A new study examines the embryogenesis and eye development of the cave-dwelling spider Tegenaria pagana, providing the first detailed description of its developmental stages. By analyzing gene ...

Magdalena (Magda) Zernicka-Goetz, today a developmental and stem cell biologist at the University of Cambridge and California Institute of Technology, recalled being an artistic child who enjoyed ...

Researchers have gained new insights into the mechanism behind the spatial organization of DNA within the cells of early embryos. When an embryo is first formed after fertilization, each cell has the ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

Descriptions of the embryo go back at least to the time of Aristotle, but it has only been since the late 19 th century and early 20 th century that advances in experimental approaches allowed ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

The mystery of early embryonic communication is starting to be unraveled thanks to a new stem cell-based model.
