| Outline of Research at the Start |
The scientific significance of this research is to perform genome-wide transcriptomic analysis using the RNA-seq approach which will allow us to profile the regulated biological pathways during TB reactivation.
|
| Outline of Annual Research Achievements |
To establish the human cell-based in-vitro granuloma model, human donated PBMCs were purchased from the company (Cosmo Bio) and stored in the liquid nitrogen until use. Other necessary reagents for the optimal growth of PBMCs to form granulomas, such as 3D culture gel, human serum for culture medium, and extracellular matrices, enable to mimic in-vivo environments for 3D cell culture applications were all obtained. Additionally, to develop a co-culture system for the dynamic interaction of the formulated granuloma and other immune cells in PBMCs, permeable Transwell Inserts were ordered. Prolonged survivals of granulomas will be used as an indicator for evaluating the feasibility of this co-culture system.
The research was discontinued when the principal investigator was unable to continue the research beyond one year.
