Differentiation And Containment Of Derived Pancreatic Beta Cells, Caden Duffy, Alonzo Cook Ph.D.

Biomedical Engineering Western Regional Conference

Currently, the only permanent cure for Type 1 Diabetes is a pancreatic or islet transplant. With the shortage of donors, we are progressing research towards alternative therapies by differentiating induced pluripotent stem cells into derived pancreatic β-cells that can be transplanted and used as treatment for Type 1 Diabetes. We are investigating methods to increase the yield of fully derived, insulin producing pancreatic β-cells and are additionally researching the use of hydrophilized expanded polytetrafluoroethylene for use in cell containment devices. These devices could offer a future alternative for islet transplantation in human patients.

Despite modern technology and developments in heart disease treatment and prevention, heart disease remains the number one cause of death in America. With an inability to meet an ever-increasing demand for heart transplants and the dangers of immunosuppressant drugs, any potential alternative to cardiac transplantation must be pursued. The end goal of this research is to engineer biocompatible tissues that are fully functional to repair or replace damaged portions of the heart following the loss of cardiac function. This research investigates the effect of porcine extracellular matrix as the scaffold for beating IPS-differentiated cardiomyocytes.

Analysis Of Magnetic Resonance Imaging Of Peripheral Nerve Regeneration, Jaron J. Lundwall, Alonzo Cook 2017 Brigham Young University - Provo

Analysis Of Magnetic Resonance Imaging Of Peripheral Nerve Regeneration, Jaron J. Lundwall, Alonzo Cook

Biomedical Engineering Western Regional Conference

Due to accident related neural damage, many people’s lives are impaired or limited in what they can do. Current medical practices are limited at helping distal and proximal nerve stubs regenerate. Many recent research studies have focused on trying to improve this problem by understanding how cut or crushed nerves heal. Our study hopes to help these efforts by improving non-invasive analysis techniques of nerve growth. Magnetic Resonance Imaging (MRI) is one possible solution to creating a reliable analysis technique that in the future could be used on humans. However, current methods of taking MRI scans involve toxic resolving ...


Developing A Renal Cell Carcinoma Kidney-Tumor-On-A-Chip To Mimic Tumor-Induced Angiogenesis, Connor Tsuchida, Chris Miller, Ying Zheng 2017 University of Washington - Seattle Campus

Developing A Renal Cell Carcinoma Kidney-Tumor-On-A-Chip To Mimic Tumor-Induced Angiogenesis, Connor Tsuchida, Chris Miller, Ying Zheng

Biomedical Engineering Western Regional Conference

Currently, models for testing developing cancer therapeutics are inaccurate. To address this issue, the Zheng Lab is developing a kidney-tumor-on-a-chip to mimic tumor-induced angiogenesis. Initial steps were taken toward this ultimate goal by creating an in vitro study between human kidney microvascular endothelial cells and renal cell carcinoma spheroids. The experiments showed an increase in endothelial sprouts in the presence of renal cell carcinoma spheroids vs. normal kidney cortex spheroids.

Molecular Modeling Of Antibody-Antigen Binding Near Solid Surfaces, Derek Bush, Thomas Knotts 2017 Brigham Young University

Molecular Modeling Of Antibody-Antigen Binding Near Solid Surfaces, Derek Bush, Thomas Knotts

Biomedical Engineering Western Regional Conference

Antibody microarrays are biosensors that have the potential to revolutionize molecular detection in medicine, scientific research, and national defense. However, current microarrays are not widely used due to problems including poor reproducibility and signal quality, unbalanced antibody performance, and cross-reactivity. Prior work in the area focused mainly on the stability of the antibody alone and not its affinity for its antigen. This presentation shows results of using molecular simulation to determine how different types of surfaces affect antigen binding to surface-tethered antibodies. The results offer an unprecedented, molecular-level view into these protein-protein-surface interactions and how to drive binding to occur.


Assessing Dprestin & Nadc1 (Indy) Interaction On Calcium Oxalate Crystal Formation In A Drosophila Model Of Kidney Stones, Jessica Lin 2017 Washington University in St. Louis

Assessing Dprestin & Nadc1 (Indy) Interaction On Calcium Oxalate Crystal Formation In A Drosophila Model Of Kidney Stones, Jessica Lin

Undergraduate Research Symposium Posters

Calcium oxalate (CaOx) accounts for >70%of kidney stones, yet why CaOx stones form is poorly understood. While several factors contribute to the stone aggregation and growth, elucidating the roles of oxalate transporters can help demystify this phenomenon. Using a Drosophila model to study the formation and inhibition of CaOx crystals in the fly Malpighian tubule (MT), oxalate transport via dPrestin—the fly Slc26a6 Cl-/Ox2- exchanger was studied using both electrophysiology and MT dissection with CaOx birefringence assays. Here, the fly model suffices as it recapitulates renal oxalate excretion. Additionally, the mammalian dicarboxylate transporter NaDC1 (Indy in Drosophila ...


Phylogenomic Analysis Of Copepoda (Arthropoda, Crustacea) Reveals Unexpected Similarities With Earlier Proposed Morphological Phylogenies, Seong-il Eyun 2017 University of Nebraska - Lincoln

Phylogenomic Analysis Of Copepoda (Arthropoda, Crustacea) Reveals Unexpected Similarities With Earlier Proposed Morphological Phylogenies, Seong-Il Eyun

Papers from the Nebraska Center for Biotechnology

Background: Copepods play a critical role in marine ecosystems but have been poorly investigated in phylogenetic studies. Morphological evidence supports the monophyly of copepods, whereas interordinal relationships continue to be debated. In particular, the phylogenetic position of the order Harpacticoida is still ambiguous and inconsistent among studies. Until now, a small number of molecular studies have been done using only a limited number or even partial genes and thus there is so far no consensus at the order-level.

Results: This study attempted to resolve phylogenetic relationships among and within four major copepod orders including Harpacticoida and the phylogenetic position of ...

The microreactor was made up of 2 parts including the bioreactor itself and a microchannel network for culture media fluids and microalgae. Both parts were assembled to form a single unit. Additional optical and auxiliar components were added. An external ...


Electrospinning Of Poly (Ester Amide) Fibres For Mesenchymal Progenitor Cell Differentiation, Sarah Kiros 2016 The University of Western Ontario

Electrospinning Of Poly (Ester Amide) Fibres For Mesenchymal Progenitor Cell Differentiation, Sarah Kiros

Electronic Thesis and Dissertation Repository

The in vitro vascular tissue engineering paradigm seeks to produce biologically responsive vascular substitutes using cells, biodegradable scaffolds, and bioreactors to mature the tissue for the potential treatment of vascular occlusions and to create 3D tissue models for pre-clinical testing. In this work, a poly (ester amide) (PEA) derived from from L-phenylalanine, sebacoyl chloride and 1,4 butanediol was synthesized and electrospun to form both 3D fibrous mats and tubular constructs. Both the polymer solution concentration and mandrel rotation speed were optimized to fabricate bead-free fibres. Cytocompatibility and proliferation studies using mesenchymal progenitor 10T1/2 cells showed PEA fibres were ...

Stem Cell Based Tissue Engineering And Regenerative Medicine: A Review Focusing On Adult Stem Cells, Jordan Greenberg, Veronica R. Fortino, Daniel Pelaez, Herman S. Cheung

Veronica Fortino

Tissue engineering has emerged as a field that attempts to harness the bodies' own developmental and repair features to treat diseases and illnesses. Many of these illnesses are caused by necrosis or loss of functionality of complete organs or specific cell types. Early discoveries in embryonic stem cells fueled a wave of research that led to claims about possibly regenerating nonfunctioning organs. Although we are still far away from being able to grow functional organs in a Petri dish, the field continues to progress forward, and new clinical trials have been approved for using both embryonic and adult stem cell ...


Adipose-Derived Stem Cell Differentiation In Cell Aggregates Supplemented With Micronized, Decellularized Extracellular Matrix, Danielle Heinbuch 2016 The University of Western Ontario

Adipose-Derived Stem Cell Differentiation In Cell Aggregates Supplemented With Micronized, Decellularized Extracellular Matrix, Danielle Heinbuch

Electronic Thesis and Dissertation Repository

In the human body there are tissues with limited regenerative potential, raising the need for cell-based regenerative therapies. The main objective of this thesis was to examine how tissue-specific extracellular matrix (ECM) affects the differentiation of human adipose-derived stem/stromal cells (ASCs). The effects of incorporating milled, decellularized adipose (DAT) or cartilage (DCT) ECM particles on ASC lineage-specific differentiation in 3-D cell aggregate cultures were explored. The results demonstrated that the addition of ECM improved differentiation for both adipogenesis and chondrogenesis. Analysis of adipogenic gene and protein expression indicated enhanced differentiation in the DAT+ASC aggregates relative to the DCT ...


Characterization Of Histological Changes In The Microvasculature Of Rat Skeletal Muscle After Spinal Cord Injury, Sally Lin 2016 Marquette University

Characterization Of Histological Changes In The Microvasculature Of Rat Skeletal Muscle After Spinal Cord Injury, Sally Lin

Master's Theses (2009 -)

The purpose of this study was to determine whether there are histological changes in the microvasculature of rat skeletal muscle following chronic spinal cord injury both above and below the level of injury. This study is important because microvascular structure likely impacts muscle performance and cardiovascular health. To the best of our knowledge, this is the only study to investigate microvascular structure within rat skeletal muscle after spinal cord injury. We hypothesized structural remodeling would occur in both the myofibers and microvasculature, which would then manifest in differences in myofiber cross sectional area and microvascular diameter, wall thickness, wall to ...

Bone Tissue Engineering: Scalability And Optimization Of Densified Collagen-Fibril Bone Graft Substitute Materials, John G. Nicholas, Lauren E. Watkins, Sherry L. Voytik-Harbin

The Summer Undergraduate Research Fellowship (SURF) Symposium

Over 240 million people missing teeth worldwide experience lingering problems such as difficulty speaking and eating, undesirable aesthetics, and resorption of bone supporting neighboring teeth. The gold standard of treatment utilizes grafts to attach a function-restoring implant to supporting bone. Current graft materials suffer from problems including autologous donor site morbidity, long resorption time, incomplete integration with the maxillae or mandible, and structural weakness. Patient-specific, cellularized bone grafts may be a solution to these issues by accelerating and improving the quality of regenerated bone. Recently, encapsulation of mesenchymal stem cells within self-assembling type I collagen oligomer matrices has been shown ...
