For more than two decades, the U.S. Government has made purposeful investments to develop medical countermeasures that can diagnose, mitigate, and treat injuries in the event of a radiological or nuclear emergency. These programs rely on strong public-private partnerships, and we’re proud to be part of this effort to ensure the nation is prepared should the unthinkable occur.

Recognizing that bone marrow is among the most sensitive and essential systems affected by radiation exposure, the Government made key investments in therapies that address myeloablation of the bone marrow following exposure to high doses of irradiation.

These critical medical countermeasures, including Ossium’s bone marrow bank, are described in a recently published review article:

“Innovative sourcing and cryopreservation of bone marrow from deceased organ donors (alternative hematopoietic progenitor cells (HPC) grafts) by Ossium Health has been explored as a means of obtaining large quantities of banked HPCs for use in myeloablated patients. These cell populations have been well-characterized, and their functionality has been found to be equivalent to live bone marrow donations.” (DiCarlo et al., 2025)

Advances in cellular therapy are creating new possibilities for patients with blood cancers and expanding access to bone marrow transplantation beyond traditional donor sources. Franciscan Health is at the forefront of this progress, offering innovative transplant approaches, including the use of bone marrow recovered from deceased organ donors. This on-demand graft source helps reduce delays, expand donor availability, and ensure more patients have timely access to potentially lifesaving transplants.

A recent editorial in the American Society of Clinical Oncology Journal of Clinical Oncology highlights an urgent truth for blood cancer patients: how quickly a bone marrow transplant can be performed is as critical as HLA matching.

Referencing results from the BMT CTN 1702 study, author Alessandro Rambaldi, MD emphasizes that for high-risk blood cancers like acute leukemia, faster access to a donor can make the difference between cure and relapse:

“When the risk of relapse is high, as in the case of acute leukemia patients, the shorter the time to transplant, the better the outcome. This seems particularly important, for urgent cases for whom a timeline of 6 weeks or less from unrelated search initiation to graft infusion should be considered ideal. Accordingly, disease biology, patient-related variables, and keeping the time to transplant as short as possible are more important than waiting for a better HLA-matched donor.”

At Ossium Health, we’re making that rapid access a reality. Our cryopreserved bone marrow banking platform ensures donors are available on demand, enabling bone marrow transplants to be performed within 72 hours of the initial donor search.
