Spinach is a leaf that brings plenty of benefits to a person’s health, like decreasing risk of diabetes and potentially preventing cancer. In a recent study, scientists found that the little vein network in the spinach leaves is similar to capillaries in human tissue. Capillaries are considered as the smallest part blood vessels in our body. They link the arteries, which carry blood away from the heart, to the veins, which carry blood back to the heart. Their thin walls also allow for oxygen, nutrients, and waste products to pass between the blood and the tissue of the heart.

If the capillaries don’t finish their work, people are left with diseases such as diabetic retinopathy, and chronic kidney or peripheral neuropathy. In the experiment, the scientist removed the plant cells in the spinach, after that they added the heart cell of humans in it. Surprisingly, the cells began to beat similar to heart tissue. These findings not only have the potential to evolve artificial organ and tissue engineering, but also, can decrease the cost and fees for treatment of diseases involving the heart in the future.

In my opinion, this is a fabulous experiment. The percentage of heart disease in 2025 only continues to increase.  Data indicates that heart disease is becoming a major global problem year after year. In addition, the cost of treatment in the 2000s was around $23,854 per patient, and now in 2025, the total cost has reached nearly $44,447, which is double the amount it was in the 2000s. If this experiment is successful, the advantages of it do not just only make a big step in the field of science, but also can assist people who are underprivileged and suffering from disease to have more options when approaching treatment methods.
