Intrathecal delivery of adipose-derived mesenchymal stem cells in traumatic spinal cord injury: Phase I trial
In the CELLTOP Phase I trial, stem cells were harvested from patients with spinal cord injury and injected into their central nervous system after processing. The procedure was safe, with no reported serious adverse events during the 2-year follow-up period.

Autologous cell transplantation for treatment of colorectal aganglionosis in mice
Neurointestinal diseases cause significant morbidity and effective treatments are lacking. Here, authors perform autologous cell transplantation of enteric neural stem cells in a mouse model of colonic aganglionosis and report restoration of colonic contractile activity.

A biodegradable hybrid inorganic nanoscaffold for advanced stem cell therapy
The promise of stem cell therapy for treating central nervous system disease is limited by low stem cell transplantation survival rates and poorly controlled cell fate. Here, the authors develop a biodegradable nanoscaffold for spinal cord injury that enhances transplantation and differentiation of neural stem cells and delivers drugs.

Whole-genome mutational burden analysis of three pluripotency induction methods
It is feared that reprogramming may introduce DNA mutations. Here Bhutani et al. take three different reprogramming methods and using comparative whole genome analyses do identify nucleotide variations that are different in reprogrammed cells from the original fibroblasts, but none convey oncogenic potential.

Therapeutically engineered induced neural stem cells are tumour-homing and inhibit progression of glioblastoma
Neural stem cells have a tropism for glioblastoma. Here the authors employ fibroblasts directly reprogrammed into induced neural stem cells and loaded with cytotoxic molecules to migrate to xenotransplanted brain tumours in mice, achieving tumour shrinkage and prolonged survival.

Autonomous beating rate adaptation in human stem cell-derived cardiomyocytes
The use of stem cell-derived cardiomyocytes for heart repair is hampered by their immature structural and contractile properties that may cause arrhythmia. Here, Eng et al.show that electrical conditioning of human cardiomyocytes in 3D culture can enhance connectivity and provide resistance to arrhythmia.

Sepsis induces long-term metabolic and mitochondrial muscle stem cell dysfunction amenable by mesenchymal stem cell therapy
Sepsis patients often develop muscle atrophy that can last for years. Here the authors show in a mouse model that sepsis causes long-term impairment of the satellite cells, affecting mitochondrial function and energy metabolism, and that injection of mesenchymal stem cells restores satellite cell metabolism and muscle regeneration.

Tolerance induction to human stem cell transplants with extension to their differentiated progeny
Immunosuppression has been shown to induce tolerance to transplanted stem cells, but differentiation of these cells may trigger immune rejection later on. Here, Lui et al. show that a short-term immunosuppression regimen confers long-term tolerance to stem cells and their differentiated progeny.

An ex vivo gene therapy approach to treat muscular dystrophy using inducible pluripotent stem cells
Patient-specific induced pluripotent stem (iPS) cells hold great potential for regenerative cell therapies. Here Filareto et al. genetically correct iPS cells from mice with muscular dystrophy and use these cells to treat the same animals, providing a proof-of-principle for autologous iPS cell therapy.

Direct isolation and RNA-seq reveal environment-dependent properties of engrafted neural stem/progenitor cells
Studies on neural stem and progenitor cells have shown they may be useful in treating spinal cord injuries, but the results are variable. Kumamaruet al.transplant these cells in injured spinal cords of mice, and find that their therapeutic properties are dynamically altered depending on their environment.

Muscle-derived stem/progenitor cell dysfunction limits healthspan and lifespan in a murine progeria model
The function of adult stem cells is diminished with age but the role this dysfunction plays in the aging process is unknown. Here, the injection of muscle-derived stem/progenitor cells from young mice rescues symptoms in progeroid mice and is shown to regenerate tissues independent of engraftment.
