Cellular Regeneration
The human body has an innate ability to heal itself, given the tools and environment needed to effectively sustain itself.
Cellular regeneration which is a form of cell repair is also possible. This restoration and renewal of cells precede the goal to eventually restore an affected organ.
Most organs are easier to regenerate than others. The liver is generally grows and repairs itself in the event of an injury during a disease. Our skin, the largest organ in the body consistently repairs itself at the cellular level.
The process of regenerative medicine is intriguing and currently serves to continuously explore effective paths towards cellular and tissue replacement.
