Table 2. Cellular composition of patient biopsies at two different time points after surgery.

Semiquantitative findings of CD146⁺NG2⁺ PVSCs and desmin⁺ muscle cells in patient biopsies at 5 to 8 weeks and 24 to 32 weeks after surgery. Angiogenesis was evaluated by the presence of vWF⁺ vasculature structures. CD146⁺NG2⁺ PVSCs were identified independent of CD31⁺ vessels. Desmin⁺ cells identified the presence of skeletal muscle cells. −, absent; +, few isolated cells; ++, moderate number of cells or small clusters; +++, large numbers of cells or large cell clusters.
