Flow cytometry is a technology that allows high throughput analysis of the characteristics of cell populations by optically and rapidly measuring the morphological characteristics and fluorescent signals of the cells suspended in a narrow stream of fluid in equipment (flow cytometer). In addition, the equipment with a cell sorter can collect a certain type of cells from a heterogeneous population by charging droplets containing such cells identified by the optical data and attracting them by an electrostatic deflector. In this post town in this drawing, 'Positive' inn on the right and 'Negative' inn on the left are finding and attracting potential customers from passersby. They just look like a cell sorter. There is seen above them a cluster of clouds that resembles flow cytometric data.
Kiyomizu-dera temple in Kyoto is famous for its 12-meter high Butai ('stage'). In Edo era, there was a popular superstition that if one survived a jump from the Butai, one's wish would come true. In this drawing, one woman holding an umbrella as a parachute has jumped from the Butai over the fully blossomed cherry trees. In the Drosophila wing imaginal discs drawn on her kimono, the spatial expression patterns of genes involved in pattern formation can be discerned. May the Drosophila wing imaginal discs differentiate into wings before she crashes to the ground. Drosophila adults have gathered from nowhere as if they escorted her in a cherry blossom snowstorm.
