Regenerative medicine is a branch of translational research in tissue engineering and molecular biology which deals with the process of replacing, engineering or regenerating cells, tissues or organs to restore or establish normal function. At NANOTEC we aim to regenerate damaged tissues by combining cells from the body with highly porous biodegradable scaffolds, which act as templates for tissue regeneration. We also use powerful state of the art techniques to study the bone-tissue regeneration mechanism

Smart Materials for Regenerative Medicine

Current regenerative medicine strategies are mainly focused on the design of improved biomaterials that are non-immunogenic, biocompatible, and biodegradable, and can be functionalized with bioactive proteins and chemicals. Our research is based on alternative approach to produce biomaterials that mimic the extracellular matrix (ECM). For instance artificial biocompatible and biodegradable fibrous extracellular matrices are realized using a variety of natural and synthetic polymers in order to increase cell proliferation and cell adhesion. Another approach involves freeze-dried 3D porous collagen–chitosan scaffolds which are functionalized with protease-responsive capsules loaded with growth factors for guiding and controlling the release of selected bioactive agents that work in concert with the implants.

In association with Maastricht University (Prof. L. Moroni;, several biofabrication technologies are also being developed to create smart constructs and direct cell fate. The core activities of the group evolve around acquiring and implementing knowledge for biofabrication technologies based on the following research objectives: (i) develop biofabrication technologies based on additive manufacturing and spinning, and bottom-up methodologies; (ii) integrate neural and vascular cues on current tissue regeneration strategies; (iii) engineer the immune response of biomaterials and biomedical devices.


Another alternative emerging approach involves biomaterials produced by the cells themselves in response to a chemical stimulus. Indeed, we exploited living cells as factories to produce new, functional and intelligent fibrils for tissue engineering, through the aid of synthetic dyes which spontaneously penetrate the membrane of living cells.

Plasma processing of scaffolds for tissue engineering

Plasma processing of scaffolds for tissue engineering can be used mainly to: 1) functionalize the scaffold surface in order to improve, when necessary, its hydrophilic character (i.e. transport of metabolites and waste products through water); 2) produce graded chemical composition from the top to the scaffold’s core to enhance cell colonization of the whole scaffold; 3) “decorate” the scaffold’s surface with biomimetic coatings containing proteins or ceramics (i.e. hydroxyapatite or magnesium) that resembles the natural tissue composition. On the other hand the application of plasma directly on cells or on cell culture media (plasma medicine) should promote a selective improvement of cell proliferation on 3D porous scaffolds stimulating in turn the regeneration of new tissue.

In association with Maastricht University (Prof. L. Moroni), we aim at engineering functional biomaterials to create 3D scaffolds able to control cell fate. This challenge is approached through a biomimetic design inspired by cell niches. Several strategies are being pursued, comprising smart coatings (e.g. layer-by-layer technology), chemical functionalization (e.g. covalent vs dynamic binding), and physical modification of surface properties (e.g. stiffness vs topography).

Bone-tissue engineering

A deeper comprehension of the biomineralization process is at the basis of tissue engineering and will be instrumental to the further development of regenerative medicine. The achievement of a complete and exhaustive explanation of a process as complex as biomineralization requires the synergy of different advanced experimental techniques. In this framework, we have developed a multi-scale approach–based on different complementary X-ray experimental techniques coupled to new analytical tools, which provide structural and morphological information on the engineered tissues, from the atomic to the micrometric scale. In particular we study the mechanism of mineralized matrix deposition in a tissue engineering approach in which bone tissue is formed when porous ceramic constructs are loaded with bone marrow stromal cells and implanted in vivo.
High resolution X-ray Phase contrast Tomography (XPCT) provides the 3D spatial distribution of the different tissues participating to the biomineralization process; Scanning X-ray micro diffraction (XRmD) exploits the focused sub-micrometer X-ray beam to achieve atomic information with high spatial resolution. Scanning through the beam the organic–inorganic interface, within a porous scaffold of the sample, we are able to distinguish and monitor the evolution of the different ‘players’ of the regeneration process (Collagen, Organic Matrix, Hydroxy Apatite (HA), amorphous calcium phosphate (ACP)). X-ray Fluorescence (XRF) verifies the chemical evolution of the different growing phases and investigates the distribution of Ca in the regenerated bone. This multi-technique approach provides information on the first steps of biomineralization: we investigate the precursor of the biomineralization, the ACP working as a Ca reservoir, the dynamics of the collagen which is anisotropically distributed far from the scaffold interface but strongly packed at the organic–inorganic interface. When Ca ions are sequestered inside the collagen gaps, the mineralization starts to develop and bone nanoparticles appear at the scaffold interface.
To monitor the relation between bone formation and vascularization, it is important to achieve a detailed imaging and a quantitative description of the complete three-dimensional vascular network in such constructs. We imaged the 3D vascularization network inside the scaffold, without any sample sectioning and preparation. This study of angiogenesis in tissue engineering is crucial for the evaluation of the performance of an artificially implanted construct. Indeed the control of the angiogenesis of the micro-vascular network with proper spatial organization is a key step to obtain tissue regeneration and repair.

Giovedì 19 Luglio dalle ore 11 alle ore 14 nella sede del CNR Nanotec di Lecce si è tenuto un incontro sul trasferimento tecnologico nel settore delle nanotecnologie applicate al settore biomedicale.

L’evento è stato organizzato dall’ufficio di Trasferimento Tecnologico del CNR Nanotec che ha inaugurato con questa giornata un ciclo di eventi mirato a presentare agli attori dell’ecosistema dell’innovazione nel settore delle nanotecnologie i vari modelli e alcune best practice di trasferimento tecnologico. In questa prima giornata il dott. Heber Verri e la dott.ssa Paola Urbani hanno presentato il nuovo modello di trasferimento tecnologico PhD TTãIndex Model.

PhD TT è una realtà italiana completamente indipendente specializzata in trasferimento tecnologico, è un acceleratore organizzato per il Go to Venture Practice, orientata al mondo delle Lifes Sciences.

PhD TT ha sviluppato un nuovo modello di trasferimento tecnologico: il PhD TT©INDEX MODEL dedicato alla generazione di valore dell'innovazione, focalizzato alla riduzione dei rischi delle opportunità di investimento a sostegno della ricerca.

I ricercatori intervengono attivamente nell'analisi iniziale di fattibilità e nella costituzione della futura società (start-up), con l'obiettivo di attrarre capitale di rischio utile a sostenere la fase del trasferimento tecnologico nella visione della "Research for go-to-market".

Il modello PhD TT nasce da un bisogno del mercato, quello di far dialogare due mondi estremamente diversi tra loro: il mondo della ricerca e il mondo degli investimenti.

PhD TT supporta tutte le attività in collaborazione con il TTO - CNR Nanotec con un team di lavoro esperto e grazie a un comitato scientifico-economico qualificato.

In occasione dell'evento del 19/7 u.s. al CNR Nanotec di Lecce, PHD TT ha presentato il proprio track record, dove si sono potuti valutare in dettaglio i casi di successo di intervento del PhD TT©INDEX MODEL.

Disordered serendipity: a glassy path to discovery

A workshop in honour of Giorgio Parisi’s 70th birthday

September 19-21, 2018 - Roma

Sapienza University

With the occasion of celebrating Giorgio Parisi 70th birthday, the conference "Disordered serendipity: a glassy path to discovery" brings to Rome many among the world-leading experts in the field of complex systems. In order to properly represent the many fields of research where Giorgio Parisi gave a relevant contribution in his studies of disordered systems, the conference covers a broad spectrum of topics: from  fundamental and rigorous analysis of the statistical mechanics of disorder systems to applications in biology and computer science. These subjects are deeply interconnected since they are characterized by the presence of glassy behavior.
