The study was published online ahead of print in the journal Cell. Induced pluripotent stem cells (known as iPSCs) are similar to human embryonic stem cells in that both cell types have the unique ability to self-renew and have the flexibility to become any cell in the human body. iPSC cells, however, are generated by reprogramming skin or blood cells and do not require an embryo. Reprogramming is a long process (about one to two weeks) and largely inefficient, with typically less than one percent of the primary skin or blood cells successfully completing the journey to becoming an iPSC. The exact stages a cell goes through during the reprogramming process are also not well understood. This knowledge is important, … Continue reading →

By: Adam Feuerstein | 01/05/15 - 10:52 AM EST Once injected, the NurOwn stem cells bathe the damaged neurons of ALS patients with secretions of nerve growth factors. Brainstorm has a home run on its hands if NurOwn can be shown to slow or halt the progressive destruction of neurons, and if that disease-modifying effect translates into improved muscle function for ALS patients. Monday's update comes from a Phase IIa trial in which 14 ALS patientswere followed for the three months without treatment. At month four, each patient wastransplanted with their own personalized NurOwn therapy and then assessed every month for six months. Brainstorm evaluated NurOwn's impact on ALS disease progression using the ALSFRS score, a commonly used assessment of treatment response and muscle function in ALS patients. Lung function, another commonly used measure of efficacy in ALS clinical trials, was also measured. Twelve ALS patients were evaluable for response. Of these, 11 patientsshowed aslowing of ALS disease progression at six months compared to baseline, measured either by improved ALSFRS or lung function scores, Brainstorm said. Two other patients enrolled in the study died. Administration of the NurOwn therapy was well tolerated by patients, the company said. The final Phase … Continue reading →
