what you see is a human stem cell. stem cells and their usage will be the 21st centuries medical miracles. recently Stanford released some results from a stem cell trial they performed and it has set the world of brain injury/damage on fire!the trial was quite small and the results so impressive they're doing another larger trial, I signed up as a Guinea pig. this news might have kicked open a door similar to the impact by the discovery of Penicillin had decades ago
the term they use is "expand" and many biotechs have become excellent at it. so a single donation of cells can now be expanded with the same potency and quality to millions of doses
