The stem cells are collected preferably in advance of the treatment day, whether a donor is used or the patient’s own cells. Patient is first be given high dose chemotherapy and/or radiotherapy called conditioning as a part of transplant process to knocked out the diseased or damaged patients bone marrow, therefore making space for new stem cells. These procedure weakens the immune system of the patient, and thus requires to be hospitalised in an isolated space with special facilities including HEPA filters to reduce the risk of life threatening infections.
The donor stem cells are then transplanted through infusion by using a central venous catheter that allows the cells to enter the bloodstream and reach the bone marrow. Once the transplant has been performed successfully, great care has to be taken to prevent infections and complications.

Collection of stem cells requires preparation including injections to mobilise stem cells from bone marrow to peripheral blood. During this time patient may experience pain, chills, fever, or flu-like symptoms. Collection of stem cells are usually done using central venous catheter that includes risk of bleeding and pain. The complications related to conditioning are same as usual of high dose chemotherapy and includes vomiting, nausea, loose motion, mucositis, risk of infection and bleeding, or hair loss. The stem cell infusion includes risk of infusion reaction, vomiting, chills or rigors, hives or chest pain. Physical conditions like nausea, vomiting, diarrhea, mouth sores, weakness or mental conditions like emotional distress and temporary mental confusion may also manifest. Bone marrow transplant process involves life threatening risk as well incluuding sepsis, bleeding in vitals organs and may rrequire ICU care and risk of death.
