Margarida Ribeiro Vilaça. She completed the BSc in Biochemistry (2021; final classification – 17/ 20) and the MSc in Biochemistry (2023; final classification – 19/ 20) by the Faculty of Sciences (FCUP) and the School of Medicine and Biomedical Sciences (ICBAS) from the University of Porto (U. Porto). She has been part of the team of the Laboratory of Histology and Embryology from ICBAS – U. Porto since 2019, and the Team of Animal Morphology and Toxicology, from the Interdisciplinary Centre of Marine and Environmental Research (CIIMAR – U. Porto) since 2021, where she has used fish models in ecotoxicology and mechanistic toxicology studies. Very soon after enrolling in the BSc’s first year, she started a voluntary internship in the Laboratory of Histology and Embryology from ICBAS – U. Porto. She learned and improved basic histological techniques, which she put into practice in the BSc’s final internship project (final classification: 20/ 20). In this project, she studied the independent and combined effects of a warmer temperature and 17a-ethynylestradiol in guppy liver. Indeed, she evaluated some biometric parameters such as the liver mass (and volume), the hepatic cellularity and the volume of the hepatocytes (and respective nucleus). This practical work had been continued until very recently, and a paper describing was published in July 2025. In her MSc dissertation (final classification: 19/ 20), replaced the previous in vivo model with an in vitro one. Specifically, she worked with a 2D culture of a cell line derived from rainbow trout liver (RTL-W1) and developed a 3D model from the same cell line. With the 2D model, studied the combined effects of temperature and pollutants prevalent in aquatic ecosystems (the endocrine disruptors and polycyclic aromatic hydrocarbons). She published two original articles about the dissertation work. The 3D model was created using ultra-low attachment plates and is under morphological (biometric parameters and cytology) and functional characterisation. During the MSc, acquired experience in cell culture and molecular biology techniques. The works that have developed were already presented at the following international conferences (as posters): “XIII Congress of the Iberian Association of Comparative Endocrinology – AIEC (Online)”, “SETAC Europe 2022 – SETAC Europe 32nd Annual Meeting”, “XIV Congress of the Iberian Association of Comparative Endocrinology – AIEC (Bilbao)” and at “The 1st International Electronic Conference on Toxics” (as oral presentation). She acquired some teaching experience while working in study rooms and is currently an Invited Assistant, teaching practical lessons in Histology and Embryology to Medicine and Dental Medicine. She enrolled in the PhD in Biomedical Sciences at the beginning of 2025.
