The detailed information of cell subpopulation in various research

Subpopulation	Outcome	Material sources	Donor age	Reference
CD9+CD90+CD166+	The potential for osteochondral differentiation	Patients with end-stage OA who underwent total knee joint replacement	55–82	Fickert et al. [49]
CD271+CD90+	The potential for chondrogenic differentiation	Patients with total knee arthroplasty surgery	N/A	Ogata et al. [51]
CD73+CD90−/CD73+CD90+	CD73+CD90− cells can form cartilage only under the stimulation of TGFβ-1; the CD73+CD90+ MSCs subgroup needs to be stimulated by BMP2 and TGFβ-1	Patients with advanced clinical OA who underwent total knee replacement	50–80	Sivasubramaniyan et al. [30]
SM-MSCs in surface, interstitial and perivascular area	Higher proliferation and chondrogenic potential of MSCs in perivascular area	The knees of patients with osteoarthritis during total knee arthroplasty	59–85	Mizuno et al. [14]
SM-MSCs in the paralabral synovium and the cotyloid fossa synovium	MSCs from the cotyloid fossa synovium have higher proliferation and differentiation potential than do those from the paralabral synovium	Patients with femoroacetabular impingement syndrome but excluded osteoarthritis and inflammatory diseases	19–64	Murata et al. [52]
SM-MSCs in the cotyloid fossa area from the knee and hip	Adipogenesis and osteogenesis potentials of MSCs from the knees are superior to those of MSCs from the hips in the same donor	Patients underwent knee and hip arthroscopic surgeries	25–64	Hatakeyama et al. [54]
