The Moroni lab develops new biofabrication technologies to generate libraries of 3D scaffolds able to control cell fate. This passes through the design of biomaterials, 3D scaffolds, and surface properties to better understand cell-material interactions.
Current tissue engineering and regenerative medicine products suffer from high costs and laborious techniques that complicate scaling-up production. First generation products consisted of cells in suspension, encapsulated in hydrogels, or seeded into 3D porous matrices. These products demonstrated the potential of regenerative medicine therapies by reducing pain and restoring tissue continuity. Yet, the regenerated tissue is not always as functional as the original one. This leads to degeneration few years after surgery and consequently to the need of another surgery. Causes are different. Cells need to be expanded before achieving a sufficient number for implantation. Cell expansion is typically performed on 2D surfaces, while in the body cell proliferation and homeostasis happens in a 3D environment. This is associated with a loss of the original cell phenotype. Consequently, the expanded cells produce a different extracellular matrix (ECM), ultimately resulting in a tissue formation that is different than the targeted tissue to regenerate. Furthermore, surgical procedures with these products typically consist of two steps, namely isolation and expansion of cells from a tissue biopsy and cell seeding on scaffolds prior to implantation. This is associated with long hospital stay and rehabilitation time, increasing healthcare costs as well.
Our overarching goal is to create new solutions for regenerative medicine and understand the fundamental phenomena at the base of the observed regenerative processes.
Many tissues in our body display a variable degree of fiber curliness, which is crucial for their biomechanical behaviour. Methods to replicate such features in scaffolds for regenerative medicine are limited. Here, we show how by simply applying controlled buckling to electrospun fibers, we can fabricate scaffolds with different degrees of fiber waviness at multiple scales.
Certainly bioprinting of a full kidney remains a dream. It will be probably like that for many decades, unless a strong and well funded collaborative effort will be originated in the near future. However, current kidney bioprinting attempts are helping creating more know-how over kidney biology through the biofabrication of 3D in vitro models that can be used to study new treatments for kidney chronic conditions.
After Seoul, Vienna, and Boston, Maastricht was selected to host the next world conference of the tissue engineering and regenerative medicine society. We expect to attract more than 2'000 delegates by 2021 in Maastricht, which is at the center of a European region fervidly active in tissue engineering, regenerative medicine, stem cells, biomaterials, in silico modeling, and biofabrication.
Tympanic membrane (or eardrum) is provided by nature with unique anatomic features that ultimately allow a superb physiologic performance in varying frequency ranges. Several pathologies damage this tissue, including chronic otitis media (COM), which ultimately bring to deafness.
The major aim of our lab is to develop innovative biofarication approaches for regenerative medicine as well as training next generation's talented students and postdocs.
One of the most direct ways of contributing to these causes is by donating towards a research aim or sponsoring any of our group members directly. Please contact Professor Moroni about donations towards research for fighting diseases such as osteoarthritis, cardiovascular, and neural degeneration.
We are greatful to our generous sponsors!
