NCBI Bookshelf. Cham CH : Springer; Authors Norbert Claude Gorin. Parallel attempts at using fetal liver cells at that time have remained unsuccessful. There remain however several situations where and when a marrow harvest can still be of interest or even is highly recommended. This chapter indicates the principal indications of BM transplantation, compares schematically the advantages of BM versus PB, and details the technique of BM harvesting.

Several studies, including prospective randomized studies, have shown in general with BM when compared to PB slower engraftment but lower incidence and lower severity of acute and chronic GVHD with in the end similar disease free and overall survivals Schmitz et al. Also, the quality of life has not been carefully analyzed Sun et al. Table The clinical significance of different HSC sources primed marrow, mobilized blood, and steady-state marrow in auto- and allo-HSCT was reviewed in Elfenbein and Sackstein Marrow is collected from the posterior superior iliac crests, usually under general anesthesia, although few teams have used sedation or locoregional anesthesia Fig.

Marrow is aspirated with bone needles with multiple holes all around, which makes collection easier and the procedure more rapid. The collection bag contains ACD anticoagulant solution and the syringes are rinsed with heparin 5. However, it should be kept in mind that old studies in the early development of BMT have indicated better results both in terms of engraftment but also decrease in NRM and RI and better outcome, with higher marrow doses Gorin et al.

Transplant in remission of acute leukemia with a high dose of marrow cells was associated with the best outcome in both children and adults. If the targeted goal cannot be achieved, additional collection can be made from the anterior iliac crests, although it is time consuming and potentially more harmful for the patient or the donor, who must be turned over with all sterile fields to be reinstalled.

Depending on the volume collected, three attitudes regarding transfusion during marrow collection may be followed: no transfusion and liquid replacement is the first option for many teams.

In rare circumstances allo-transfusion remains possible; usually two packs of concentrated red cells are enough. Another option to consider to increase the stem cell dose to infuse when marrow collection has been insufficiently productive is the addition of PBSC. Two examples of this dilemma are summarized below: 1. The NMDP analyzed in , volunteers who donated unrelated marrow from October in 42 centers Stroncek et al. Apnea during anesthesia occurred in one donor. The recommendation of this study was the duration of the collection procedure and probably the duration of anesthesia, and therefore the volume of marrow collected should be kept to a minimum, but this conclusion is to be weighed against the wish to collect stem cell doses as high as possible to ensure fast engraftment and improve outcome.

Cryopreservation and storage of a marrow in view of an allo-HSCT is possible. However, it should be kept in mind that any cryopreservation procedure, would it seem perfect, results in some measurable CFU-GM, BFU-E and many less measurable immune functions, etc. Therefore, it should be reserved to special situations when, for instance, the donor cannot be available at the very time of the transplantation procedure.

As a rule, fresh marrow is preferable to frozen marrow. The major indicator for successful BM collection is the dose collected, as discussed above, i. It is very usual to have a blood count done at the mid time of the collection to ensure proper richness.

For cryopreserved marrow, some teams routinely cryopreserve small samples in minibags or ampoules, enabling viability testing before thawing the graft usually an autograft. However, and importantly, a technical bias has been observed with ampoules since differences in cooling rates prevent ampoules from being a reliable index of HSC cryopreservation in large volumes Douay et al.

More pertinent testing consists in the evaluation of CFU-GM which represents in this setting the most reliable functional viability indicator Douay et al.

However, BM transplantation has not disappeared and is likely to persist in some limited situations and indications. Further studies may revisit and increase the choice of marrow as stem cell source. Turn recording back on. National Center for Biotechnology Information , U.

Cryopreservation is the rule for auto-BMT, while it should be avoided and used only in rare specific conditions for allogeneic transplantation. BM is mandatory in children and patients with aplastic anemias. It is presently favored by some teams in the context of haploidentical transplantation. Long-term cryopreservation of human stem cells.
