Circulating stem cells play small role in lung repair

A recent study found that circulating stem cells contribute less than 1% to lung repair, while most contributions come from lung-resident stem cells. The study also suggests a link between the number of Y-chromosome containing pneumocytes and acute cellular rejection in lung tissue.

Programmable cells: Engineer turns bacteria into living computers

Scientists have successfully programmed E. coli bacteria to respond to signals and form complex patterns, opening doors for biological computing and medical diagnosis. The breakthrough could lead to applications such as detecting chemicals or organisms in laboratory tests and guiding stem cells for tissue engineering.

Molecular motor implicated in tissue remodeling

Researchers discovered that MMP-1 operates as an extracellular molecular motor converting chemical energy into motion by breaking collagen bonds. This process contributes to tissue growth, development, and repair, and may even aid in cancerous invasion.

Good bacteria trigger proteins to protect the gut

Researchers found that beneficial bacteria trigger proteins called Toll-like receptors to maintain intestinal epithelial cell health and activate machinery for tissue repair. These receptors play a crucial role in protecting tissues from damage and inducing recovery after injury.
