In the "black box" of human development known as gastrulation, an embryo transforms from a hollow, spherical structure to a multilayered one. Human embryos are typically not cultured for longer than 14 days due to bioethical concerns, and gastrulation happens between 17 and 21 days after fer
Gastrulation is a "black box" of human development in which an embryo reorganises itself from a hollow spherical to a multilayered structure. Because of bioethical considerations, human embryos are normally not cultured for more than 14 days, and gastrulation occurs between 17 and 21 days po
Researchers at Gladstone Institutes' iPS Cell Research Centre discovered that tight connections between cells play an important role in gastrulation in human embryos. The study was published in Developmental Cell.
