CANBERRA: Australian researchers have discovered new cells in a world-first that they say could enhance future human tissue repair and generation.
In a study published on September 23, a team from the South Australian Health and Medical Research Institute discovered the cells that can transform into two previously-known types of cells: endothelial cells that form blood vessels and macrophages, which are responsible for tissue repair and defence.
Named EndoMac progenitors, the new cells were discovered in the outer layer of aortas in adult mice. The team said that the existence of cells with similar functions has been theorised for over a century but that they had never been found. The discovery was the result of nine years of work by the researchers. They found that the cells are activated by injury or poor blood flow, at which point they rapidly expand to aid healing, Xinhua news agency reported.
Ongoing research suggests that the EndoMac progenitors could be used to boost healing in conditions like diabetes where the body struggles to properly repair itself.
“When we transplanted these progenitors into diabetic wounds, we saw a dramatic improvement in healing within days,” Sanuri Liyange, a member of the research team, said in a media release. She said the discovery was a promising development for creating more effective treatments.
