Scientists are developing a new technique to help heart patients recover by injecting bone marrow into scarred heart tissue. Initially tested on animals, this method is now being trialed on humans. The technique involves using the patient's own bone marrow to promote natural heart regeneration. Early results are promising, showing improved heart function in treated areas. The study is expanding to include more patients and explore applications in other body parts, potentially leading to regenerative treatments for the liver, brain, and other tissues.

What is the primary goal of the new technique being developed by scientists?

• To improve the efficiency of heart bypass operations

• To help the heart regenerate naturally

• To replace heart tissue with artificial materials

• To reduce the cost of heart surgeries

How were the patients' hearts examined after the surgery?

• Clinically and using echo scanning techniques

• By monitoring heart rate

• Through blood tests

• Using MRI scans only

What was the outcome of the initial tests on the 14 patients?

• The patients experienced severe side effects

• The fibrotic parts of the heart began to beat again

• The heart tissue showed no change

• The heart tissue was replaced with new cells

What is the next step in the study of this technique?

• To apply the technique to children

• To halt the study due to negative results

• To conduct tests on animals

• To expand the study to 60 patients

Which other organs might benefit from this bone marrow technique if successful?

• The lungs and kidneys

• The liver and brain

• The stomach and intestines

• The skin and eyes
