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.
We know a lot about the human brain, but very little about how it is formed. In particular, the stages from the second to the seventh week of embryonic development have so far been virtually unknown territory to brain researchers.
Scientists at the Stem Cell Research program at Boston Children's Hospital and Dana-Farber Cancer Institute/Harvard Medical School have devised a mouse model that lets researchers track every cell in the body, from the embryonic stage until adulthood.
A research team has created the world’s first roadmap of the development mechanism of human skeletal muscles, including the development of muscle stem cells.
A new study released today in STEM CELLS suggests for the first time that regulatory T-cells (Treg) induced by mesenchymal stromal cells can yield an abundant replacement for naturally occurring T-cells, which are vital in protecting the body from infection.
Researchers from EMBL Heidelberg and from the University of Padua School of Medicine have created the first complete description of early embryo development, accounting for every single cell in the embryo.
In association with Stanford University, a working group from the Division of Cell and Developmental Biology at the Medical University of Vienna (MedUni Vienna) has discovered the role of a crucial factor that plays a role in early embryonic development.
