Summary
The growth factor activin provides key signals in embryonic and infant testes to coordinate development of male germline cells into sperm. This project tests how activin controls genetic stability when the human testis is vulnerable to forming germline cells that become tumours in young men. We will study how activin acts to allow sperm stem cells to multiply and develop in sufficient numbers for adult fertility.

Summary
Lymphocytes are white blood cells that are involved in producing antibodies, killing defective cells, or killing cells infected with viruses. In recent years, researchers have found ways to harness lymphocytes to develop medicines for treating a variety of different cancers. In this project, we will establish methods to make human lymphocytes in the laboratory from stem cells, paving the way for the broader application of this cell type to new therapies.
The Mechanisms Of Epithelial Cell Survival That Govern Thymus Function

Summary
The thymus is an organ dedicated to the production of crucial immune cells, called T lymphocytes. Cancer treatments, such as radiation or chemotherapy, destroy thymic function and impair immune recovery in patients. We aim to uncover molecular processes that govern the life and death decisions of cells in the thymus. Our goal is to then use this information to develop treatments to protect this critical organ from damage and improve immune recovery following radiation or chemotherapy.
Investigating Wnt signaling during human nephron commitment and patterning. Aims: To use gene edited stem cell lines that display cell location, identity and cell state to map human kidney tissue formation in the laboratory. By monitoring how each cell responds to those around it across time and space, we will for the first time map the formation of kidney tissue in the dish.
Significance: Understanding how stem cells form a tissue will help us to improve and control the process. This is key to ....Investigating Wnt signaling during human nephron commitment and patterning.

Significance: Understanding how stem cells form a tissue will help us to improve and control the process. This is key to advancing tissue engineering.
Expected outcomes: The proposal will pioneer state-of-the-art imaging, gene editing and machine learning approaches, generating models of human development that are currently unavailable.
Benefits: This understanding will guide the development of novel approaches to tissue engineering.

Regulation of DNA replication initiation during Drosophila development. This proposal addresses the fundamental issue of the regulation of DNA
replication during development, using the animal model system, Drosophila melanogaster. This research uses a whole animal genetic and cell biological approach to explore DNA replication regulatory mechanisms that are present in multicellular organisms but not in yeast. The work undertaken here will make a significant contribution to our understanding of ....Regulation of DNA replication initiation during Drosophila development.

Summary
Revealing dynamic mechanisms controlling pluripotency in mammalian stem cells and embryos. Every cell of our mature bodies originates from 'pluripotent' cells present in the early mammalian embryo. These cells can be captured and grown in plastic dishes. The project will use imaging methods to reveal how gene regulatory molecules control pluripotent cells in the embryo and in culture.
The structure of heteromeric amyloid fibrils with signaling activity. This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection.

This project aims to determine the composition, structure and properties of important protein complexes involved in a newly identified cell death pathway known as necroptosis. This cell death pathway removes unwanted or damaged cells during development or infection. These necroptosis protein complexes are unusual because they have a fibrillar amyloid structure, contain more than one protein type in the fibrils and have a functional, signalling role. The research will determine how these fibrils form and how the structures confers biological function. It could identify features in these fibrils that can be targeted as a means of ultimately preventing tissue damage after heart attack and stroke.Read moreRead less
