To conclude this very successful participation, Nuria’s poster has received the conference best poster award. Congratulations!

Nuria Torras participates in the Youth and Science program and hosts a high school student for three weeks in the laboratory

Youth and Science program from La Pedrera Foundation in Barcelona puts together 15–16-year-old students with scientists from different fields and allow them to perform a small research project. Nuria Torras took part in this engagement activity and hosted Lola Dagà for 3 weeks at the Biomimetic systems for cell engineering group from the Institute for Bioengineering of Catalonia (IBEC).

The Catalunya La Pedrera Foundation is a private and independent foundation, led by a board of trustees comprising experts in different fields, which focus their efforts on carrying out projects that have a positive impact on people’s quality of life. Among those projects we can find the Youth and Science program, oriented to 4th year of compulsory secondary school (ESO) students. The goal of this program is to encourage student’s scientific-technological vocations offering them the opportunity to experience research firsthand and the chance of fully cultivating their skills.

For three weeks this Summer, Nuria Torras, B-BRIGHTER researcher at the Biomimetic systems for cell engineering group lead by Elena Martinez at IBEC in Barcelona, hosted a student in the frame of this program. From the 26th of June to the 14th of July, Lola Dagà could experience what it is like to be a researcher. This 15 years old student had a small research project entitled: 3D bioprinting of biological models: manufacturing and case study.

Among others, Lola learnt how to use light-based 3D bioprinting to manufacture several tissue models, by combining hydrogels and different cell lines, and how to prepare inks for bioprinting. Part of the training consisted in studying the effects of the geometry and various printing parameters in the model to optimize the results. Additionally, she could culture the manufactured samples and monitor cell behaviours through immunofluorescence and microscopy techniques (basic and confocal optical microscopy).

In addition to the practical work, Lola also learnt what is a scientific paper and how to find them in the literature, and how to present and discuss her work and results with team members, for example during the weekly meetings. This was a great experience for Lola who opened her mind to scientific research and developed a critical thinking. These kinds of engagement activities are very valuable to stimulate scientific vocations.

What is 3D bioprinting? B-BRIGHTER researchers explained that and more at the “Science Party” in Barcelona.

The 16th Science Party (“Festa de la Ciència” in Catalan) took place last 10 – 11 of June in Barcelona. Researchers from the Institute for Bioengineering of Catalonia proposed a hands-on activity to bring B-BRIGHTER project closer to the society.

One more year, the streets of Barcelona, Spain, filled with science and people interested in it. The 16th edition of the Science Party was a great success and for two days, participants had the opportunity to engage in a diverse array of actions proposed. Shows, workshops, experiments, guided tours, microtalks, games, and debates composed a total of 177 activities that attracted approximately 16,000 visitors.

Researchers Nuria Torras, Marcel Sorribas and Angela Cirulli from the Biomimetic systems for cell engineering group at the Institute for Bioengineering of Catalonia (IBEC) in Barcelona were in charge of this outreach activity in the frame of B-BRIGHTER project, entitled “3D BIOimpression: how can bioengineering help solving health problems”.

The activity began with a brief presentation in which researchers explained what is a 3D bioprinter and how it can be employed in the field of medicine and health, such as in the fabrication of organs to transplants and to reduce animal testing by substituting animals by 3d bioprinted models. Assistants could then see, in live, how a jawbone was fabricated by a conventional 3D printer while learning from the researchers how we can print live human tissues and how works a 3D Bioprinter.

Visitors could also observe under a microscope and compare samples of real human tissues with others fabricated in the laboratory by bioimpression, such as skin and intestine. They could also wear gloves and manipulate some of the materials used in the laboratory such as Petri dishes with cell cultures, tubes with nutrient solutions for cells and pipettes.

These types of outreach activities are an excellent method for bridging the gap between science and the general public, as well as for enhancing awareness of the significance of research in our daily lives and within society as a whole.

The Technion team invited to present B-BRIGHTER at the “Epithelial Differentiation and Keratinization” Gordon Research Conference

B-BRIGHTER was present at the prestigious Gordon Research Conference 2023 on “Epithelial Differentiation and Keratinization”, held last 04-09 of June in Castelldefels, Spain. The team of Ruby Shalom-Feuerstein from Technion – Israel Institute of Technology was invited to present their last advances in the research of cornea stem cells.

The Gordon Research Conference (GRC) on Epithelial Differentiation and Keratinization stands as a foremost global scientific event dedicated to propelling the boundaries of knowledge, showcasing pioneering and previously unreleased research. This year, the meeting is entitled “Novel mechanisms of regulation in epithelial biology and their implication in physiology, aging and disease”, and strives to unite distinguished speakers who are pioneers in the field of stem cell biology, cancer, regenerative medicine, immunity, aging, epigenetics, skin diseases, novel single cell molecular technologies, global genomics, and novel therapies.

In this context, Shalini Dimri, a postdoctoral researcher at Dr. Ruby Shalom-Feuerstein’s Lab at Technion, Israel, gave a talk about the work on stem cells being carried out in their laboratory in the frame of B-BRIGHTER project, under the title: “Repair of total stem cell loss: a lesson from the transparent “skin” of the eye”.

Shalini began her talk by introducing B-BRIGHTER project and technology, and afterwards she focused on the use of cornea as a robust stem cell model. She emphasized its assets as it allows tracing stem cells in live with simple microscopy, observing spatial segregation of stem cells and differentiated cells, and a robust regeneration, among other advantages. To conclude her presentation, she mentioned that differentiation is a reversible process, central cornea shows high plasticity and dedifferentiated cells display bona fide stem cell features.

The Gordon Research Conference puts a strong emphasis on encouraging discussions following each presentation and cultivating casual exchanges among scientists at every stage of their careers. The conference agenda boasts a rich array of speakers and discussion leaders hailing from institutions and entities across the globe, converging to explore the most recent advancements within the domain. For sure it has been a very fruitful event for B-BRIGHTER project. 

ASTRoLAB: a project to send B-BRIGHTER technology to the space

What would happen if we could do human tissue bioprinting under 0g? This is the key question of ASTRoLAB: Advanced Space-based Tissue Regeneration with Light-sheet Assisted Bioprinting. This side-project based on B-BRIGHTER technology has been recently submitted to the European Space Agency (ESA).

B-BRIGHTER consortium members recently presented a project in the frame of the ESA Payload Master call, with the aim to send the project’s light-sheet bioprinter to space and perform some experiments to check-out if there outcomes improve while working under 0g.

The main points of the proposal are:

– Bioprinting under 0g substantially improves the quality of the engineered tissues, by allowing a level of homogeneity of the cell-gel mixture that is not achievable in a g-field 20 µm resolution.

– We want to show that manufacturing engineered tissues in 0g offers enormous advantages compared to manufacture on Earth.

– We aim to demonstrate that the top-down bio-printing process offered by the LS-Bioprinter is much more suitable to 0g applications than the conventional extrusion methods.


The ESA Payload Masters program serves the dual role of fostering and discovering groundbreaking in-orbit experiments and cutting-edge technologies for payloads. Simultaneously, it plays a pivotal role in democratizing space exploration, making it accessible to both space and non-space industries. The main objective of the program is to enhance the competitiveness of companies by eradicating the well-known “valley of death” phenomenon and giving access to in-Orbit Demonstration and Validation (IOD/IOV).

The project winners of the call will be offered the opportunity to fly their payloads/microgravity experiments on board of Nyx for the “Mission Possible” mission. Nyx is a modular and reusable orbital vehicle that can be refuelled in orbit and serves the low Earth orbit (LEO) and lunar destinations. It will start by carrying cargo, with the growth potential to fly humans afterwards. Nyx will enable to perform microgravity experiments, in-orbit technology demonstrations, entertainment, and educational missions, but also cargo delivery to larger space infrastructures or lunar surface.

Let’s keep fingers crossed and hope ASTRoLAB will be selected!
