A study, by bioengineers at the University of Notre Dame, talks about a new strategy that can restore damaged stem cells, and enable them to grow new tissues again. Under the new strategy, each damaged stem cell is given a nanoparticle backpack. [1]

This is one of the major reasons parents, these days, opt to store the blood in an infant’s umbilical cord. Notably, if pregnancies get affected by gestational diabetes, the stem cells of the umbilical cord get damaged, making the cord useless. However, a study, by bioengineers at the University of Notre Dame, talks about a new strategy that can restore the damaged stem cells, and enable them to grow new tissues again. Under the new strategy, each damaged stem cell is given a nanoparticle backpack. [2]

Figure 1 shows according to the to learneach spherical nanoparticle with a diameter of 150 nanometers has the ability to store the drug and slowly transfer it to the stem cells.

Donny Hanjaya-Putra, Assistant Professor of Aerospace and Mechanical Engineering, Graduate Program in Bioengineering at Notre Dame, said, “Each stem cell is like a soldier. It’s smart and effective; it knows where to go and what to do. But the “soldiers” we work with are injured and weak. By providing them with this nanoparticle ‘backpack’, we’re giving them what they need to get back to working effectively.” [3]

The Researchers then performed an experiment to remove damaged cells. “backpacks”. After Examining The cells showed that they had formed inept tissues. They formed inept tissues.The result is “backpacks” Theformation of new blood vessels has been demonstrated. [4]

Hanjaya-Putra and his team think that this approach can come in handy during pregnancy complications, such as preeclampsia. The researcher added, “Instead of discarding the stem cells, in the future, we hope clinicians will be able to rejuvenate them and use them to regenerate the body.” Citing an example, Hanjaya-Putra added, “For example, a baby born prematurely due to preeclampsia may have to stay in the NICU with an imperfectly formed lung. We hope our technology can improve this child's developmental outcomes.” [5]
