The aim of regenerative medicine is not only to recover the integrity of individual organs, but also to maintain the proportions with the rest of the body. The Roselló-Díez group uses animal models to study the local and systemic mechanisms that orchestrate organ growth and repair in vertebrates. The ultimate goal is to lay the groundwork for regenerative therapies aimed at boosting these mechanisms.
The Roselló-Díez group studies the signals that operate within the bones and between them and other tissues/organs during development and regeneration. At the local level, they study phenomena such as compensatory proliferation in response to biochemical and mechanical changes in the cell vicinity. At the systemic level, they are exploring the role of the vascular and nervous systems in the bidirectional communication between the bones and the rest of the body.
Open positions for PhD students
Domestic PhD student
Studying the effects of unilateral cartilage injury in long-term limb growth, articular cartilage health and scoliosis.
This is a funded position, part of the collaboration between Monash and the Chinese University of Hong Kong. The student will spend at least 4 months at CUHK. Contact Alberto Roselló-Díez at firstname.lastname@example.org for more information.

Mechanisms of catch-up growth in developing long bones.
A motivated student is sought for an Honours/Masters project focused on mechanisms of catch-up growth after signal imbalance in mice. Contact Alberto Roselló-Díez at email@example.com for more information.
- Characterising the local cell-autonomous and nonautonomous responses to an injury, including the production and role of alarm signal(s) and the response of stem/progenitor cells
- Dissecting the inter-organ communication mechanisms that lead to systemic growth effects upon local injury, with a focus on the role of the vascular and nervous systems
- Exploring the impact of the discovered injury response pathways on the buffering of developmental noise (random perturbations during normal development)
- Exploiting the discovered injury response pathways for the treatment of animal models of dwarfism and fracture repair
