*Species-specific antibody (all others are antihuman antibodies). NC: no cross-reactivity; CND: cross-reactivity not determined. Symbols indicate marker expression levels: −: no expression; +−: <5% expression; +: 5−50% expression, ++: 50−100% expression. **Markers specific for MSCs and MPCs are included due to confusion in terminology.
