Ultrasonically Responsive Tissue Engineering Scaffolds For The Temporal Control Over Osteo-Inductive Growth Factor Delivery, Catherine Linh
Ultrasonically Responsive Tissue Engineering Scaffolds For The Temporal Control Over Osteo-Inductive Growth Factor Delivery, Catherine Linh
Senior Honors Projects
In 2012, approximately 6.8 million people in the United States were diagnosed with orthopedic injuries or diseases. Over 500,000 people in the United States underwent bone grafting procedures, which cost 2.5 billion dollars per year and can result in complications. Polymer-based grafting scaffolds can facilitate 3D bone tissue growth in a localized, sustained manner. However, bone regeneration requires the orchestration of a sequence of events. Current scaffolds based on degradation and diffusion cannot provide sequential deliveries. We aimed to design a polymer scaffold that can release one payload diffusively at early time points, followed by ultrasonically triggered release of a …
Patient-Derived Hydrogel As A Sacrificial Matrix For Efficient Cell Loading, Shalmli U. Joshi
Patient-Derived Hydrogel As A Sacrificial Matrix For Efficient Cell Loading, Shalmli U. Joshi
Honors Scholar Theses
The field of tissue engineering focuses on delivering patient-derived stem cells to the body through the use of degradable biomaterials, such as hydrogels, which are infused into engineered scaffolds. Hydrogels act as templates to support and guide cells towards the regeneration of new tissue. In this study, we introduce a completely intraoperative procedure for obtaining a fibrin hydrogel for tissue engineering applications. In the past, fibrin hydrogel has been commonly formed by combining fibrinogen protein with animal-derived thrombin. Instead, we have developed an automated, and therefore reproducible, protocol to isolate and form fibrin hydrogel without the use of animal-derived thrombin. …
Polysaccharide Fabrication Platforms And Biocompatibility Assessment As Candidate Wound Dressing Materials, Donald C. Aduba Jr., Hu Yang
Polysaccharide Fabrication Platforms And Biocompatibility Assessment As Candidate Wound Dressing Materials, Donald C. Aduba Jr., Hu Yang
Chemical and Biochemical Engineering Faculty Research & Creative Works
Wound dressings are critical for wound care because they provide a physical barrier between the injury site and outside environment, preventing further damage or infection. Wound dressings also manage and even encourage the wound healing process for proper recovery. Polysaccharide biopolymers are slowly becoming popular as modern wound dressings materials because they are naturally derived, highly abundant, inexpensive, absorbent, non-toxic and non-immunogenic. Polysaccharide biopolymers have also been processed into biomimetic platforms that offer a bioactive component in wound dressings that aid the healing process. This review primarily focuses on the fabrication and biocompatibility assessment of polysaccharide materials. Specifically, fabrication platforms …
