Scientist Laura De Laporte (DWI – Leibniz Institute for Interactive Materials and RWTH Aachen University) has been awarded one of the most highly endowed research grants of the European Research Council (ERC): an ERC Consolidator Grant. This will fund the expansion of her research over five years. In her project "HEARTBEAT", De Laporte and her team aim to grow vascularized, structured and beating human heart tissue in the laboratory. Her approach is to use interactive, micron-scale rod-shaped polymer networks - called microgels - to produce 3D constructs in high-throughput for growing human millimeter-sized heart tissues.
The Belgian scientist Prof. Dr.-Ing. Laura De Laporte (DWI – Leibniz Institute for Interactive Materials and RWTH Aachen University) has been awarded one of the most highly endowed research grants of the European Research Council (ERC): an ERC Consolidator Grant. This will fund the expansion of her research at the DWI in Aachen over five years with a budget of three million euros. In her project "HEARTBEAT", De Laporte and her team aim to grow vascularized, structured and beating human heart tissue in the laboratory. She wants to break with traditional methods of producing 3D biomaterials: Her approach is to use interactive, micron-scale rod-shaped polymer networks - called microgels - to produce 3D constructs in high-throughput for growing human millimeter-sized heart tissues. With a spatially controllable arrangement and movement of the microgels, she aims to build macroporous scaffolds with the ability to orient cells and enhance cell-cell interaction.
In the first step of the project, different types of microgels will be automatically assembled, magnetically aligned, and chemically interlinked in the presence of induced pluripotent stem cells to expand and organize the stem cells before differentiating them in cardiac cells. The 3D construct will be actuated with light to mimic the heartbeat and enhance the functionality of the growing tissue. In a second step, the aim is to grow blood vessels into the tissue to provide nutrients and oxygen to the growing mini-heart tissue. To achieve this, part of the microgels will be designed in such a way that they can be degraded on demand to ensure sufficient space for growing blood vessels.
"This project is a major step towards complex and interactive materials, as we know them from nature and thus also from the human body," explains De Laporte. Indeed, until now it has not been possible to create functional and personalized tissues including the biological structures and mature blood vessels. The main reason for this limitation is that current materials cannot replicate the complexity and dynamics of the natural cellular environment. "HEARTBEAT's unique bio-inspired 3D constructs – characterized by their macroporous and aligned structure – will resemble the complex biological architecture. At the same time, the actuation of the microgels mimics the heartbeat," describes De Laporte. The project aims to unravel how material properties, architectures, and the actuation of the microgels affect the formation and vascularization of human cardiac tissue, and how the construct needs to adapt to the growing tissue over time to provide the proper extracellular environment. Being able to grow functional human mini-tissue in a high-throughput, automated manner will provide a platform for drug testing and studying diseases, reducing the need for animal studies and better representing the human body, also with the possibility to grow patient-specific tissues.
About Laura De Laporte
Laura De Laporte studied chemical engineering at Ghent University (Belgium). She received her PhD from Northwestern University (Evanston, USA) in the group of Prof. Lonnie Shea, where she developed guided implants for nerve regeneration. At EPFL (Lausanne, Switzerland), she researched regenerative hydrogels in the group of Prof. Jeffrey Hubbell. From 2013 to 2018, Laura De Laporte led a junior research group at DWI – Leibniz Institute for Interactive Materials in Aachen and was awarded a Starting Grant from the European Research Council in 2015. In October 2017, she completed her habilitation at the Department of Chemistry of RWTH Aachen University and since December 2020 she is an associate professor in this department with the teaching and research area Advanced Materials for Biomedicine with additional affiliation to the University Hospital RWTH Aachen. In 2018, she was one of five excellent female researchers who have received funding from the Leibniz Programme for female Professors.
About the ERC Consolidator Grant
ERC Consolidator Grants are considered one of the most prestigious funding instruments in Europe. They intend to support researchers in establishing their own research team or program, according to the ERC. To receive them, scientists have to demonstrate the groundbreaking character, ambition, and feasibility of their scientific proposal. Laura De Laporte, professor in the teaching and research area Advanced Materials for Biomedicine, will receive €3 million in funding from the ERC over five years.
DWI - Leibniz Institute for Interactive Materials
The DWI - Leibniz Institute for Interactive Materials is a research institution of the Leibniz Association funded by the German federal and state governments and is located in Aachen. The institute became Aachen’s first institute to join the Leibniz Association on January 1, 2014. It evolved from the German Wool Research Institute, which was founded in 1952 at the instigation of the German wool textile industry. Today, the DWI is an interdisciplinary research institute in the field of materials science with core competences in chemistry, biotechnology as well as process engineering and employs more than 200 people.
The DWI pursues the goal of developing material functions that were previously only known from living matter. These include the ability to adapt to changing external conditions, to heal defects and to interact with the environment. These innovative materials are expected to enable advances in areas such as medicine and diagnostics, as well as mobility, the environment and sustainability, thus contributing to a better quality of life in the 21st century.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
