Day 15: Seeding cells

Seeding cells is the process of taking the cells that have been happily growing in their flask full of everything they could ever need, and transferring them into a vessel that is much easier for experiments! This more useful container for cell experiments are know as 6-well and 96-well plates, basically a plastic tray containing 6 small or 96 tiny flat bottomed cylinders, which looks a little like this: 

The cells were 'seeded' onto the plate, with a supply of culture medium, and left to grow overnight in an incubator. Tomorrow morning, hopefully all the cells will have stuck (adhered) to the base of the plates and will look under the microscope like the 'eye' shape instead of the perfectly round shape you see when they are lifted off the base with Trypsin so they can be transferred.
