Platelets respond to surfaces with greater stiffness by increasing their stickiness, the degree to which they “turn on” other platelets and other components of the clotting system, researchers have found. Platelets, the tiny cell fragments whose job it is to stop bleeding, are very simple. And yet they have proven to be “smarter than we give them credit for,” researchers have found.

Platelets, the minor cell fragments whose function it is to staunch bleeding, are exceptionally basic. They don't have a cell core or nucleus. At the same time they can “feel” the physical environment around them, analysts at Emory and Georgia Tech have found. Platelets react to surfaces with more prominent solidness by expanding their stickiness, the degree to which they “turn on” different platelets and different segments of the coagulating framework, the analysts found. “Platelets are more intelligent than we provide for them credit for, in that they find themselves able to sense the physical qualities of their surroundings and react in a graduated manner,” says Wilbur Lam, MD, Phd, associate educator in the Department of Pediatrics at Emory University School of Medicine and in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University. The results are distributed in Proceedings of the National Academy of Sciences. The main researcher of the paper is a research associate by the name of Yongzhi Qiu. Lam is likewise a doctor in the Aflac Cancer and Blood Disorders Center, Children's Healthcare of Atlanta.
