Embryonic Development News and Research

RSS

Embryonic development or embryogenesis is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum, egg, which, after fertilization, is then called a zygote. The zygote undergoes rapid mitotic divisions, the formation of two exact genetic replicates of the original cell, with no significant growth (a process known as cleavage) and cellular differentiation, leading to development of an embryo.

Sperm RNA profiles could identify the best embryos for IVF

Findings on sperm RNA suggest new biomarkers for IVF success, potentially improving embryo selection and reducing cycles needed for desired fertility outcomes.

Researchers create over 400 types of nerve cells from stem cells

Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cell in the human brain according to the latest calculations.

Maternal iron deficiency disrupts embryonic sex determination in mice

Developmentally expressed genes play a fundamental role in the formation of a wide range of organs. The Y chromosome-located mammalian sex-determining gene Sry, required for the formation of testis, is activated only within a narrow time window during embryogenesis.
