The interdisciplinary group of Cathal Kearney, assistant professor of biomedical engineering, and Govind Srimathveeravalli, assistant professor in mechanical and business engineering, has gained the 2023 Armstrong Fund for Science Award.
Starting in September, the pair will obtain a two-year, $40,000 grant for his or her analysis challenge, “You Can Educate an Outdated Canine Younger Methods: Bettering Wound Therapeutic Thru Rejuvenated Biomaterials.”

Construction on discoveries in each and every in their labs, Kearney and Srimathveeravalli will paintings in combination to broaden a brand new option to pace the therapeutic procedure in hard-to-heal wounds.
“We can examine using younger and rejuvenated extracellular vesicles for the primary time to boost up wound therapeutic,” the group states of their challenge summary. “With 1-2% of the inhabitants growing a prolonged wound of their lifetime, our discoveries are urgently had to lend a hand sufferers.”
Benefactors John and Elizabeth Armstrong established their Fund for Science in 2006 to spot and fortify UMass Amherst researchers with promising, daring initiatives that can problem conventions of their box. Early-career school who’re girls or participants of teams which are underrepresented in science, era, engineering and arithmetic (STEM) are particularly inspired to use.
The Kearney Lab objectives to engineer equipment to reinforce tissue restore and regeneration by way of working out and mimicking herbal organic cue timing. Whilst younger and rejuvenated cells, equivalent to triggered pluripotent stem cells (iPS), boost up wound therapeutic, their medical translation is prohibitively pricey and sophisticated by way of regulatory limitations.
Kearney used to be in a position to construct fabrics the usage of the extracellular matrix (ECM) and extracellular vesicles (EVs) secreted by way of those cells, making a method to exploit their rejuvenating advantages with out the usage of the cells themselves.
“The Kearney Lab used to be the primary to manufacture the sort of rejuvenated ECM, the usage of iPS-reprogrammed and re-differentiated cells, demonstrating that those biomaterials directed elderly and diseased cells to act like younger and wholesome cells,” the summary states.
In the meantime, the Srimathveeravalli Analysis Team develops novel scientific gadgets for power supply in vitro and in vivo by way of finding out the interplay of non-ionizing power and biology at multiscale solution, from cells via organ methods. Srimathveeravalli and his group use laptop simulations to fashion organic reaction after publicity to power and to design power parameters that elicit particular responses.
Whilst Kearney’s paintings centered at the ECM scaffold, Srimathveeravalli generated new knowledge demonstrating enrichment of EVs inside those scaffolds. Those EVs are naturally produced nanoparticle therapeutics that may arrange homeostasis, restore and regeneration.
The Armstrong Fund evaluation panel remarked no longer handiest at the power and novelty of the Kearney-Srimathveeravalliproposed analysis, however at the researchers’ robust are compatible for Armstrong Fund priorities.
Armstrong Fund for Science grants are awarded once a year. Proposals are decided on for awards via an inside restricted submission procedure administered by way of the Administrative center of Analysis Building.
