What do we mean by regeneration?

The human body maintains itself primarily by replacing damaged cells.

In humans, it is restricted after birth and is termed wound healing. Some animals have a super-form of wound healing, called regeneration. Regeneration has the capacity to produce biological immortality at the organismal level.

By replacing every cell that gets damaged with a new one, the organism maintains itself indefinitely and exhibits biological immortality.

However, for animals to last for more than one generation, nature had to work out immortality. The sperm and ovary have to revert to age 0 or the baby would be born with the age of the parents and not age 0. This reverting of age is essential to lasting more than one generation.

The baby is built, but if the baby is damaged during the building process, it is detected and the repair is perfect. This system is turned off in an adult and continues to decline with age, if the same damage occurs in an adult, no repair is attempted and scar tissue forms.

So we know the system is in the genome, we just have to yield it as a therapy.

This system is the primary path to reversing some of the hardest pathology in medicine.

This field is called regenerative medicine.

The demonstration of reverting aged cells back to age 0 has got some of the wealthiest people in the world very excited, and the ability to yield a therapy of human regeneration is the challenge. For instance, turning on brain cell regeneration to replace brain cells lost in Parkinson's Alzheimer's and dementia or to repair hearts after heart attacks.

The human system of regeneration is a complex network of cells, tissues, and organs that work together to repair and replace damaged cells and tissues. This system is essential for maintaining health and function throughout life.

The main components of the human system of regeneration are:

Stem cells: Stem cells are undifferentiated cells that can give rise to specialized cells. They are found in many tissues throughout the body, including the bone marrow, skin, and gut.

Growth factors: Growth factors are proteins that signal cells to divide, grow, and differentiate. They are essential for the repair and regeneration of tissues.

Matrices: Matrices are the scaffolding that surrounds cells and tissues. They provide support and structure, and they also help to guide cell growth and differentiation.

Inflammation: Inflammation is a natural response to injury or infection. It helps to remove damaged cells and tissues, and it also promotes the growth of new cells.

The human system of regeneration is constantly working to repair and replace damaged cells and tissues. However, this system declines with age. As a result, older people are more likely to experience injuries and illnesses that take longer to heal.

There is a lot of research being done to find ways to improve the human system of regeneration. This research could lead to new treatments for injuries and diseases, and it could also help people to live longer, healthier lives.

GDF11 is a growth factor that has been shown to play a role in the regeneration of several tissues, including muscle, bone, and nerve. It is thought to work by stimulating the growth of new cells and by promoting the repair of damaged cells.
