It may be necessary to perform bone marrow collection as part of an experimental protocol. For example the isolation of hematopoietic stem cells may require this methodology. It is also possible to administer therapeutic agents, such as fluids, and test substances into the bone marrow. Absorption from the bone marrow is essentially equivalent to performing iv administration.
