Learning about ‘organoids’

The Tissue culture Lab is a designated space where, as the name implies, cells are cultured for distribution to researchers. It contains centrifuges, various types of incubators, microscopes, computers and a fume cupboard, to name but a few of the required items.

Mitchell & I donned our gowns and put on rubber gloves. During this session we frequently disinfected our gloves by spraying with alcohol.  A single virus can wipe out a whole set of cultures so obviously we erred on the side of caution!

There are many stages in the culture of organoids and the images below are representational of some of these stages:

Day 1, Embryonic stem cells are captured

This shows samples of the cells at the beginning of the culture process. They are still flat.

The spun cells have begun to separate and and the process of disaggregation, carried out be hand, seoarates them further into other containers.
Day 6, The spun cells have begun to separate and and the process of disaggregation, carried out by hand, separates them further into other containers.

The cells are separated and placed in the growth medium in the incubator.

Day 21, sensory neuronal orgnanoids
Day 21, sensory neuronal orgnanoids

The various stages of development produce spherical organoids, similar to the illustration above.  The type of organoid depends on the content of the growth medium. Apparently nascent spinal column cells can be seen here.
