Recent clinical trials on ADSC-based therapies for musculoskeletal regeneration
Application | Participants | Methods | Follow-up time | Results | References |
---|---|---|---|---|---|
Bone regeneration | 13 patients with craniomaxillofacial hard-tissue defects | Autologous ADSCs were seeded onto either bioactive glass or β-tricalcium phosphate scaffolds and transplanted into the bone defect area | 12–52 months | In 10 of 13 cases, the construct was successfully integrated into the surrounding skeleton | Sándor et al. [101] |
5 cranial defect patients | Patients received cranioplasties using autologous ADSCs, beta-tricalcium phosphate granules, and supporting meshes | 6 years | Long-term clinical results were not satisfactory, partially owing to graft resorption, tumor recurrence, or late infection | Thesleff et al. [103] | |
Cartilage regeneration | 12 patients with knee osteoarthritis | Autologous ADSCs were intra-articularly administered | 6 months | ADSC injection provided significant functional improvement and pain relief | Lee et al. [127] |
53 patients with symptomatic knee osteoarthritis | Autologous adipose-derived mesenchymal progenitor cells (haMPCs) expanded in vitro were intra-articularly injected | 12 months | Significant improvements in joint function, pain, quality of life, and cartilage regeneration with good tolerance | Lu et al. [128] | |
30 patients with symptomatic knee osteoarthritis | Intra-articular ADSC therapy | 12 months | Autologous ADSC therapy is safe and effective and can prevent disease progression | Freitag et al. [129] | |
18 patients with knee osteoarthritis | Autologous ADSCs were intra-articularly injected | 96 weeks | Autologous ADSCs improved the pain, function, and cartilage volume of the knee joint | Song et al. [131] | |
Tendon regeneration | 70 patients with full-thickness rotator cuff tear | 35 patients underwent arthroscopic rotator cuff repair with autologous ADSC injections, whereas 35 patients underwent only repair surgery | At least 12 months | ADSC injection during rotator cuff repair significantly decreased the retear rate; furthermore, the function of the repaired tissue was similarly ameliorated in both groups | Kim et al. [158] |
18 patients with partial-thickness rotator cuff tear | Intratendinous injection of autologous ADSCs | 2 years | Autologous ADSC injection improved shoulder function, relieved pain, and exhibited continued safety and efficacy | Jo et al. [160] | |
11 patients with partial-thickness rotator cuff tears | Autologous adipose-derived regenerative cells were injected into the shoulder with a single injection | 12 months | Autologous adipose-derived regenerative cell injection improved shoulder function without adverse effects | Hurd et al. [161] | |
44 patients with degenerative posterosuperior rotator cuff tear | 22 patients underwent arthroscopic rotator cuff repair augmentation with autologous microfragmented lipoaspirate tissue, whereas 22 patients underwent only repair surgery | 24 months | Injection of autologous microfragmented adipose tissue effectively promoted functional rotator cuff repair | Randelli et al. [162] |
