Title: Developing a Synthetic Hydrogel for Breast Tissue Engineering
As part of the PI's outreach, a course-based undergraduate research experience engaged undergraduate women in research from examining the literature to identify a gap, formulating a research hypothesis, designing experiments to test the hypothesis, analyzing the data, writing and submitting an abstract and presenting the research to the scientific community. This project was as follows: Current clinical approaches to repair breast damage from cancer resection, injury, or deformity focus on synthetic implants or autologous muscle grafts. While there are drawbacks and benefits to each, neither restore the function lost should the woman desire to nurse children. Tissue engineering methods have the potential to restore breast tissue volume and function that circumvent the reconstructive limitations of contemporary surgical procedures. There is a large body of research on breast tissue engineering; however, much of the research focuses on restoring breast volume rather than breast function and seek to replace the missing tissue with fat or muscle.​ Here, we aim to develop a scaffold capable of supporting both breast adipose and glandular tissue (the main components of breast tissue) towards restoring both form and function to the breast.  more » « less

  1. Abstract A heart attack results in the permanent loss of heart muscle and can lead to heart disease, which kills more than 7 million people worldwide each year. To date, outside of heart transplantation, current clinical treatments cannot regenerate lost heart muscle or restore full function to the damaged heart. There is a critical need to create engineered heart tissues with structural complexity and functional capacity needed to replace damaged heart muscle. The inextricable link between structure and function suggests that hydrogel composites hold tremendous promise as a biomaterial‐guided strategy to advance heart muscle tissue engineering. Such composites provide biophysical cues and functionality as a provisional extracellular matrix that hydrogels cannot on their own. This review describes the latest advances in the characterization of these biomaterial systems and using them for heart muscle tissue engineering. The review integrates results across the field to provide new insights on critical features within hydrogel composites and perspectives on the next steps to harnessing these promising biomaterials to faithfully reproduce the complex structure and function of native heart muscle.

  2. The myotendinous junction (MTJ) acts as a bridge between muscle and tendon; yet its high stiffness relative to muscle fibers renders the tissue susceptible to injuries due to eccentric loading disparities. The limited regenerative capacity of MTJ tissue and potential for postsurgical scarring and reinjury necessitates complementary therapeutics that can enhance cellular interactions, restore mechanical properties, and support tissue rehabilitation. This review explores various approaches to engineer the MTJ utilizing biomaterial scaffolds and cellularized materials that mimic structure and function. While biomimetic materials show promise, challenges remain due to the interface’s complexity and differing patient- and location-specific structure–function characteristics, necessitating further research to address these gaps. This review also highlights the importance of studying MTJ injuries in women’s health and craniofacial reconstruction. Furthermore, engineered MTJ models provide versatile platforms for investigating trauma and degeneration, thus offering potential for advancing research across multiple fields, shedding light on interactions at tissue interfaces, and shaping the future of MTJ rehabilitation.

  3. Undergraduate research has emerged as a high-impact approach that can be used to enhance student engagement and to enrich student learning experiences. It is observed in the literature that undergraduate research can have an impact on student retention, and possibly attract women and ethnic minorities to science-related disciplines while playing an important role in the determination of career paths for participating students. While there are multiple studies on the impact of undergraduate research in social sciences and sciences, there is limited literature in the engineering disciplines. The limited volume of literature may be attributed to multiple reasons such as a significant emphasis on mathematics and science in the first two years of engineering curriculum, a strict sequential degree path, and a lack of flexibility in the program requirements. Engineering students often report difficulty in relating the theoretical content of the first few semesters to actual engineering applications. This study proposes the introduction of undergraduate research as a possible means of overcoming these student perceptions by introducing students to well-defined research projects at an early stage of their undergraduate degree program. The primary focus of this study is to understand student perceptions about the efficacy of undergraduate research in the engineering and engineering technology disciplines. Survey results from twenty six students involved in undergraduate research as part of the requirements for a scholarship program are presented and evaluated. Subjective evaluations from a few faculty members involved in mentoring some of these undergraduate researchers are also discussed. Although both students and faculty mentors agree that undergraduate research can be a highly valuable experience, it is commonly acknowledged that there are quite a few factors that are crucial in making the experience meaningful.

  4. Extensive damage to skeletal muscle tissue due to volumetric muscle loss (VML) is beyond the inherent regenerative capacity of the body, and results in permanent functional debilitation. Current clinical treatments fail to fully restore native muscle function. Recently, cell-based therapies have emerged as a promising approach to promote skeletal muscle regeneration following injury and/or disease. Stem cell populations, such as muscle stem cells, mesenchymal stem cells and induced pluripotent stem cells (iPSCs), have shown a promising capacity for muscle differentiation. Support cells, such as endothelial cells, nerve cells or immune cells, play a pivotal role in providing paracrine signaling cues for myogenesis, along with modulating the processes of inflammation, angiogenesis and innervation. The efficacy of cell therapies relies on the provision of instructive microenvironmental cues and appropriate intercellular interactions. This review describes the recent developments of cell-based therapies for the treatment of VML, with a focus on preclinical testing and future trends in the field.

  5. Cardiovascular diseases, including myocardial infarction (MI), persist as the leading cause of mortality and morbidity worldwide. The limited regenerative capacity of the myocardium presents significant challenges specifically for the treatment of MI and, subsequently, heart failure (HF). Traditional therapeutic approaches mainly rely on limiting the induced damage or the stress on the remaining viable myocardium through pharmacological regulation of remodeling mechanisms, rather than replacement or regeneration of the injured tissue. The emerging alternative regenerative medicine-based approaches have focused on restoring the damaged myocardial tissue with newly engineered functional and bioinspired tissue units. Cardiac regenerative medicine approaches can be broadly categorized into three groups: cell-based therapies, scaffold-based cardiac tissue engineering, and scaffold-free cardiac tissue engineering. Despite significant advancements, however, the clinical translation of these approaches has been critically hindered by two key obstacles for successful structural and functional replacement of the damaged myocardium, namely: poor engraftment of engineered tissue into the damaged cardiac muscle and weak electromechanical coupling of transplanted cells with the native tissue. To that end, the integration of micro- and nanoscale technologies along with recent advancements in stem cell technologies have opened new avenues for engineering of structurally mature and highly functional scaffold-based (SB-CMTs) and scaffold-free cardiac microtissues (SF-CMTs) with enhanced cellular organization and electromechanical coupling for the treatment of MI and HF. In this review article, we will present the state-of-the-art approaches and recent advancements in the engineering of SF-CMTs for myocardial repair.
