Professional Interests

Our laboratory is interested in understanding how hematopoietic stem cells (HSCs) and mature blood cells traffic in vivo. We have uncovered a key role for the nervous system in regulating HSC trafficking, and are evaluating its role in the inflammatory response in diseases such as sickle cell disease. In addition, we are also exploring whether the traffic paradigms uncovered for healthy stem cells applies to cancer cell migration and metastasis.

Molecular and cellular constituents of the stem cell niche. HSCs continuously traffic from the bone marrow to the blood compartment (and vice-versa) under homeostasis. Recent studies have focused on the role of the nervous system in the regulation of the HSC niche in the bone marrow. This effort is based on our observations suggesting a critical function of adrenergic signals emerging from the sympathetic nervous system (SNS) in HSC egress. While investigating further the mechanisms by which HSCs were mobilized, we have found that exposure to constant light significantly reduced mobilization efficiency following the administration of the hematopoietic cytokine G-CSF. G-CSF is the most commonly used HSC mobilizer in the clinic to harvest stem cells for transplantation. This finding prompted us to assess how HSC are released from the bone marrow under steady-state conditions. We have described the phenomenon and its mechanisms. These studies revealed that stromal cells in the bone marrow are subjected to circadian adrenergic signals transmitted by the beta3 adrenergic receptor that lead to the degradation of the transcription factor Sp1 and diurnal changes in the expression of the chemokine Cxcl12. Recent investigations are focused on the identification and regulation of the stromal target for the SNS. These studies have led to the identification of a Nestin+ mesenchymal stem cell as a candidate niche cell required for HSC maintenance in the bone marrow. We have developed a novel imaging approach to assess native HSC in the bone marrow using whole-mount confocal analyses which have revealed distinct vascular niches, arteriolar and sinusoidal, that are conferred by subsets of Nestin+ cells. Ongoing studies are dissecting further the stromal subsets that form the bone marrow microenvironment.

Mechanisms of sickle cell vaso-occlusion. This project emerged from our intravital microscopy observations suggesting that sickle cell vaso-occlusion was mediated by the direct interaction between sickle erythrocytes and adherent leukocytes in small venules. Further analyses using novel high-speed multichannel fluorescence microscopy techniques have revealed that E-selectin-mediated activating signals emanating from the inflamed endothelium led to the activation of specific microdomains on the leading edge of adherent neutrophils, which then induce intravascular heterotypic interactions between erythrocytes or platelets with adherent leukocytes. Ongoing studies dissect further the molecular basis of this phenomenon.

Role of the nervous system in cancer. We are exploring the role of the autonomic nervous system in cancer formation and metastasis using xenogeneic and transgenic models of prostate cancer. These studies have led to the indeitification of novel functions for the sympathetic (adrenergic) and parasympathetic (cholinergic) nervous system in the initiation and metastasis, respectively, of prostate cancer. Further studies will analyze in more detail the mechanisms and to obtain new insight on the cellular and molecular cues that regulate the tumour microenvironment and allow cancer cells to spread.
