The second part of the project and content of this report has been conducted at the Technical University of Dresden (TUD). During this reporting period, my work has led to groundbreaking discoveries that challenge the traditional understanding of oxygen’s role in bone repair. We have introduced a new paradigm advocating for hypoxia-promoting therapies to enhance bone healing, with significant clinical potential for accelerating fracture recovery and addressing complications such as non-unions. These findings were formalized in a provisional patent filed with the University of Pennsylvania titled "Devices and Methods for Bone Fracture Healing and Segmental Defect Healing," which involves novel orthopedic devices and methods that modulate oxygen levels at fracture sites.
To disseminate these important findings, I intensified engagement with the scientific community through conferences, seminars, and networking opportunities. Additionally, a shift from in vitro approaches to in-depth genomics data analysis was necessary to explore the underlying mechanisms of these discoveries. I received specialized training in genomics data analysis, including the use of the R toolkit (Seurat) and gene set enrichment analysis (GSEA), enabling me to extract key insights from our datasets.
Key achievements include:
1. Analysis of cell population changes 3 days post-fracture.
2. Evidence supporting the role of erythroid progenitors in fracture repair.
3. Identification of mechanisms governing intracellular oxygen binding.
These findings provide valuable contributions to the field of bone fracture research.
