Extended Data Fig. 1 FACS gating strategy for other hSSC sources.

FACS gating plots for other three hSSC sources, including: fracture callus (28-year-old clavicle), femoral head (87-year-old) and iPSCs (human-monocyte-derived line, SCVI 113).

Extended Data Fig. 2 FACS gating strategy for SSCs of bone marrow reamings.

FACS gating plots for SSCs collected from human bone marrow reamings of 22-year-old femur (top) and 87-year-old hip (bottom).

Extended Data Fig. 3 Fluorescence Minus One (FMO) gating strategy.

FMO controls help to define the negative signal for the given antibody and allow for a more informed gating strategy. Cells were isolated from a 76-year-old male femoral head. Representative plots were generated on a FACS Aria II for each FMO (eg. anti-Tie2/CD31 in APC-Cy7, anti-CD235/CD45/DAPI in Pacific Blue, anti-PDPN in APC, anti-CD146 in PE-Cy7, anti-CD73 in FitC, and anti-CD164 in PE).
