September 2022 in “Medical Mycology” Three different methods were compared for creating Titan cells, a type of fungus cell. The OZ method made the most cells initially, but the number dropped quickly. The EB method also made a lot of cells, but the number also dropped. The AA method made fewer cells, but the number stayed steady. The methods also affected which genes were active in the cells.
Regulatory T cells enhance bone formation by influencing cell mechanics.
