R01 Award

Title: "Extracellular Matrix Regulation of Inflammatory Signaling in Tendon"

Funding:  $1,750,000

Duration: 5 years


The work proposed in this award aims to engineer a novel tendon-specific microphysiological system to understand how the loss of extracellular matrix stiffness increases inflammatory signaling in tendinopathy. Knowledge gained from these studies will inform the development of therapeutic targets to treat tendon disease. Our scientific partners are Dr. Brendon Baker in Biomedical Engineering and Dr. Claudia Loebel in Materials Science & Engineering. Dr. Paul Talusan and the Foot and Ankle service continue to be critical supporters of our work by providing patient-derived tissue samples across a spectrum of tendinopathies.

Congratulations, Emma Snyder-White

UROP AWARDS

Congratulations, Allison Risha!

Blue Ribbon Certificate 

Allison's Project: Due to their cellular morphology, tendons are unable to be seen in 3D via microCT imaging. This prevents us from a deeper study of tendons after injury and makes it difficult to compare tendon shape after a change in genotype. Past research shows that eosin was found to be an effective contrast enhancing agent to help improve the visibility of previously radiopaque structures when scanned via MicroCT. Allison's project consisted of creating a protocol to stain tendons in an eosin based dye and scan them in the MicroCT with the goal of improving 3D visibility of the tendon, specifically focused on being able to visualize the tendon at the cellular level. After staining, we were able to clearly see the tendon in 3D. Although the cells of the tendon were a bit too small to be seen, the ability to see the overall shape and size of the tendon will greatly enhance our study of the structure.  

The UROP symposium celebrates the partnerships created between students and research mentors and serves as a conference where students present their research projects and learn about the research their fellow UROP students have worked on throughout the program. Congratulations to Allison on achieving this award and kudos to Nicole on her mentorship!

Congratulations, Zaynah Saraya!

Two Blue Ribbon Certificates! 

Zaynah's Project:  Approximately 15 million fractures occur yearly in the United States, however around 10% of these fractures will result in a nonunion or malunion, meaning that they will not heal without surgical intervention. Many factors can contribute to impaired fracture healing including age, ischemia, smoking, chronic inflammation, infection, and polytrauma injuries. This presents a pressing need to understand the mechanisms that underlie impaired healing and understand the processes that facilitate fracture healing under healthy and  impaired conditions. Our studies specifically focus on modulating gene expression and understanding how this impacts fracture callus formation and mineralization. Within the lab we have shown that global deletion of the gene thrombospondin 1 (TSP1) leads to impaired fracture callus formation and healing, however the exact mechanisms are not well defined. TSP1 has been shown to have roles involved in regulation of blood vessel growth, inflation, and fibrosis. Our study seeks to assess how different cell populations expression of TSP1 leads to this impaired healing. Our lab has shown that TSP1 is highly expressed by the immune population during fracture callus formation. Thus, we hypothesize that inhibition of TSP1 in the immune population will have the same effect of impaired healing as a global deletion. We can assess this through analysis of cartilage and bone formation using Safranin-O/Fast green staining. Through immunofluorescent staining we can also interrogate differences in blood vessel growth.

Research Highlight

Yadav Wagley, 

Research Investigator of Orthopaedic Surgery 

Yadav Wagley

Research Investigator, Orthopaedic Surgery

Yadav Wagley, PhD, has been with the department since 2017. Dr. Wagley is an active member of the American Society for Bone and Mineral Research (ASBMR) and Orthopaedic Research Society (ORS), which are his primary academic communities. 

Research Interest: 

Dr. Wagley is an Early-Stage Investigator with a passion for uncovering signaling crosstalk and functional role of novel genes during mesenchymal stem/progenitor cell (MSC) differentiation into osteoblasts, chondrocytes, and adipocytes. He has been at the Orthopaedic Research Laboratories (ORL) since 2017 under the direct supervision of Dr. Kurt D. Hankenson. Working alongside Dr. Hankenson, he has successfully developed and characterized various in vitro and in vivo research models for mechanistic and translational interventions for enhanced bone regeneration. Dr. Wagley’s future research program focuses on functionalizing novel bone mass effector genes regulated by non-coding genomic variants. He collaborates with geneticists and bio-informaticists from Children’s Hospital of Philadelphia to utilize assay for transposase-accessible chromatin, capture-C, and cutting-edge genome editing technologies to intersect bone mineral density (BMD) genome-wide association study (GWAS) data in differentiating human osteoblasts to implicate novel BMD effector genes. The functional requirement of putative genes is established using gene silencing experiments in differentiating hMSC and human fetal osteoblasts. An additional goal of his research is to understand the genetic regulatory mechanism of these novel effector genes during progenitor cell differentiation and understand the overall molecular changes elicited in their absence both in vitro and in vivo. The ultimate goal of his research program is to advocate the therapeutic targeting of these genes for bone and cartilage regeneration through collaboration with other principal investigators within the ORL. 

Examples of some of Dr. Wagley’s active research projects include:

1.      EPDR1 specification of bone turnover by inflammatory crosstalk within the bone microenvironment

2.      Osteochondral fate specification of mesenchymal progenitor cells by microRNA-199a-5p modulation

3.      Elucidating the integration of bone morphogenetic protein and Notch signaling pathway for enhanced human osteoblast differentiation
