sl/+ mice were purchased from Jackson laboratory.
Skeletal progenitors were isolated from fb (humerus, radius, tibia, femur, and pelvis, mandible without the condyle, and the individual frontal and parietal bones by collagenase digestion. They were next stained with antibodies against CD45, Tie2, αV integrin, CD105 and Thy1.1 for fractionation by FACS. Sorted and unsorted skeletal progenitors were then injected underneath the renal capsule of 8-12 week old anesthetized mice.
SLF and osterix specific shRNA knockdown constructs, active lentiviral stock, and non-silencing shRNA constructs were generated as previously described (ref 29 ; supplementary table 1). Fb cell suspensions were transduced for 48hrs with specific shRNA vectors or control, sorted for GFP expression and transplanted as described.
To assess HSC engraftment in ectopic niches, grafted regions were dissected from kidney and crushed by mortar and pestle. Dissociated cells were stained with fluorochrome-conjugated antibodies against CD45, lineage (CD3, CD4, CD5, CD8, B220, Gr-1, Mac-1 and Ter119), c-Kit, Sca-1, and CD150 for FACS analysis. Sorted KLS, CD150+ LT-HSC were transplanted into lethally irradiated (800 rads delivered in split dose) by intravenous injection for functional analysis. Peripheral blood was obtained from the tail vein at 4 and 23 weeks after LT-HSC transplantation to assess donor-derived contributions by FACS.
Histological analyses of endochondral ossification were performed on sections that were obtained from either fresh frozen, OCT-embedded or formaldehye-fixed, paraffin-embedded specimens. Representative sections were stained with either Hematoxylin-and-Eosin, Movat's modified pentachrome35, Safranin-O or Alizarin Red stains depending on the experiments.
RNA was extracted from sorted cells using Trizol (Invitrogen) or RNeasy RNA isolation kits (Qiagen) and was reverse-transcribed into cDNA with SuperscriptRT III (Invitrogen). SYBR Green Universal Master Mix and a GeneAmp 7000 or 7500 fast sequence detection system (Applied Biosystems) were used for real-time PCR with primers listed in supplementary table 2. Relative expression was calculated for each gene by the 2-ΔΔ CT method with β-actin for normalization.

Histological studies were performed on carotid arteries fixed with 10% buffered formalin under pressure (100 mmHg) in vivo for 2 h. Fixed specimens were embedded in paraffin following regular procedures. Five micrometre sections were stained with Sirius Red and Picrosirius Red (PSR) for collagen. PSR sections were imaged under cross-polarized light (darkfield) to observe collagen birefringence. Images were acquired on an Olympus BX/51 microscope using an Olympus DP70 digital camera (cellSens Dimension) under a × 40 magnification objective. The area fraction of collagen was based on total fibrillar collagen. A custom MATLAB script was used to extract layer-specific (media or adventitia) wall percentages as well as the proportions of thick (red) and thin (orange–yellow–green) birefringent collagen fibres.16 (link),17 (link)For integrin αv subunit immunostaining, rabbit polyclonal antibodies against integrin αv subunit, biotinylated goat anti-rabbit immunoglobulins, HRP-conjugated streptavidin, and 3,3′-diaminobenzidine (DAB) substrate (see Supplementary material online, Tables S7 and S8) were used. Composition of the arterial wall and the media cross-sectional area (MCSA) were determined using a Nikon NIS-Elements Basic Research microscope imaging software as described previously.18 (link)Immunofluorescence staining on 8 µm cryo-sections fixed with 4% paraformaldehyde or cooled acetone for 5 min was performed with specific antibodies as described previously.14 (link) Briefly, sections were incubated with primary antibodies at 4°C overnight after permeabilization with 0.2% Triton X100 for 10 min and blocking with 5% bovine serum albumin (BSA) for 1 h. After washing in PBS-Tween 20, sections were incubated with fluorescent-conjugated secondary antibodies. A complete list of antibodies is provided in Supplementary material online, Table S8. Image acquisition was on a Leica TCS SP5 confocal microscope (Leica, Wetzlar, Germany) with the same depth of field and with identical settings for laser, gain, and offset intensity.

Cell surface expression of various integrin receptor subunits or SLC3A2/CD98hc was measured by standard flow cytometry as previously described [32 (link)]. Briefly, the cells (1 × 106) were resuspended in the blocking buffer (DMEM supplemented with 2% BSA and 2% FCS) for 30 min on ice. The cells were then incubated with appropriate primary antibody: Chemicon (anti-integrin β1 MAB 1997 (clone MB1.2); anti-integrin α5 5H10-27 (clone MFR-5); anti-integrin α6 MAB 1378 (clone NKI-GoH3)); BD Pharmingen (anti-integrin β4 553745; anti-integrin αv 552,299 (clone RMV); anti-integrin β3 553343; anti-CD98hc H202-141); Invitrogen (anti-integrin β5 14-0497-82 (clone KN52); anti-integrin α2 14-5971-85 (clone DX5)) or matched isotype control diluted in labelling buffer (DMEM supplemented with 2% FCS) for 1 h on ice. Unbound antibodies were removed by washing twice with PBS, 2% FCS, and the cells were treated with an appropriate fluorescein isothiocyanate (FITC)-conjugated secondary antibody in a labelling buffer for 45 min on ice. The cells were washed again as above and stained with the viability dye 4′, 6′- diamidino-2-phenylindole (DAPI at 0.5 µg/mL) immediately prior to analysis on a BD FACS Canto II Flow Cytometer (BD Biosciences).

RIPA buffer (ThermoScientific, Rockford, IL, USA) and complete ULTRA Mini Tablets (Roche, Mannheim, Germany) was used to isolate protein from thrombus and IVC segments and cultured BMDMs or immortalized murine macrophages (RAW264.7 cells). For MMP9 and urokinase analysis, BMDMs and RAW264.7 cells were treated with either IL6 (20 ng/mL) or Brefeldin A (protein transport inhibitor; 500 ng/mL for 3 h).
