Congratulations Dr Osvaldo Contreras

Congratulations @osvaldoics.bsky.social on being awarded a MAWA/RFF Research Grant - supporting his project Animal Free Human Stem Cell Models to Investigate Congenital Heart Defects. Grateful to the MAWA Trust and the Rozzoli Family Fund for supporting this work.

Thanks for sharing! 🙏🏽😃

Congrats!

Star Scientist - Dr Osvaldo Contreras The Institute's Dr Osvaldo Contreras's work could one day help children born with heart defects and adults facing heart failure live longer, healthier…

Star #Scientist @osvaldoics.bsky.socia is uncovering how hearts grow - and what goes wrong when they don’t. He's mapping the molecular ‘blueprint’ of heart cells to uncover the mechanisms that could one day help damaged hearts repair themselves:

Thank you for the highlight @ishr-aus.bsky.social 🙏🏼❤️

Cannot agree more

Nuclear actin and DNA replication stress regulate telomere maintenance by telomerase - Nature Communications Telomerase recruitment to telomeres is a tightly regulated process which is stimulated by replication stress. Here, the authors identify that nuclear filamentous actin is important for interaction bet...

New @natcomms.nature.com paper today from Tracy Bryan's lab @cmri.bsky.social: "Nuclear actin and DNA replication stress regulate telomere maintenance by telomerase".

Happy our lab could play a small part.

Congrats Tracy, Ash Harman, Noa Lamm and the whole team.

💡Dr Osvaldo Contreras’s funds will allow for open access publication of “OpenEMMU: A versatile, open-source EdU multiplexing methodology for studying DNA replication and cell cycle dynamics” in iScience.

We are all mosaics: vast genetic diversity found between cells in a single person Technical advances allow researchers to trace the genetic changes that occur over time.

“There were some cells in there that were very messed up”

In a technological tour-de-force, researchers have sequenced the whole genomes of more than 100 individual cells from one 74-year-old man

Cool work!

In vivo differentiation of embryonic cells devoid of key reprogramming factors Youlten, Miao et al. use zebrafish transplantation to understand the fate of cells lacking pluripotency factors Nanog, Pou5f3, and Sox19b (NPS) in developmental reprogramming and cell identity establishment. They found that NPS are required for proper cell identity for most, but not all, lineages, likely through nuclear and cytoplasmic reprogramming.

Transitions is the newest in our series of stem cell conversations. Launched by Ritika Saxena, Jarmon Lees and @osvaldoics.bsky.social we explore project and career transitions. All the parts needed for successful science that don't make it to the bench. For Aussie scientists, but all welcome.

We are celebrating 5 years of the Australia stem cell conversation! Hosted by @unimelb.bsky.social and @asscr.bsky.social the stem cell conversation is a weekly 30min virtual seminar series organised by EMCR for EMCR.
Join the first 'transitions' episode Leadership through Service: 11am AEST Wed.

I’m very excited to be invited to present at “Development Presents…”

Thanks @amjeve.bsky.social

Remarkable conference organized by @asbmbaus.bsky.social up in Brisbane at the University of Queensland.

I was invited to present my latest work as a Keynote Speaker for the Multi-Sonic’s session, and so many thanks for selecting me!

Truly an honour!
