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.
The two rounds of whole-genome duplication that occurred throughout the evolution of vertebrates were followed by functional divergence in terms of regulatory circuits as well as gene expression patterns.
DNA methylation is a critical epigenetic alteration for mammalian development.
One out of every 500 to 1,000 boys is born with one or more extra X chromosomes, which can cause a variety of symptoms as the extra chromosomes to including infertility, larger breasts, osteoporosis, diabetes, cardiac problems, intellectual incapacity, and cancer.
Scientists have mapped out the key molecular changes that orchestrate how embryonic mouse cells differentiate into the diverse cell types that will ultimately form all the different tissues and organs of the adult animal.
Citrus is a significant and economically beneficial horticultural crop with nucellar polyembryony, which prevents hybrid offspring from being produced. Citrus is produced mostly through asexual methods like grafting and cuttings.
Divide, differentiate or die? Making decisions at the right time and place is what defines a cell's behavior and is particularly critical for stem cells of an developing organisms.
A new study has led to the discovery that the Hippo signaling effector YAP1 is a master controller of Nodal signaling in hESCs for a process crucial to human development.
A group of scientists headed by the Agency for Science, Technology and Research’s (A*STAR) recently identified a new gene.
Clemson researcher Chris Saski admits sending the University's iconic Tiger Paw to space aboard a SpaceX Dragon spacecraft is, quite literally, "an out-of-this-world experience."
An interdisciplinary team led by KU Leuven and Stanford has identified 76 overlapping genetic locations that shape both our face and our brain.
Scientists have unveiled a range of proprioceptive neurons and have uncovered a new form of plasticity, indicating neuronal individuality in the nervous system.
Researchers from the group of Catherine Robin at the Hubrecht Institute characterized the molecular landscape of the aorta that supports the generation of the first Hematopoietic Stem Cells (HSCs) in the embryo.
