Satellite cells, the stem cells of skeletal muscle, are responsible for muscle development and regeneration. Although low in abundance, satellite cells can be isolated from muscle but cannot be propagated successfully in culture in numbers needed for therapeutic use. We developed a method to generate cells with satellite cell characteristics from skeletal muscle organoid cultures.

Fluoxetine is a serotonin reuptake inhibitor antidepressant. Here, the authors demonstrate the that fluoxetine can trigger muscle regeneration in male mice by acting on muscle stem cells, vascularization, and inflammation, resulting in faster muscle healing.

Stress urinary incontinence (SUI), a frequently underdiagnosed condition that mainly affects women, lacks effective and long-term treatment options. MUVON Therapeutics has developed a tissue-engineered advanced therapy medicinal product for the treatment of SUI, based on autologous cells, which is being tested in a phase II clinical study — a challenging development effort.

Kaneshige et al. show that skeletal muscle-resident mesenchymal progenitors relay the mechanical signal of muscle overload to muscle stem cells to induce their proliferation.
