Mechanobiology of nuclear import of transcription factors modeled within a biongineered stem cell niche.

Many therapeutic applications of stem cells require accurate control of their differentiation. To this purpose there is a major ongoing effort in the development of advanced culture substrates to be used as “synthetic niches” for the cells, mimicking the native ones. The goal of this project is to use a synthetic niche cell culture model to test my revolutionary hypothesis that in stem cell differentiation, nuclear import of gene-regulating transcription factors is controlled by the stretch of the nuclear pore complexes. If verified, this idea could lead to a breakthrough in bio-mimetic approaches to engineering stem cell differentiation.

I investigate this question specifically in mesenchymal stem cells (MSC), because they are adherent and highly mechano-sensitive to architectural cues of the microenvironment. To verify my hypothesis I will use a combined experimental-computational model of mechanotransduction. I will a) scale-up an existing three-dimensional synthetic niche culture substrate, fabricated by two-photon laser polymerization,  b) characterize the effect of tridimensionality on the differentiation fate of MSC cultured in the niches, c) develop a multiphysics/multiscale computational model of nuclear import of transcription factors within differentially-spread cultured cells, and d) integrate the numerical predictions with experimentally-measured import of fluorescently-labelled transcription factors.

This project requires the synergic combination of several advanced bioengineering technologies, including micro/nano fabrication and biomimetics. The use of two-photon laser polymerization for controlling the geometry of the synthetic cell niches is very innovative and will highly impact the fields of bioengineering and biomaterial technology. A successful outcome will lead to a deeper understanding of bioengineering methods to direct stem cell fate and have therefore a significant impact in tissue repair technologies and regenerative medicine.

Bianca Barzaghini obtained her M.Sc. in biomedical engineering in 2019 at Politecnico di Milano, Italy. Here, she is currently attending a PhD program in bioengineering focused on the ERC-funded project NICHOID, in collaboration with the Dr. Stephana Carelli lab at Università degli Studi of Milano. Her research is focused on the microfabrication of micro engineered stem cell niches by two-photon laser polymerization and their biological validation.

Francesca Donnaloja has obtained the Master Degree in Biomedical Engineering in December 2016, at Politecnico di Milano. She has developed her Bachelor thesis project at Ospedale San Raffaele in Milan where she analyzed tissue damage induced by lead extraction. The Master project thesis has involved Baxter company for the analysis of the adsorbent capacity of novel materials to be used in dyalisis process. She has worked as a consultant at EY company in the Life Sciences section. Currently she is a PhD student involved in the ERC-CoG NICHOID project with a reseach activity entitled “Modelling the molecular mechanics of the nuclear pore complex” at Politecnico di Milano.

Dr. Emanuela Jacchetti graduated in Physics at Università degli Studi di Milano where she completed her PhD in Physics, astrophysics and Applied Physics in 2009 with the thesis “Differentiation and cytoskeletal protein dynamics of PC12 cells cultured on nanostructured titanium dioxide surfaces”. Then she worked on the project “Characterization of cytoplasmic calcium kinetics induced in human Mesenchymal Stem Cell”, at Istituto di BioFisica-CNR and Centro di Biotecnologie Avanzate in Genoa. From 2010 to 2014 she was a post-doc researcher at NEST, Scuola Normale Superiore (Pisa) to design and develop micro/nano-structured substrates for cell differentiation and at Istituto di BioFisica – CNR (Pisa) to study the spectroscopic characterization of photochromic fluorescent protein and their use in high spatial resolution microscopy applied to cell systems. In 2015 she was employed at IRCCS San Raffaele Scientific Institute on the project “Development of high resolution microscopy for imaging and tracking individual transcription factors”. She has joined the Mechanobiology lab in 2015 and she is in charge of the activities related to high resolution imaging relevant to the project ERC-CoG NICHOID.
