Matthew Brovold, MCB Track

November 2015 – October 2018
Mentor:  S. Soker, PhD
Focus:  Fibrotic Diseases of the Fetal Liver and Their Effect on Organogenesis

Matthew received his Bachelor’s degree in Genetics, Molecular and Cellular Biology in 2011 and worked as a Research Technician in 2012 before joining Dr. Shay Soker’s research group in 2013. His research is focused on development of a 3-D in vitro model of developmental diseases of the liver where fibrosis is prevalent. This study specifically focuses on biliary function and tubulogenesis, which may be affected when introduced into a fibrotic environment. The impact of fetal liver fibrosis on the development of the liver is a unique field of study into the rare, but devastating congenital liver disorders such as Biliary Atresia. Successful generation of this model will give insight into the effects of abnormal regulation of pathways critical for normal organogenesis. Matthew has taken a leadership role in the design a unique system that allows for the formation of biliary duct like structures that also allows for the analysis of cell-cell interactions with hepatic stellate cells, and of biliary transport functionality. He has also conducted a variety of experiments that show its utility of the model for use as a drug screening platform, which has the potential for use in adult liver fibrosis. Matthew has also incorporated a distinctive use of classic molecular analysis techniques along with more cutting edge techniques of image quantification through the use of open source software and custom designed MATLAB code.This training has also allowed for him to become an effective collaborator utilizing similar methodologies in the study of colorectal cancer metastasis and of the complex field of hepatic stellate cell activation and function.  

Matthew defended December 2019. Upon applying to and interviewing for several postdoctoral and faculty position with goal to continue his academic research in the field of developmental liver biology and to become more deeply involved in clinical developments for treatment of fibrosis he accepted a position at Wake Forest at Postdoctoral Research Fellow. 

Renata Magalhaes, MD, IPP Track

November 2016 – August 2018
Mentors:  K. Williams, DVM and A. Atala, MD
Focus:  Bioengineering Uterine Tissue in a Rabbit Model

Renata joined as a 3rd year Integrative Physiology and Pharmacology graduate student. Renata received her medical degree from the Pontificia Universidade Catolica de Sao Paulo, Brazil in 2002 and successfully completed her residency in Obstetrics, Gynecology, and fellowship in Minimally Invasive Surgery in 2006 at the Faculdade de Medicina do ABC, Brazil. Renata has been working on bioengineering uterine tissue in a rabbit model. In this study, she developed an engineered uterine tissue seeding ex vivo expanded autologous primary uterine cells into a polymer-based biodegradable scaffold that is tailor-made to replace a sub-total excised uterine horn. The preliminary results showed a successful in vivo time-course regeneration of uterine tissue within the constructs. Six months after cell-seeded construct implantation, the neo-uterine tissue showed organized tissue structures within the endometrium and myometrium compartments in which expression of specific markers for epithelial, stromal, smooth muscle, and endothelial cells was comparable to normal tissue. 

The ultimate goal of this project is to test the functionality of the bioengineered uterine tissue regarding reproductive outcomes. A new cohort of animals was naturally mated with fertile males six months after scaffold implantation and the pregnancy rates were 71.5% in the cell-seeded group, 50% in the polymer-only group, and 14.3 % in the injury-only group compared to 100% in the control group. The fetuses implanted within the engineered uterus had comparable size and weight with those implanted in the native uterine tissue at birth. These results suggest that a bioengineered uterine tissue supports viable pregnancy to term in rabbits. Successful completion of this project can potentially provide evidence for a RM-based approach for uterine factor infertility, as well as bring an important insight for bioengineering other organs with complex structure and function.

Renata defended her thesis May 2019. She is committed to staying closely involved in medical research and translational RM projects pertaining to the female reproductive system with ultimate interest in academic career. She is currently a Clinical Research Program Officer in Female Pelvic Health at Wake Forest Baptist Health and Wake Forest School of Medicine.

Kevin Enck, BME Track

September 1, 2017 to 2019)
Mentor:  E. Opara, PhD
Focus:  Next Generation Bioartificial Pancreas

Kevin joined as a 2nd year Biomedical Engineering graduate student at the VT-WF-SBES program. He received his BS in Biomedical Engineering from the University at Buffalo in 2014 and his MS from VT-WF in 2016.  Kevin has been working on engineering a new generation, bioartificial pancreas. The goal of this project is to develop a new generation bioartificial pancreas utilizing a current model of encapsulation of islets with alginate, but also incorporating the innovative properties of decellularized tissue to increase the viability and functionality of islets. In vitro experiments will be performed initially to optimize the properties of the ECM powder such as concentration. Next, in vivo experiments in immune-compromised T1D rats will be done to assess if the islets can function properly and maintain normoglycemia for an extended period of time. For all experiments, islet functionality and viability will be measured using insulin ELISAs, live-dead immunofluorescent assays, histological assessment, dithizone staining, along with other tests.

Kevin defended in summer 2019. His goals were open to all sectors, but with a growing interest in the government scientist and industry science positions coupled with a commitment to remaining in biomedical research field and desire to keep doing RM work at the bench in a translational capacity. In July 2019 he accepted a position as Product Development Scientist at Stallergenes Greer, a global healthcare company specializing in the development of allergy immunotherapy products and services. With Stallergenes aspiration to “change the treatment paradigm of allergy therapies by delivering curative medicines, technologies and tools for patients”, Kevin brought a specific skill and mindset where is he now currently designing diagnostic assays for second generation immunotherapy.

Andrea Mazzocchi, BME Track

January 2018 to current
Mentor: A. Skardal & S. Soker, PhDs
Focus: In vitro microenvironment fabrication for modeling of physiology and disease

Andrea joined as a 2nd year Biomedical Engineering graduate student in the VT-WF-SBES program. She received her BS in Biomedical Engineering from Rochester Institute of Technology in 2016. Andrea has been working on topics such as bioprinting, tumor organoids for precision medicine, and customized liver biomatrices.
