This research was undertaken after approval from the Leeds East National Research Ethic Committee and informed written consent was obtained from all patients and healthy donors enrolled in the study. Femoral heads were obtained from patients undergoing total hip arthroplasty for primary OA (n = 26). Healthy iliac crest (IC) bone (n = 11) and femoral heads from fragility neck of femur fracture (NFF) patients (n = 3) were used as controls. Iliac crest biopsies were collected from patients undergoing orthopaedic surgery for metal removal following previous fracture, who were otherwise healthy. All bone samples were collected and processed on the day of the surgery and are detailed in the Supplementary Table S1, available at Rheumatology online. Bone-resident MSCs were extracted by 4-h enzymatic digestion [8 (link)] and cell sorting [12 (link), 13 (link)]. Following digestion, the bone fragments were rigorously washed four times in large volumes of PBS using a method modified from Pathak et al. [14 (link)] to remove all residual cellular material from the bone surface. Osteocyte-enriched bone fragments were next homogenized in lysis buffer (guanidine isothiocyanate solution with 0.4% sodium citrate, 1% N-lauryl sarcosine and 0.5% β-mercaptoethanol) and RNA was precipitated with isopropanol and DNase treated (Invitrogen, Fisher Scientific, Leicestershire, UK). Total RNA from FACS-purified CD45-CD271+ MSCs and control CD45+CD271- haematopoietic-lineage cells [12 (link)] was extracted using the Single-Cell RNA Extraction kit (Norgen Biotek, Geneflow, Lichfield, UK) and on-column DNase (Applied Biosystems, Foster City, California, USA) treated. cDNA was synthesized using the High-Capacity cDNA Reverse Transcription Kit (Applied Biosystems, Foster City, California, USA). qPCR was performed on a QuantStudio7Flex Real-Time PCR System (Applied Biosystems) and gene expression levels normalized relative to housekeeping gene HPRT1. The TaqMan probes for the genes of interest are detailed in Supplementary Table S2, available at Rheumatology online, all from Thermo Fisher. To evaluate multipotentiality, FACS-purified CD45-CD271+ were culture-expanded and differentiated towards osteogenic, adipogenic and chondrogenic lineages as described previously [8 (link), 12 (link)].

Breast epithelial cells were collected by trypsinization, stained using antibodies CD49f-APC (FAB13501A), AXL-APC (FAB154A) (R&D Systems), PROCR (CD201)-PE (130–105-256), EpCAM-PE (130–091-253), EpCAM-APC (130–091-254), EpCAM- VioBlue (130–097-324) (Miltenyi Biotech Inc.), CD271-APC (345108) (Biolegend), CD44-APC (559942), CD24-PE (555428) (BD Pharmingen), Pan-Cytokeratin-FITC (F3418) (Sigma Aldrich) and ALDEFLUOR (01700) (STEMCELL Technologies), and were acquired using a BD LSR II flow cytometer. Data were analyzed using CellQuest or FlowJo software. Forward and side scatter were used to ensure that only live cells were considered in the analysis. Gating was done using appropriate FITC (555573), PE (555749), APC (555576) (BD Pharmingen) and VioBlue (130–094-670) (Miltenyi Biotech) isotype control antibodies and only a representative isotype control for two fluorescent markers are shown.
For imaging flow cytometry, 500,000–1,000,000 cells per sample were stained with the following conjugated antibodies: 1:100 mouse anti-Vimentin Clone V9-Cy3, (C-9080, Sigma-Aldrich), and 1:20 mouse anti-CD324/E-Cadherin Clone 67A4-APC, (A15717, Molecular Probes). The nucleus was stained with 1:5000 Hoechst 33342 (H-3570, Molecular Probes). Cells were fixed and permeabilized using BD Cytofix/Cytoperm solution (51–2090KZ, BD Bioscience) for 20 minutes at 4°C. Blocking was done with 5% goat serum in 1X BD Perm/Wash solution (51–2091KZ, BD Bioscience) for 15 minutes at 4°C. Single color control samples and cocktail sample with all the antibodies were incubated for 30 minutes at 4°C in dark. Cells were washed twice for 5 minutes between each step with 1x BD Perm/Wash solution. The last step of washing was done twice with 1x PBS to eliminate the detergent from the cell suspension. Cells were transferred to the UltraClear boil proof microcentrifuge tubes (Inc-607-GMT, Dot Scientific). The stained cells were stored in 1% formalin in dark at 4°C. 5000 images were analyzed using ImageStream Data Exploration and Analysis Software (IDEAS). In-focus cells were evaluated after gating on live single cells based on an aspect ratio near 1 and a low area of the bright field.

TCR constructs were subcloned into a pCCLc-MND-based lentiviral vector in the format TCRα-F2A-TCRβ-P2A-Myc271. Myc271 is a novel chimeric transduction marker comprising the transmembrane and truncated extracellular domains of CD271(LNGFR) fused to an extracellular cMyc epitope tag. Lentiviral vectors were prepared from 293T producer cells. One day prior to transfection, 1 x 106 293T cells/well were plated on 6-well plates. In 100 μL PBS, added 1 μg TCR lentivector, 1 μg pCMV-R8.2 (gag-pol helper plasmid), 0.2 μg pCAGGS-VSVG (pseudotyping helper plasmid), and 6.6 μL polyethyleneimine transfection reagent (Sigma) and incubated for 10 min. Fresh 2 mL media was replaced on plated 293T, and then transfection mix was added to cells. 48 hr following transfection, Jurkat T cells (10 (Johnson et al., 2009 (link)) cells/well in 250 μLC10) were added on a 24-well plate and 250 μL filtered (0.45 μm) viral supernatant was added to cells to initiate transduction. After 60–72 hr of transduction, Jurkats were assayed for TCR surface expression and function. To test for surface expression, cells were rinsed and stained with fluorescent antibodies and pMHC multimers in FACS buffer, and analyzed by flow cytometry. Dead cells were excluded from analysis using 7-AAD. To test for function, unselected Jurkat T cells were co-incubated in a 96-well plate at a 1:1 ratio with K562 cells stably expressing control or cognate peptide-MHC single chain trimers. After 48 hr of coincubation, the supernatant was tested for secreted interleukin-2 with a commercial ELISA kit according to the manufacturer’s protocol (BD, Franklin Lakes, NJ).

A CFU‐F assay was performed as described previously 11, with a minor modification using methylene blue, before scoring was performed in a blinded manner. MSC expansion was used to measure MSC proliferation rates and to produce a sufficient number of cells for trilineage differentiation assays and gene expression analysis. MSCs were expanded in StemMACS MSC Expansion Media after preenrichment using CD271 MACSelect MicroBeads (both from Miltenyi Biotec), and culture population doublings were calculated as previously described 20. MSCs from the bone of healthy controls and patients with OP were expanded similarly following their enzymatic release from bone 11.

Each sample was transferred to a collection tube and resuspended in PBS/1% BSA/5mM EDTA. Fluorescently tagged antibodies were added at concentrations presented in Table 3 and incubated for 30 min on ice. Labeled cells were washed three times with PBS to remove unbound antibody and resuspended in flow buffer (PBS with 2% BSA, 1 mM EDTA, and 1 μg/mL DAPI). Cells were sorted on a BD FacsAria III. LEps were defined as CD133+ /CD271− cells, and MEps were defined as CD133−/CD271+ cells, with DAPI + cells discarded. Compared to cells from standard 2-D cultures, postconfluent cells exhibit marked autofluorescence.
