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.

Embryonic Cells Pressed into Organizers: Mechanism Unveiled

A collaboration between research groups at the University of California, TU Dresden in Germany and Cedars-Sinai Guerin Children's in Los Angeles has identified a mechanism by which embryonic cells organize themselves to send signals to surrounding cells, telling them where to go and what to do.

Scientists Develop First Full Model of Early Human Central Nervous System with Stem Cells

The first stem cell culture method that produces a full model of the early stages of the human central nervous system has been developed by a team of engineers and biologists at the University of Michigan, the Weizmann Institute of Science, and the University of Pennsylvania.

Specialized Proliferative Cells Contribute to Epithelial Regeneration in Jellyfish

At about the size of a pinkie nail, the jellyfish species Cladonema can regenerate an amputated tentacle in two to three days -; but how? Regenerating functional tissue across species, including salamanders and insects, relies on the ability to form a blastema, a clump of undifferentiated cells that can repair damage and grow into the missing appendage.

Case Western Reserve Biochemists Find New Approach to Stop Cancer Growth

Case Western Reserve University biochemical researchers have identified a new function of a key protein that leads to cancer–a finding they believe could lead to more effective treatments for a range of cancers and other diseases.

NSL Complex Regulates Intraciliary Transport Genes in Multiple Cell Types

The non-specific lethal (NSL) complex is a chromatin-associated factor that has been shown in both fruit flies and mammals to regulate the expression of thousands of genes. Abrogation of the NSL genes causes the organism to die, which gives rise to the complex’s unusual name.

Analyzing DNA Damage-Induced NF-κB Targeted by Novel Small Molecule Inhibitors

Chemotherapy and radiotherapy aim to destroy cancer cells by inducing DNA double-strand breaks – damage that, once inflicted, usually causes the cells to die. But damage to a cell's genetic material also activates a signaling pathway called IKK/NF-κB that helps prevent cell death, thus limiting the success of these treatments in patients.
