## Abstract

ABSTRACT
Bone marrow represents a rich source of diverse stem, progenitor and other cells of clinical and research interest
including hematopoietic stem cells (HSC) and mesenchymal stem cells (MSC), dendritic cells, T-cells, natural
killer (NK) cells, B-cells and others. Currently, these cells are only recovered from living donors through bone
marrow aspiration or peripheral blood mobilization. Ossium Health is developing the first clinical and research
bank of bone marrow derived cells from deceased organ and tissue donors. While the concept of utilizing this
resource for bone marrow cells was first described over 60 years ago, the ability to recover viable material
efficiently and the infrastructure necessary to achieve this at even a modest scale simply has not existed. Ossium
Health has overcome this by establishing a robust ecosystem comprised of a world-class tissue processor (and
Phase III partner), major organ procurement agencies and innovation to, for the first time, allow recovery and
banking of this plentiful source of potentially life-saving cells. However, for this bank to reach its full potential,
further efficiencies must be advanced and implemented. This Phase II study aims to develop “smart baking”
innovations by optimizing methods of cryopreserving intact marrow in situ within whole bones to allow time for
infectious disease, sterility and HLA testing prior to investing in fully processing donor bones to isolate cellular
components. This innovative work will also provide early guidance towards cryopreservation of more complex
tissues such as vascular composite allografts (VCA). The resulting technology from this study may increase
efficiency by as much as 80% - drastically reducing cost and allowing more readily available and less expensive
clinical grade and high-quality research material to be available to meet the growing demands of gene therapy,
tissue engineering and basic science investigation.
