Abstract: The described invention provides an ex vivo dynamic multiple myeloma cancer niche contained in a pumpless perfusion culture device. The dynamic multiple myeloma cancer niche includes (a) a three-dimensional tissue construct containing a dynamic ex vivo bone marrow niche, which contains a mineralized bone-like tissue containing viable osteoblasts self-organized into cohesive multiple cell layers and an extracellular matrix secreted by the viable adherent osteoblasts; and a microenvironment dynamically perfused by nutrients and dissolved gas molecules; and (b) human myeloma cells seeded from a biospecimen composition comprising mononuclear cells and the multiple myeloma cells. The human myeloma cells are in contact with osteoblasts of the bone marrow niche, and the viability of the human myeloma cells is maintained by the multiple myeloma cancer niche.
