Few days left to join our ambitious and innovative program using human induced pluripotent stem cells derived hepatocytes for cell based therapies against liver diseases.

We are looking for 2 motivated, ambitious and determined technical assistants.

Neurons and β-cells share many similarities, including the expression of very specific transcription factors. This prompted a long-standing search for connections between diabetes and mental disorders. This amazing discovery finally reveals a mechanistic link!

However, one death due to the immunosuppressive treatment.

Missed our @eisg2025.bsky.social post? If you study beta cell function using rat islets or INS-1 cells, check out Ri-lnc1! Strongly linked to mature beta cells but missing from current rat genome annotations. Overlooked? Happy to collaborate—just contact us!
Great opening yesterday @eisg2025.bsky.social meeting! Glad to see many interesting talks using INS-1 rat cells to study β-cell function—I couldn’t help but wonder how these treatments might affect Ri-lnc1 expression, our recently reported novel rat long non-coding RNA enriched in mature β-cells 👇

Already on my way back to Argentina! Every trip must come to an end, but this one has truly been an amazing experience that will leave a lasting mark. Looking forward to consolidating the exciting new collaborations that will drive future work!

Amazing talks by @diegobalboa.bsky.social, @labspagnoli.bsky.social, Simona Chera and many other colleagues yesterday at @eisg2025.bsky.social ! I'm also really glad for the opportunity to share our recently published work. Looking forward to more exciting talks today!

Thank you, Philip Allan Seymour, for the great meeting today in Copenhagen and for contributing key experiments to our follow-up work on the role of glucocorticoids in pancreas development. Looking forward to getting this continuation story out soon!

Finally! All the pieces are in place for the last stage of an amazing trip. Excited to share our results @eisg2025.bsky.social, showing that endogenous glucocorticoid receptor activation modulates early-stage cell differentiation in pancreatic progenitors of mice and humans!
