Hematopoiesis: Origin pinned down at last?

AbstractThe sequence of events leading to definitive adult hematopoiesis in the mouse has long been debated. The traditional notion that yolk-sac-derived stem cells seed the adult compartment has now been challenged by evidence that intra-embryonic stem cells play a crucial role

Victoria's Victoria: The Image of Queen Victoria and the Royal Family in the Colony of Victoria, 1851-1901

© 2025 Kim Lorraine Robb Clayton-GreeneThis thesis examines the visual representation of Queen Victoria and the royal family in colonial Victoria (today the state of Victoria, Australia) between 1851 and 1901. Through extensive primary research and the analysis of a diverse range visual materials, this study provides the first comprehensive investigation of royal imagery in colonial Victoria. Challenging prevailing assumptions about the dissemination of imperial visual culture, the research presented here demonstrates that the circulation and reception of royal imagery was primarily driven by local initiative rather than the royal household or colonial administration in Britain. This finding reframes our understanding of how royal imagery operated in practice, suggesting a more dynamic and locally determined process than previously recognised. Across three broad areas of analysis – government, art, and public ceremony – this thesis examines the manifestation and reception of the royal image in colonial Victorian society, tracing the evolution of this imagery alongside the development of the colony. Prominent public works of art depicting the Queen and members of the royal family as well as more ephemeral and temporary royal imagery are considered with an especial focus on the role of identity making, ceremony and ritual, gender and notions of visual reproduction and replication. Acknowledging the contested place that the royal image continues to occupy in Victoria today, it is suggested that the findings presented here provide a valuable historical context for contemporary debates about the enduring legacy of colonialism within the sites of the former British Empire
