Summary: This study identified significant concentrations of progenitor cells and fibroblast-type cells in the subacromial bursal tissue of patients undergoing rotator cuff repair, with prominent amounts of fat and proteoglycans present in the matrix.

Summary: This study investigates the effect of exosomes derived from human urine-derived stem cells (USCs) and their subpopulations (CD133+USCs) on the regeneration of fibrocartilage tissue between tendon and bone during rotator cuff repair. The findings suggest that CD133+ USC-Exos hydrogel complex may be a promising therapeutic approach for rotator cuff healing.

Summary: The study found that patient demographics did not significantly affect the number of CFUs or NCC of CTPs derived from the SB, but tear size was negatively correlated with CFUs. This suggests that tear size, rather than patient demographics, may influence the viability of CTPs and should be considered in augmenting RC repairs with SB.

Summary: This study found that the use of UA-ADRCs injections for sPTRCT treatment is more effective than corticosteroid injections in the long run and carries no greater risks. Subjects in the UA-ADRCs group showed significantly higher ASES Total scores.

Summary: This study compared M-MSCs with adult-MSCs and found that M-MSCs have the potential to be used in next-generation therapies for rotator cuff tears (RCTs). They are able to regulate inflammation and promote tissue repair, leading to improved muscle recovery in RCTs.

Summary: This study found that exosomes secreted by young BMSCs can promote the healing of tendon-bone interface after rotator cuff tears. These exosomes can improve extracellular matrix remodeling, osteogenic differentiation, angiogenesis, and stemness of tendon-derived stem cells (TDSCs). The exosomes from young BMSCs have better effects compared to those from aged BMSCs.

Summary: Rotator cuff tendinopathy is a common disorder that causes a significant burden. Although stem cell therapy has shown promising results, there are many unresolved issues, such as determining the optimal source and dosage of stem cells, as well as standardizing patient types.

Summary: This study presents a novel therapeutic method that combines three-dimensional (3D) bioprinting and melt electrospinning writing techniques to regenerate the tendon-to-bone interface. The use of 3D-bioprinted pre-differentiated autologous adipose-derived mesenchymal stem cells (ADMSC) generated biomimetic multilayered scaffolds that recapitulated the compositional and cellular structures of the interface. In vivo studies demonstrated the superior histological score and improved collagen organization of the scaffold with spatially differentiated autologous ADMSCs.

Summary: The use of biologically enhanced demineralized bone matrix augmentation in the repair of complex rotator cuff tears shows promise in improving clinical outcomes. However, 50% of the patients in this study demonstrated failure of supraspinatus healing according to post-operative MRI.

Summary: Stem cell-related therapies play a significant role in rotator cuff repair, with their secretome having a significant impact on tendon-bone healing. Research indicates that by modulating macrophage polarization, the conditioned medium of stem cells can promote faster tendon-bone healing.

Summary: Severe rotator cable tears do not significantly impair rotator cuff function, while tears involving all rotator cuff tissue above the humeral head rotation center result in obvious functional impairment.

Summary: In a cohort of patients with shoulder pain, older age, involvement of the dominant shoulder, and a higher body mass index were found to be independently associated with rotator cuff tears. Further research is needed to understand the mechanisms behind these associations.

Summary: Human MenSCs encapsulated in autologous platelet-rich gel (APG) promote the healing of chronic rotator cuff tears by enhancing the formation of new bone tissue and regenerating mature fibrocartilage. This treatment also improves the mechanical properties of the repaired cuff.
