Cells are capable of sensing the differences in elastic and viscous properties (i.e., the ‘viscoelasticity’) of their tissue microenvironment and responding accordingly by changing their transcriptional activity and modifying their behaviors. When designing viscoelastic materials to mimic the mechanical properties of native tissue niches, it is important to consider the...

Human mesenchymal stem cells (hMSCs) sense and respond to the bulk elastic and viscoelastic properties of their microenvironment, as well as the spatial distribution of these mechanical signals. Hydrogel substrates with photo-controlled mechanical properties can allow one to probe the cellular response to localized variations in substrate viscoelasticity. Here, we...

Utilizing polymers in cardiac tissue engineering holds promise for restoring function to the heart following myocardial infarction, which is associated with grave morbidity and mortality. To properly mimic native cardiac tissue, materials must not only support cardiac cell growth but also have inherent conductive properties. Here, we present an injectable...

Numerous diseases, including those of the heart, are characterized by increased stiffness due to excessive deposition of extracellular matrix proteins. Cardiomyocytes continuously adapt their morphology and function to the mechanical changes of their microenvironment. Because traditional cell culture is conducted on substrates that are many orders of magnitude stiffer than...

Valvular interstitial cells (VICs) are responsible for the maintenance of the extracellular matrix in heart valve leaflets and, in response to injury, activate from a quiescent fibroblast to a wound healing myofibroblast phenotype. Under normal conditions, myofibroblast activation is transient, but the chronic presence of activated VICs can lead to...

The transcatheter aortic valve replacement (TAVR) procedure has emerged as a minimally invasive treatment for patients with aortic valve stenosis (AVS). However, alterations in serum factor composition and biological activity after TAVR remain unknown. Here, we quantified the systemic inflammatory effects of the TAVR procedure and hypothesized that alterations in...

CU Boulder engineers and faculty from the Consortium for Fibrosis Research & Translation (CFReT) at the CU Anschutz Medical Campus have teamed up to develop biomaterial-based “mimics” of heart tissues to measure patients’ responses to an aortic valve replacement procedure, offering new insight into the ways that cardiac tissue re-shapes...

The American Academy of Arts and Sciences announced today that CU Boulder Professor Kristi Anseth has been elected to its 2019 class. Anseth is among more than 200 individuals selected this year for their exceptional achievements in the arts and sciences, business, philanthropy and the public sector. Founded in 1780,...

Eleven CU Boulder researchers were honored in an annual report released by the firm Clarivate Analytics, which recognizes papers that rank in the top one percent of citations for their field and the year in its Web of Science platform. The CU Boulder researchers span a wide range of disciplines...

The complexities that make each of us unique could result in medications, surgeries or health care devices that treat only the symptoms but not the specific causes. At CU Boulder, engineers are inventing novel biomaterials able to decrease pain and extend life when the body gets out of kilter. And...
