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.

Stanford scientists grow vascularized heart and liver organoids

For over a decade, scientists have been growing organoids - small clusters of cells that mimic a particular organ - to serve as miniature biological models.

St. Jude scientists discover how retinoic acid selectively kills metastatic neuroblastoma cells

Neuroblastoma is a solid tumor that occurs in children. When high-risk, the disease has a poor prognosis. Decades ago, adding the drug retinoic acid to neuroblastoma treatment increased survival by 10-15%.

Study unveils role of TLE6 in male sperm development

Infertility is a major global challenge associated with physiological and psychological impact. Genetic mutations that affect early embryonic development, oocyte (egg cell) maturation, and fertilization have recently been studied as causes of infertility.
