Research Overview |
In the last few years, we have addressed the characterization of somatic stem cells, including Mesenchymal Stem Cells (MSC) and Hematopoietic Stem Cells (HSC) from different sources, to study the molecular basis of their specific biological characteristics, as well as to provide evidence for their distribution and in vivo role. In fact, we have helped to establish the concept that MSCs occupy a perivascular niche throughout the body, closely resembling pericytes, providing a cell repository for tissue repair and also playing important roles in the maintenance of peripheral immunehomeostasis. In that sense, we provided evidence of a new immunomodulatory mechanism exerted by MSC in response to inflammatory stimuli derived from activated T lymphocytes (Saldanha-Araujo et.al. 2011). Moreover, our results points to a role of MSCs in the modulation of NF-kB signaling in activated T lymphocytes, switching from a canonical pro-inflammatory to a non-canonical immunoregulatory role (Saldanha-Araujo et.al. 2011b). We have also provided evidence for the role of non-canonical NF-kB signaling in the characteristic molecular features of HSC derived from Umbilical Cord Blood (UCB), as compared to Bone Marrow (BM). |
