The role of trillions
of body cells in sustaining a perfect health
Cells, or the “building blocks of life”, are small units that form and control the body throughout its lifetime. These fundamental molecules are not homogeneous, but rather, consist of a varied and complex assemblage of different types of cells, such as blood cells, bone cells, cardiac cells and pancreas cells. They can multiply at a phenomenal rate: for instance, during the first days of a foetus, new brain cells multiply at the outstanding rate of 25,000 cells per minute, a rate which only increases faster until birth,
at a pace of one million cells per minute.
The natural cell cycle from the first day of birth, and under normal conditions, consists of a three-step process: first, the body cells are produced, second, they become active, and finally, they decline. Children can regenerate cells, which means that when they become ill or injured, they can recover faster than adults, because their C.R.M™ -which varies from person to person- still functions. This lasts until a person reaches the approximate age of 25, after what the body’s capacity to regenerate cells declines. Hence, the older a person gets, the longer it will take for his or her body to recover from an illness or an injury, and consequently, this is linked to a decrease in cell regeneration.
7 Responsible factors
for C.R.M TM
Inherited genetics affect cells and their functioning in different ways. Indeed, a human cell consists of 23 pairs of chromosomes. A chromosome, in turn, has 6 billion of DNA base pairs, and 20,000 to 25,000 genes that control the production of proteins. Thus, a slight genetic difference (0.01%) can affect the protein production essential to the well-functioning of cells as well as of that of enzymes, neurotransmitters, etc.
A stem-cell niche is the area which surrounds a stem cell, and interacts with it by sending signals that stem cells should “rest” as well as by stimulating them so that they produce new cells when the tissue becomes damaged.
Mitochondria are organelles that can be found inside body cells. Equipped with their own DNA as well as a capacity to synthesize proteins, they are responsible for cell energy production, and regulating calcium levels in cells, cell metabolism, and apoptosis or a cell’s death. Thus, these are fundamental to the fuelling of body cells’ energy.
A telomere is a cap that protects the end of each strand of the DNA. The telomere becomes shorter when cells start to divide, which a process that occurs through life. As a person gets older, telomers shorten, which means that they can no longer protect the end of each DNA stand. This weakens the DNA, which in turn may result in a number of malfunctions and potential health problems.
Free radicals stemming from cellular metabolic activities and pollutants can disturb body cells. These free radicals are classified as Reactive Oxygen Species (ROS) and Reactive Nitrogen Species (RNS). When the free radical accumulation increases, it causes oxidative stress which is harmful to proteins, fat, DNA and cells in the body. This damage can cause serious health conditions such as stroke, atherosclerosis, diabetes, and high blood pressure.
A hormone is a regulatory substance that stimulates the cells’ activities in the body. They have been documented to have different physical and psychological influences on women.
In 1997, Kuro-o et al. discovered a new protein called Klotho. The researchers found that klotho was connected to several manifestations of a chronic renal disease, causing signs of aging (i.e., wrinkling), as well as atherosclerosis, and osteoporosis. According to another experiment, lab rats who had more Klotho genes lived between 19-31% longer than normal lab rats.
Cells, the smallest unit of our body, never stop functioning since the first day of life to its end.
The body consists of fifty billion units of cells that are separately responsible for particular functions. The cellular regeneration, as well as the cellular degeneration, should correspond to each other to the benefit of a regular pattern of apoptosis. The abnormal cell growth would likely to cause a tumor. There are two types of tumor: benign tumor and malignant tumor. A benign tumor is a noncancerous, non-spreading lump of cells with a low rate of growths, while a malignant tumor can spread to other parts of the body and tend to cause cancer.
