Embryogenesis News and Research

RSS

Embryogenesis is the process by which the embryo is formed and develops, until it develops into a fetus. It starts with the fertilization of the ovum (or egg) by sperm. The fertilized ovum is referred to as a zygote. The zygote undergoes rapid mitotic divisions with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo.

Transposable Elements Drive a Critical Transition in Early Embryogenesis

Researchers at Sinai Health have discovered that DNA elements known as transposons, which may travel throughout the genome, control a crucial stage in early human development instead of human genes.

Cell Division Variability Promotes Healthy Embryo Development

There is variability in when and how cells divide during the development of embryos. While researchers traditionally believed this variability was an obstacle that needed to be regulated, the Hiiragi group now found that it actually promotes healthy development.
