Japan Hospital Conducts First Surgery Using Heart Muscle Stem Cells

A hospital in Japan has successfully performed the world’s first surgery using sheets of heart muscle stem cells. This innovative procedure took place on Tuesday and was made possible after the treatment received government approval earlier this year.

During the hour-long surgery, sheets made from induced pluripotent stem cells (iPS cells) were transplanted into the heart of a woman in her 50s. These cells can develop into various types of cells in the body, offering new hope for patients with heart conditions.

Surgeon Yoshiki Sawa, who leads the team at Osaka Keisatsu Hospital, expressed optimism about the procedure, stating that it aims to enhance the patient’s quality of life. The therapy is particularly designed for heart patients who have not found relief from other treatments.

Prior to this surgery, trials involving eight patients suffering from ischemic heart disease, which is caused by narrowed heart arteries, showed promising results. All participants reported an improvement in their symptoms, and four of them experienced better heart function.

Sawa’s team plans to perform similar surgeries on 75 patients by 2033 and will monitor the treatment’s effectiveness over time. If proven safe and beneficial, the therapy could receive full authorization in the next seven years.

In addition to this heart treatment, Japan has also approved a Parkinson’s disease therapy that uses iPS cells to help patients. This approach to medicine represents a significant step forward in regenerative therapies.
