Harnessing Notch Signaling For Biomaterial Scaffold-Based Bone Regeneration, Helena P. Lysandrou, Chunhui Jiang, Naagarajan Narayanan, Shihuan Kuang, Meng Deng
The Summer Undergraduate Research Fellowship (SURF) Symposium
Bone fracture has recently become prevalent, especially with an increasingly aging population. Current bone grafts procedures, including autografts and allografts, are hindered by multiple factors, such as limited supplies and inconsistent bone healing. Scaffold-based bone tissue engineering emerges as a prospective strategy to aid in bone regeneration through delivery of growth factors such as bone morphogenic proteins (BMPs). However, the use of BMPs suffers from several drawbacks such as protein instability and immunogenicity. Therefore, there exists a great need for the development of novel therapies to promote bone healing. Notch signaling, a pathway critical for cell-fate determination has been shown …

Development Of A Novel Enzymatic Pre-Treatment For Lignocellulosic Biomass, Melissa Robins, Jenna Rickus
The Summer Undergraduate Research Fellowship (SURF) Symposium
Biofuels, fuels derived directly from living matter, present a renewable and environmentally friendly alternative to petroleum based fuels. Bioethanol produced from low input energy crops or agricultural waste is a promising fuel source because it does not interfere with the human food supply chain and the ethanol produced can be blended with gasoline. These potential sources of bioethanol are not yet commercially viable due to a polymer called lignin present in the plant’s cell wall which impedes the conversion of cellulose to glucose and the eventual fermentation of glucose to ethanol. Developing new methods for the pretreatment of lignocellulosic biomass …

Skeletal muscles can self-repair minor strains, lacerations, and contusions; however, in cases of volumetric muscle lossand muscle degenerative diseases, tissue fails to regenerate. Current cell-based therapies, such as myoblast transplantation, have significant drawbacks of low survival rates and engraftment efficacy, mainly due to the absence of supportive cell microenvironment. Scaffolds that mimic the natural cell microenvironment provide a robust platform to support cell adhesion, migration, proliferation, and differentiation. Electrospinning is a versatile technology platform used for fabricating the fiber scaffold that mimics the extracellular matrix. Thus, we aim to reconstitute the cell microenvironment through development of aligned fiber scaffolds by …

Lignin, a complex organic polymer, is a major roadblock to the efficiency of biofuel conversion as it both physically blocks carbohydrate substrates and poisons biomass degrading enzymes, even if broken down to monomer units. A pretreatment process is often applied to separate the lignin from biomass prior to biofuel conversion. However, contemporary methods of pretreatment require large amounts of energy, which may be economically uncompelling or unfeasible. Taking inspiration from several genes that have been isolated from termites and fungi which translate to enzymes that degrade lignin, we want to establish a novel “enzymatic pretreatment” system where microbes secrete these …

Patients with kidney failure usually undergo hemodialysis, a process by which toxins produced by the body are filtered from the blood, in order to survive. The preferred form for vascular access is called an arteriovenousfistula (AVF), a surgically created connection between an artery and vein that is utilized to undergo dialysis. However, AVFs have a failure rate of 50-60%. One of the contributions to AVF failure is endothelial cell dysfunction and loss of glycocalyx, which allows neutrophils and other native cells into the media of the vessel, which causes an inflammatory response. Our lab addresses endothelial dysfunction by mimicking the …
