👉 Blastulae are a type of embryonic cell line derived from embryos that undergoes rapid differentiation into multiple organ structures. These cells can be seen in the early stages of embryonic development and have been used to study the mechanisms underlying organogenesis, development, and tissue repair. Blastulae are typically obtained by cutting the outermost layer of the embryo's developing skin or mesoderm during gastrulation, which is a process that occurs between the blastipin (a protein secreted from
