Biography

Biography

Dr Paola Campagnolo is currently Lecturer of Molecular Cardiovascular Biology in the School of Biosciences and Medicine, Faculty of Health and Medical Sciences. Paola graduated in Biotechnology at the University of Padua, Italy. She then moved to Bristol to work under the supervision of Prof Paolo Madeddu at Bristol Heart Institute. In 2009, Paola completed her PhD in Cardiovascular Biology working on the isolation of a patient derived pro-angiogenic progenitor cell population. Next, Paola joined Prof Qingbo Xu's the BHF Centre of Excellence at King's College London as a BHF Research Associate to explore the use of stem cells for the repopulation of vascular grafts. In 2013, Paola joined Prof Molly Stevens' group at the Department of Materials at Imperial College London to undertake the study of novel bio- and nano- materials for cardiovascular tissue engineering.Paola has published extensively in top journals in the field of cardiovascular biology and material science with a total of over 646 citations.Paola is part of the editorial board of Editorial Board of Cardiovascular Biologics and Regenerative Medicine (specialty section of Frontiers in Cardiovascular Medicine), act as a reviewer for several journals, including PLoSONE and ATVB and is part of the reviewing board for the French National Agency of Research and the Italian Ministry of Health.

Finding a suitable cell source for endothelial cells (ECs) for
cardiovascular regeneration is a challenging issue for regenerative
medicine. In this paper, we describe a novel mechanism
regulating induced pluripotent stem cells (iPSC) differentiation
into ECs, with a particular focus on miRNAs and their targets.
We first established a protocol using collagen IV and VEGF to
drive the functional differentiation of iPSCs into ECs and compared
the miRNA signature of differentiated and undifferentiated
cells. Among the miRNAs overrepresented in differentiated
cells, we focused on microRNA-21 (miR-21) and studied its
role in iPSC differentiation. Overexpression of miR-21 in predifferentiated
iPSCs induced EC marker up-regulation and in
vitro and in vivo capillary formation; accordingly, inhibition of
miR-21 produced the opposite effects. Importantly, miR-21
overexpression increased TGF- 2 mRNA and secreted protein
level, consistent with the strong up-regulation of TGF- 2
during iPSC differentiation. Indeed, treatment of iPSCs with
TGF -2 induced EC marker expression and in vitro tube formation.
Inhibition of SMAD3, a downstream effector of TGF -2,
strongly decreased VE-cadherin expression. Furthermore,TGF -2
neutralization and knockdown inhibited miR-21-induced EC
marker expression. Finally, we confirmed the PTEN/Akt pathway
as a direct target of miR-21, and we showed that PTEN
knockdown is required for miR-21-mediated endothelial differentiation.
In conclusion, we elucidated a novel signaling pathway
that promotes the differentiation of iPSC into functional
ECs suitable for regenerative medicine applications.

The recent development of tissue engineering provides exciting new perspectives for the replacement of failing organs and the repair of damaged tissues. Perivascular cells, including vascular smooth muscle cells, pericytes and other tissue specific populations residing around blood vessels, have been isolated from many organs and are known to participate to the in situ repair process and angiogenesis. Their potential has been harnessed for cell therapy of numerous pathologies; however, in this Review we will discuss the potential of perivascular cells in the development of tissue engineering solutions for healthcare. We will examine their application in the engineering of vascular grafts, cardiac patches and bone substitutes as well as other tissue engineering applications and we will focus on their extensive use in the vascularization of engineered constructs. Additionally, we will discuss the emerging potential of human pericytes for the development of efficient, vascularized and non-immunogenic engineered constructs.

oxide nanostructures by a biocompatible antifouling
homopolymer,
ACS Applied Materials & Interfaces 9 (46) pp. 40059-40069 American Chemical Society
Iron oxide nanostructures have been widely developed for biomedical applications,
due to their magnetic properties and biocompatibility. In clinical application, the stabilization of
these nanostructures against aggregation and non-specific interactions is typically achieved using
weakly anchored polysaccharides, with better-defined and more strongly anchored synthetic
polymers not commercially adopted due to complexity of synthesis and use. Here, we show for
the first time stabilization and biocompatibilization of iron oxide nanoparticles by a synthetic
homopolymer with strong surface anchoring and a history of clinical use in other applications,
poly(2-methacryloyloxyethy phosphorylcholine) (poly(MPC)). For the commercially important
case of spherical particles, binding of poly(MPC) to iron oxide surfaces and highly effective
individualization of magnetite nanoparticles (20 nm) are demonstrated. Next-generation highaspect
ratio nanowires (both magnetite/maghemite and core-shell iron/iron oxide) are
furthermore stabilized by poly(MPC)-coating, with nanowire cytotoxicity at large concentrations
significantly reduced. The synthesis approach is exploited to incorporate functionality into the
poly(MPC) chain is demonstrated by random copolymerization with an alkyne-containing
monomer for click-chemistry. Taking these results together, poly(MPC) homopolymers and
random copolymers offer a significant improvement over current iron oxide nanoformulations,
combining straightforward synthesis, strong surface-anchoring and well-defined molecular
weight.
