In honor of the passing of Sir John Gurdon, we will revisit the concept of chimerism across scales in this review from the lab of @drmichaellevin.bsky.social. Grafting and nucleus transplanting have been the cornerstone of modern #devbio. We have come so far! www.sciencedirect.com/science/arti...
Schematic of the study of multiscale chimerism.Subcellular chimeras in algal grafts.Chimeras at different scales: subcellular, molecular, cellular, tissue, organ, and population.What determines the anatomical setpoint of regenerative homeostasis?

Planarian flatworms regenerate after amputation using a resident population of stem cells. This process reliably stops when the correct species-specific head shape is restored. The following thought experiment illustrates the profound knowledge gap in our understanding of the rules of morphogenesis despite ample information about genes required for neoblast differentiation.

Building the start: Unlocking advanced stem cell-based embryo models
Two recent studies from the Silva and Hanna groups optimized chemical induction and culture conditions to derive extraembryonic lineages directly from embryonic stem cells (ESCs) without transgenes, enabling mouse stem cell-based embryo models (SCBEMs) to reproducibly advance to the E8.5–E8.75 stage.

Transgene-free generation of mouse post-gastrulation whole embryo models solely from naive ESCs and iPSCs
Hanna and colleagues show that signaling pathway modulation amplifies the inherent flexibility of genetically unmodified mouse naive PSCs to adopt extra-embryonic cell fate potential. This endows them with the competence to generate up to E8.5–E8.75 transgene-free stem cell-derived embryo models (TF-SEMs) that complete gastrulation and initiate organogenesis within complex extra-embryonic compartments ex utero.
