The paper uses electron microscopy to compare stem-like and differentiated states in Hydra epithelial cells, revealing distinct ultrastructural features that challenge the traditional separation of stem and differentiated cells.

This study examines intercellular bridges in Hydra vulgaris, identifying conserved components and revealing their evolutionary significance in cellular connectivity and coordination.

This paper re-examines the structure of the Hydra nerve net using immunostaining and imaging, revealing two distinct nerve nets in ectoderm and endoderm with no contact between them.

The paper shows the Hippo pathway regulates axis formation in Hydra, upstream of Wnt, by controlling budding, actin organization, and cell proliferation.

The paper investigates post-migratory zebrafish primordial germ cells, finding delayed gene activation, nuclear gyration, and piRNA pathway activation without nuclear Piwi proteins.

This study identifies Tdrd6a as a regulator of Buc protein aggregation, which is essential for forming subcellular compartments that drive germ cell specification in zebrafish.
