A Multi-Niche Culture Method for Mimicking Human Bone Marrow
Bone marrow (BM) is complex, highly cellular tissue that consists of three distinct microenvironments: the endosteal niche, the central marrow, and the perivascular niche. Hematopoietic stem cells (HSCs) are located in the BM and interact with a number of stromal cells (e.g. mesenchymal stem cells (MSCs), osteoblasts, endothelial cells, adipocytes). These interactions direct HSCs toward self-renewal, proliferation, migration, and differentiation in healthy individuals to populate and maintain the hematopoietic system. Currently, our understanding of the hematopoietic BM niche is limited to animal and ectopic bone marrow models; there is no method for studying the human BM microenvironment. This has led to uncertainty regarding the HSC niche and lack of understanding of the role of the BM microenvironment in disease, such as multiple myeloma, which evades therapy through microenvironment interactions. This proposal aims to establish a microfluidic culture method, a ‘bone marrow-on-a-chip’, that recapitulates the BM microenvironment. The developed method will be used to study (1) normal HSC migration, proliferation, and differentiation dynamics within BM; and (2) the role of the BM microenvironment in multiple myeloma survival and therapeutic evasion.
