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 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 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).
We are currently starting to address the molecular mechanisms by which MSC become activated to exert their immunomodulatory properties, upon treatment with pro-inflammatory stimuli (a mechanism generally referred as MSC “licensing” or “conditioning”). Finally, we are currently using synthetic pre-miRs and anti-miRs to explore the roles of microRNAs in the regulation of distinct stem cell characteristics (including pluripotency, differentiation, self-renewal, among others), and to identify functionally-relevant microRNA targets (through coupled microarray profiling).
