When cells are grown outside of their source organism, they must be cultured under conditions that closely mimic their native in vivo environment.
Spheroidal cultures exhibit greater physiological relevance than 2D cell cultures, including improved cell viability, morphology, proliferation, differentiation, metabolic activity, migration, angiogenesis, and gene expression.
Advancements in microscopy over the last two decades have created a revolution in biology, allowing complex, dynamic processes to be recorded with high spatial and temporal resolution.
Viruses are basically a ball of genetic material surrounded by protective proteins that have one goal, often at odds with human health: self-reproduction.
