How well can we read the structure of the stem cells used for creating white blood cells? and what tools do we have to change this structure?

Most of the experts: on this HealthTap site are practicing physicians with expertise in clinical medicine. I, as a clinical internal medicine specialist, am not able to answer this question. Possibly there is someone on the site who has this expertise and can share it with you. Alternatively, you need to identify molecular genetics expertise elsewhere. Good luck and good wishes:)
