Expression Optimization Of The Gst-Gfp Fusion Protein Through The Alteration Of Induction Conditions, Matthew J. Vaccaro
Expression Optimization Of The Gst-Gfp Fusion Protein Through The Alteration Of Induction Conditions, Matthew J. Vaccaro
Honors Undergraduate Theses
This research sought to determine which induction condition resulted in the greatest GST-GFP fusion protein expression. It will hopefully serve as a guide for future researchers trying to produce their own recombinant protein containing GST and GFP-tags. The CDNB Enzyme Assay was used to determine the quantity of GST-GFP fusion protein present and tested three variables: IPTG concentration, duration, and temperature of induction. The findings showed that IPTG concentration, temperature, and induction duration all had a significant impact on protein expression. Induction temperatures of 20 °C and 25 °C showed better protein expression at IPTG concentrations of 1.0 mM IPTG …

Mesenchymal Stromal Cell And Chondrocyte Mobility In 3d Bioprinted Hydrogel Constructs, Alesia Lokshina
Honors Undergraduate Theses
Osteoarthritis (OA) is a progressive cartilage degeneration disease with a complex pathologic mechanism. Although OA has devastating effects on patient quality of life and places a significant burden on the healthcare system, no disease-modifying drugs have been found, and surgical treatment options are often unsustainable. 3D bioprinting is a novel field within tissue engineering that focuses on developing biocompatible constructs that can be implanted to replace an organ or tissue. Such constructs have a great potential to become treatments for OA. Understanding cell mobility within hydrogels could play a vital role in advancing the development of biocompatible constructs. However, due …
Multifactorial Media Analysis Via Design Of Experiment For Type Ii Collagen In Primary Rabbit Chondrocytes, Javier A. Velez Toro
Multifactorial Media Analysis Via Design Of Experiment For Type Ii Collagen In Primary Rabbit Chondrocytes, Javier A. Velez Toro
Honors Undergraduate Theses
Osteoarthritis is a prevalent disease that affects the articular cartilage of the joints. Millions of people suffer worldwide and it is a major cause of disability in the United States. Current research for treatments of osteoarthritis are studying tissue-engineered cartilage in vitro generated by articular chondrocytes. A challenge faced in vitro for cartilage tissue engineering is the failure of chondrocytes to produce adequate expression of type II collagen. Surprisingly, the media commonly used in vitro lacks 14 vitamins and minerals present in the physiological environment of chondrocytes. Therefore, studying the interactions between micronutrients and chondrocytes may help in potentially increasing …
Using A Lubricin Reporter Cell To Test Current Vs. Optimized Media Compositions, Sean M. Kennedy
Using A Lubricin Reporter Cell To Test Current Vs. Optimized Media Compositions, Sean M. Kennedy
Honors Undergraduate Theses
Osteoarthritis is a joint disease characterized by the breakdown of articular cartilage. The field of tissue engineering is interested in developing methods to produce biological alternatives to current orthopedic procedures. Lubricin is a molecule which is important in the proper lubrication of articular cartilage. It is a challenge in the field of tissue engineering to produce cartilage with sufficient lubricin expression. Developing a reporter cell for lubricin allowed for a more efficient investigation of the conditions which may influence its expression. By comparing "optimized" and traditional media solutions, it was determined that the use of a previously reported type II …

Assessing 3d Printability Of Bioinks, Nicole Ramirez
Honors Undergraduate Theses
The field of tissue engineering (TE) is continuously improving through the use of additive manufacturing techniques (AM) such as three-dimensional (3D) bioprinting. The 3D bioprinter has significantly gained attention in the TE field because it is more efficient than regenerative medicine and is readily available as opposed to organ transplants. Working like a conventional 3D printer, the 3D bioprinter is able to dispense material layer by layer from the bottom up with the printing head able to move in the X, Y, and Z direction. This movement allows for the fabrication of structures with complex geometries. In this study, the …
The Effects Of Emerging Technology On Healthcare And The Difficulties Of Integration, Skyler J. Pavlish-Carpenter
The Effects Of Emerging Technology On Healthcare And The Difficulties Of Integration, Skyler J. Pavlish-Carpenter
Honors Undergraduate Theses
Background: Disruptive technology describes technology that is significantly more advanced than previous iterations, such as: 3D printing, genetic manipulation, stem cell research, innovative surgical procedures, and computer-based charting software. These technologies often require extensive overhauls to implement into older systems and must overcome many difficult financial and societal complications before they can be widely used. In a field like healthcare that makes frequent advancements, these difficulties can mean that the technology will not be utilized to its full potential or implemented at all.
Objective: To determine the inhibiting factors that prevent disruptive technology from being implemented in conventional healthcare.
Methods: …
