Image of the Day: Smell You Later

Adult olfactory stem cells can be used to grow a smattering of cells important for smell, including scent-sniffing neurons and structurally supportive sustentacular cells.

Deconstructing Olfactory Stem Cell Trajectories at Single-Cell Resolution

"...provides a model for deconstructing similar hierarchies in other stem cell niches."

THIS MODEL DETAILS HOW CHEMICAL ECOLOGY DRIVES ADAPTIVE EVOLUTION VIA: (1) ecological niche construction, (2) social niche construction, (3) neurogenic niche construction, and (4) socio-cognitive niche construction. This model exemplifies the epigenetic effects of olfactory/pheromonal conditioning, which alters genetically predisposed, nutrient-dependent, hormone-driven mammalian behavior and choices for pheromones that control reproduction via their effects on luteinizing hormone (LH) and systems biology.

My model compliments the representations of biophysically constrained niche construction in Feedback loops link odor and pheromone signaling with reproduction

The virus-driven degradation of messenger RNA has since been linked from mutations to all pathology via a game that presents facts about cell biology to anyone age 10 or older.
