Mesenchymal Stem Cell-Derived Extracellular Matrix for Musculoskeletal Tissue Regeneration
Mesenchymal stem cell-derived extracellular matrix (mECM) is increasingly recognized in tissue regeneration due to its high biocompatibility, controllability, and customizability. In musculoskeletal diseases, mECM provides a 3D scaffold mimicking the natural cellular environment and contains bioactive components regulating cell behavior and fate to promote tissue regeneration and repair. This review summarizes the preparation methods and composition of mECM, its effects on regulating cell behavior, and its applications in bone, cartilage, muscle, nerve, and blood vessel repair.

Stem Cell Therapy for Spinal Cord Injury: Lessons from Japan`s Experiment in Regulatory Deregulation
Stem cell-based therapies for spinal cord injury (SCI) have generated substantial global interest; however, no regenerative treatment has yet demonstrated sufficient efficacy to achieve full regulatory approval in major jurisdictions. In Japan, an expedited regulatory framework enabled the conditional approval of Stemirac, an autologous mesenchymal stem cell therapy for SCI, based on limited and uncontrolled clinical evidence. This Perspective examines the scientific, methodological, and ethical implications of that decision. Focusing on trial design, outcome assessment, extensive public and media attention during the confirmatory trial period, and downstream societal consequences, we explore how premature commercialization under public reimbursement may compromise scientific rigor and erode public trust.

Stem Cell Therapy for Traumatic Brain Injury: Current Advances, Clinical Challenges, and Future Directions
The severity of traumatic brain injury (TBI) and its poor prognosis underscore the urgent need for more effective neuroprotective and neuroregenerative strategies. However, the pathological heterogeneity of TBI continues to hinder clinical therapeutic progress. Preclinical studies have shown that neural stem cells, through their regenerative and secretory properties, can suppress neuroinflammation and promote angiogenesis, synaptic regeneration, and neural circuit remodeling. On one hand, stem cell transplantation has entered clinical trials and demonstrates neuroprotective effects by promoting regeneration at the injury site. However, reliable evidence supporting its clinical benefits in severe TBI remains limited.

From Scalpels to Stem Cells: How Regenerative Medicine Is Changing Spine Surgery
For much of modern history, orthopedic surgery has relied on precision, hardware, and long recoveries. The rhythm was familiar: a problem in the spine or joint would lead to imaging, diagnosis, and ultimately surgery. But in the last decade, a quiet revolution has begun. Instead of opening the body to fix what is broken, physicians like Dr. Michael Gerling are learning how to help the body repair itself.

Stem Cell Pain Sponge Soaks up Osteoarthritis Joint Pain and Protects Cartilage
SereNeuro Therapeutics revealed promising results for SN101, a first-in-class iPSC-derived therapy designed to treat chronic osteoarthritis pain while protecting joint tissue. Instead of blocking pain pathways, SN101 uses lab-grown nociceptors that act like sponges, soaking up inflammatory pain factors without sending pain signals. These cells also release regenerative molecules, offering disease-modifying potential that stands apart from traditional corticosteroids and single-target drugs like Nav1.8 inhibitors.

Initial Safety Outcomes of Adipose-Derived Mesenchymal Stem Cell for Rotator Cuff Tear: A 3-Year Pilot Trial
Injection of autologous MSCs derived from adipose tissue is safe in treating total rotator cuff tear. These findings support the initiation of larger-scale trials to further investigate the therapeutic potential and efficacy of MSCs in tendon regeneration.

Regenerative Stem Cell Therapy: Good Alternative To Joint Replacement Surgery?
Stem cell therapy offers a minimally invasive alternative to joint replacement surgery, with recovery times of just one to two weeks compared to months for major surgery. Clinical studies show varying success rates, with 60-80% of patients in some trials experiencing significant pain relief and improved mobility, though results depend on condition severity and treatment type.
