Transfection of quail primordial germ cells considerably expands the possibilities of genome modifications in birds, elevating the quail to the rank of genetic laboratory animal models of reference.

The RNA-binding protein NHL-2 is required for small-RNA mediated transgenerational epigenetic gene regulation.

A conserved alternative splicing program is specific to planarian stem cells and is controlled by the highly conserved splicing factors CELF and MBNL; therefore, this mode of regulating stem cells is likely ancestral to all animals.

Reconstitution of DNA loop extrusion in cellular contexts using Xenopus egg extracts shows that condensin extrudes DNA loops non-symmetrically in metaphase, whereas cohesin extrudes DNA loops symmetrically in interphase.

Cells from vertebrate and invertebrate model systems can be reprogrammed into stem-like cells using mouse genes.

In Aves, the first wave of transcription is derived exclusively from the maternal genome.

Inverse gradients of cell ingression and division in the epiblast allow the bipotent progenitors in the anterior streak to become the main progenitors for posterior axis formation from the tail bud.

Finch embryos are laid at an earlier stage than other avian embryos and contain cells with similar properties to pluripotent embryonic stem cells from mice.

Codon optimization through biased synonymous substitutions is a characteristic feature of the genomes of generalist fungal parasites and is associated with the colonization of multiple hosts.

A high throughput, full lifespan microscopic analysis reveals that fission yeast does not age but has a finite replicative lifespan.
