Importantly, the researchers discovered that melanoma patients who have PTEN mutations and higher levels of fibronectin in their tumors tend to have a lower overall survival. (sciencedaily.com)
In the study, published in Obstetrics and Gynecology, researchers compared measurements of this new fetal fibronectin test in the vaginal fluid of women at 18 to 21 weeks of gestation with measurements made at 22 - 27 weeks of gestation, to see which time period offered the best prediction of spontaneous preterm birth.

They then printed a patterned layer of a protein called fibronectin to which rat heart cells then attached. (sciencemag.org)
