Pe conjugated mouse anti human cd105

For flow cytometry analysis, MSCs or Pio-MSCs were trypsinized and washed twice prior to resuspension in PBS containing 2% FBS and 1 mM EDTA. Cells were adjusted to 1 × 10⁶ in 100 µL of cell suspension. For cell surface labeling, cell suspensions were incubated at 4 °C for 30 min with 5 µL of antibodies (dilution, 1:20) against MSC-specific surface markers. Phycoerythrin (PE)-conjugated mouse anti-human CD73, fluorescein isothiocyanate (FITC)-conjugated mouse anti-human CD90, and PE-conjugated mouse anti-human CD105 antibodies were supplied by BD Biosciences (San Jose, CA, USA). FITC-conjugated mouse anti-human CD34 was supplied by BD PharMingenTM (San Jose, CA, USA). Cell surface marker analysis was performed using a BD FACSCanto™ II Flow Cytometer and FACSDIVA software version 6.1.3 (BD Biosciences, San Jose, CA, USA).
