Researchers are increasingly making discoveries about how some animals can completely repair their bodies after an injury, whereas we humans cannot. The complete regrowth of lost tissue, for example, hardly ever occurs in adult mammals. Scientists are trying to understand the processes behind this, particularly at the level of the cells in our bodies.
A topic that has recently received a lot of attention is the way cells sense oxygen directly after an injury. This so-called oxygen sensing plays a role in how the body reacts and repairs damage. Although it is not yet clear whether this immediately leads to much better healing in mammals, early results indicate that adjusting this oxygen sensitivity can improve the recovery process.
The study is part of a broader quest within biology to investigate what sets species apart when it comes to their ability to regenerate. Earlier research has already focused on matters such as senescent cells and the immune system. The new work complements that knowledge with a focus on oxygen levels in damaged tissues.
For people who want to age healthily, this is important. Because a better understanding of repair mechanisms can ultimately lead to treatments that support and accelerate our own healing. In this way, a healthier ageing body can remain strong and fit for longer.
