Excellent account of the evolution of models of human embryos for the last 150 years. N. Hopwood shorturl.at/4Dbdf Journey through the landmarks of human embryology and its representations. Yes, #EmbryoModels is not something we have just run into #MustRead #HistoryMatters

Proud to see that our work made it to @TIME 2023 best inventions on the experimental category. Thanks to all Hannalab members @jacob_hanna for this ongoing journey.

Moment of escapism: Hanna lab human complete embryo model (SEM) made it to @TIME 2023 best inventions. "Find out why Human Embryo Model is one of TIME's best inventions of 2023 ti.me/3sahgtp " Kudos to @Beroldak who led this effort @Nature nature.com/articles/s4158…

📣 Our fun journey continues - latest lab preprint is now out in @Nature Check out in great detail how we derive Complete and Structured human day 14 post-implantation embryo models (SEMs) solely from unmodified HENSM naïve ESCs @Beroldak @EmilieWildschu1 @vlad_bndk @noashefi

Thanks @nmoris for insightful N & V @Nature in which u also invested in making an figure that reflects the very different structures in the 3 papers covered, including our own. Stem cells used to model a two-week-old human embryo nature.com/articles/d4158…

Weizmann Institute of Science researchers have created complete models of human embryos from stem cells for the first time! Today, this groundbreaking research by Prof. @Jacob_Hanna’s team at the Molecular Genetics Department was published in the scientific journal @Nature (1/4)

Mind-blowing paper in which stem cells self-organise into postimplantation human embryo-like structures @Nature @jacob_hanna Happy to have made a small contribution by validating the extraembryonic mesoderm cells made in this study. nature.com/articles/s4158…

Here - in print in tomorrow's Observer - I try to bring some context to the many (sometimes hyped or misleading) recent media report of "synthetic human embryos" - or as we should really call them, embryo models. theguardian.com/science/2023/j…

Four teams have coaxed human stem cells to organize themselves into embryo-like forms. The advance could shed light on fertility. nyti.ms/43WvuvO

Biologists trying to create laboratory models of the early growth of a human embryo have taken a major step forward. scim.ag/32S

Yes, the model by @jacob_hanna is probably the model that gave me the most important uncanny feeling so far because the resemblance to the human embryo is so remarkable - as I also commented in press. However, it’s still a model, as the authors also point out (4/n)
