What are the first signs that a blood stem cell transplant has been a success?

After two to four weeks, an increase in the patient’s white corpuscle count offers an initial indication that the new blood stem cells are doing their job and creating healthy blood cells. If the corpuscles continue steadily increasing, the outlook for the patient improves. The success of the therapy is affected by a range of factors, such as the type of basic illness, the stage at which it was diagnosed and treated with a transplant, the age and general fitness of the patient, possible accompanying illnesses, type of conditioning, and the closeness of the match between patient and donor tissue characteristics.
