When a scar develops from surgical procedure, harm, or an infection, the encircling tissue transforms. Whereas scar formation has been extensively studied, much less is known concerning the influence of a brand new scar within the tissue microenvironment.
Kshitiz, affiliate professor of biomedical engineering within the UConn College of Dental Drugs, took a better take a look at this scar tissue phenomenon for an article revealed in Nature Communications. In his analysis, accompanied by postdoctoral pupil Wenqian Du, Kshitiz studied the uncommon but life-threatening maternal fetal situation placenta accreta, which happens when the placenta grows too deeply into the uterine wall, to shed some mild on scar tissue.
Cesarean sections, which lead to uterine scarring, are carried out in rising numbers. In parallel, placenta accreta instances are additionally rising. The connection between uterine scarring and placenta accreta appears important, main the analysis workforce to additional query how scarring can set off invasive properties.
The present concept, in line with the researchers, is that the scar is like an “empty road” and the placenta types and strikes into the scar. Kshitiz is skeptical of this standing concept.
“We questioned it because it does not make any sense,” Kshitiz says. “If it’s an ’empty road,’ why doesn’t the mother’s womb cells take the empty road? What we found is that it is not an empty road—the scar is full of collagen.”

The collagen from the scar tissue, the researchers discovered, transforms the endometrium of the mom into an inflammatory state. Utilizing uterine tissue, the researchers created an artificial scar matrix that mimicked placenta accreta. They found that within the case of placenta accreta, a channel opens within the scar tissue, inflicting calcium to infiltrate the endometrium and trigger irritation. When the irritation happens, particular molecules begin aggressively recruiting placental cells in the direction of themselves in a really invasive method.
The researchers now have a greater understanding concerning the implications of scarring, unlocking the likelihood for extra research on scar tissue sooner or later.
“As one of the first major studies on the basic biology of placenta accreta, this discovery opened a whole new area where we can start asking questions about the implications of scars,” says Kshitiz. “By looking at placenta accreta we can learn about the invasive processes caused by scar tissue.”
