Scientists had a eureka moment when their age-reversing research discovered a key component in a pea-sized part of the brain. As we age, cell reproduction declines, and by replenishing stem cells, it may be “possible to slow and even reverse various aspects of aging throughout the body” according to the researchers.

A study published in the scientific journal Nature and carried out by Dongsheng Cai, from the Albert Einstein College of Medicine in New York, focused on the hypothalamus in their mice trials. The hypothalamus is responsible for bodily functions and influences our body’s temperature control, blood pressure, heart rate, appetite, digestion, libido, and sleep patterns. The tiny neurons of the hypothalamus also appear to have an impact on aging. 

As explained by Professor Cai, the number of hypothalamic neural stem cells naturally declines and accelerates aging. The effects are not irreversible but can be paused as seen in their mice trials. Injecting stem cells slowed and in some cases, reversed the process of aging on the mice subjects when they measured various data. It is believed that the microRNAs (miRNAs) pair up with the body’s “messenger” RNA molecules to regulate the gene activity by turning off certain genes. 

For now, anti-wrinkle injections and platelet-rich plasma (PRP) treatments remain the most successful in improving skin quality and reducing the aging process.
