In addition to replacing senescent cells, stem cell anti-aging can also secrete some growth factors and cytokines, improve the body's ability to resist free radicals, stimulate the regeneration and repair function of tissue cells, and achieve the purpose of repair and anti-aging.
What is Aging?
Aging is the degenerative changes in the function of tissues and organs that occur with the growth of age, which is manifested as a progressive decline in the functional activity ability of the body, a gradual decrease in the ability to adapt to the environment, and an imbalance of metabolic balance in the body, resulting in a series of aging symptoms such as old complexion, sagging, increased wrinkles, easy fatigue, decreased mental and physical work ability, and decreased sexual function.
The nature of aging
Aging is characterized by a decrease in the ability of cells to regenerate and a decline in the function of tissues and organs. The human body is a "cellular society" made up of about 40-60 trillion cells with different physiological characteristics. 1% 2% of cells die every day, and 1% of cells are reborn every day. And stem cells are the mother of this "cell society". With the growth and maturity of individual life, various adult stem cells in the body gradually decrease, and even completely disappear in some tissues and organs.
Stem cells are a kind of multipotent cells with self-replication ability, which can differentiate into a variety of functional cells under certain conditions, and have high telomerase activity, so they are "forever young" and can always differentiate. Studies have proven that stem cells have significant efficacy in cardiovascular diseases, metabolic diseases, Parkinson's syndrome, leukemia and other diseases; Stem cell anti-aging was one of the top 10 scientific advances in 1999 selected by Science magazine, which triggered the revolution of "regenerative medicine".
In addition to replacing senescent cells, stem cell anti-aging can also secrete some growth factors and cytokines, improve the body's ability to resist free radicals, stimulate the regeneration and repair function of tissue cells, and achieve the purpose of repair and anti-aging. For example, vascular endothelial growth factor, platelet-derived growth factor and transforming growth factor can promote the synthesis and conversion of collagen and help smooth wrinkles.
In 2007, British scientist Anastasia wrote an article in the journal Nature pointing out that adult stem cells are essential for the human body to repair itself and regenerate tissues, and the reduction of adult stem cells is the main reason for human aging. This discovery has important implications for understanding the aging process, which is why stem cell and regenerative medicine research has flourished in recent years.
Anti-aging is not just a matter for the elderly, but something that people of every age should pay attention to. When you are young, you should establish the concept of anti-aging, cultivate healthy behavior Xi, and after a certain age, you will not be old or disease-ridden.
The two mountains at the foot of Bezos, the world's richest man, one called Amazon, have rewritten the history of human transactions; The other is called Blue Origin, which directly competes with SpaceX, the "Iron Man", and pioneered the first human space travel...However, the 57-year-old richest man is now spending a lot of money on technology that "prolongs human life."
When does the anti-aging program start?
Anti-aging at the age of 30, maintain youthful beauty and health
The age of 30 is the starting point for most organ aging. From the age of 30, the elasticity of the ear drum and the ossicle bone of the middle ear begins to weaken, and hearing declines. The weight of the brain has also been reduced from the heaviest 1600g at this time; Although the so-called "presbyopia" is not noticed until the age of 40, it actually begins to change from the age of 30; The lungs become less elastic and age slowly from the age of 30; From the age of 30, muscles are decreasing at a rate of 5% to 10% per year.
Therefore, 30 years old is the best time to fight aging. Anti-aging begins at this time, which can continue the ideal state of health for a long time. The main purpose of anti-aging at this stage is to maintain youth and health, and if the anti-aging preparation at this stage is done well, it will be of great help to slow down aging.
Anti-aging at the age of 40, slow down the rate of aging, and prevent chronic diseases
Middle-aged people in their forties have begun to age and are about to enter the stage of old age. However, if you start anti-aging at the age of 40, as long as you do it properly, you will still get certain results. On the contrary, if you do not pay attention to anti-aging maintenance, a series of bodily functions may accelerate aging and increase the risk of various diseases such as cardiovascular and cerebrovascular, kidney, and endocrine system.
The latest genetic study by researchers at Harvard Medical School in the United States believes that the aging of brain tissues related to learning Xi, memory, and cognitive function begins at the age of 40. Anti-aging from this period can prevent and delay the decline of brain memory function, partially restore physical energy and energy, delay the arrival of menopause, and improve the quality of life. The focus of anti-aging at this stage is to slow down the rate of aging, prevent the occurrence of chronic diseases, and maintain the mentality of young people.
Anti-aging at the age of 50, slowing down and preventing aging
People over the age of 50 may already have signs of disease in their bodies, and even suffer from certain diseases, and people in this age group are at a very high risk of cardiovascular and cerebrovascular diseases and cancer due to the dual pressure of society and family. Even if there is no disease to disturb people, the body organs are already aging and have obvious signs of aging. Therefore, the focus of anti-aging at this stage should be on preventing and delaying the occurrence of diseases, reducing the impact of diseases on quality of life, preventing and improving menopausal symptoms, and improving physical strength, concentration and memory.
60-year-old anti-aging, prolonging life
60 years old is a very late anti-aging opportunity, at this time the symptoms of aging have been quite obvious, this stage of anti-aging focus needs to shift from functional preventive anti-aging, to the prevention of age-related diseases. The anti-aging** effect from this age is far less than that of anti-aging from the age of 30, but given the huge physiological differences between the elderly and young people, autologous stem cell transplantation can still provide effective help to improve the quality of life and prolong life.
The US FDA has approved stem cells to improve wrinkles and cosmetic appearance in the nasolabial folds**. As the frontier field of medical research, stem cell technology has a promising future.
