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.

Researchers discover possible origin of neuroblastoma in the adrenal glands

Neuroblastoma is a childhood cancer, most commonly affecting children aged between 2 -3 and can be fatal. Since the tumor cells resemble certain cells in the adrenal glands, a joint research group from MedUni Vienna's Center for Brain Research and the Swedish Karolinska Institute investigated the cellular origin of these cells and sympathetic neurons during the embryonic development of human adrenal glands.

Researchers describe the key facet of sexual determination in mammalian models

Early in human development, during the first trimester of gestation, a fetus may have XX or XY chromosomes that indicate its sex. Yet at this stage a mass of cells known as the bipotential gonad that ultimately develops into either ovaries or testes has yet to commit to its final destiny.

First-of-its-kind method cryopreserves fruit fly embryos in liquid nitrogen

Cryopreservation, or the long-term storage of biomaterials at ultralow temperatures, has been used across cell types and species.

Researchers discover elusive cell type in fish sensory organs

One of the evolutionary disadvantages for mammals, relative to other vertebrates like fish and chickens, is the inability to regenerate sensory hair cells.

Recreating early embryos using stem cells

In their effort to understand the very earliest stages of life and how they can go wrong, scientists are confronted with ethical issues surrounding the use of human embryos.

Gene-regulatory mechanisms at an early embryonic stage govern the flowering behavior of Arabidopsis

Researchers at GMI - Gregor Mendel Institute of Molecular Plant Biology of the Austrian Academy of Sciences - and the John Innes Centre, Norwich, United Kingdom, determine that gene-regulatory mechanisms at an early embryonic stage govern the flowering behavior of Arabidopsis later in development. The paper is published in the journal PNAS.

HP1a is a key epigenetic regulator that maintains chromosome integrity

The information of the human genome is encoded by approximately 3 billion DNA base pairs and packaged into 23 pairs of chromosomes.

Researchers identify long-sought enzyme that prevents cancer

Researchers have found a long-sought enzyme that prevents cancer by enabling the breakdown of proteins that drive cell growth, and that causes cancer when disabled.

USC Stem Cell scientist receives $2.56 million NIH grant to explore 'synthetic' embryonic development

Whether in an earthworm or a human being, developmental processes are driven by complex networks of genetically-encoded signals that enable cells to take cues from each other and their environment.

Scientists describe the mechanisms that regulate embryonic stem cells

Scientists at the Proteomics Core Unit of the Spanish National Cancer Research Centre (CNIO), headed by Javier Muñoz, have described the mechanisms, unknown to date, involved in maintaining embryonic stem cells in the best possible state for their use in regenerative medicine.

YAP inhibitors could facilitate targeted treatment of basal-like breast cancer

Targeted treatment of basal-like breast cancer could be facilitated by YAP inhibitors in the future. As reported by an MDC team headed by Walter Birchmeier in the scientific journal Cancer Research, this type of cancer requires the support of the YAP protein to stimulate the growth of cancer stem cells.

First model of early human embryo generated from skin cells

In a discovery that will revolutionise research into the causes of early miscarriage, infertility and the study of early human development - an international team of scientists led by Monash University in Melbourne, Australia has generated a model of a human embryo from skin cells.

New method for growing embryos outside the womb

To observe how a tiny ball of identical cells on its way to becoming a mammalian embryo first attaches to an awaiting uterine wall and then develops into nervous system, heart, stomach and limbs: This has been a highly-sought grail in the field of embryonic development for nearly 100 years.

Princeton researchers discover previously unknown organelle that plays role in bone metastasis

Some of Princeton's leading cancer researchers were startled to discover that what they thought was a straightforward investigation into how cancer spreads through the body -- metastasis -- turned up evidence of liquid-liquid phase separations: the new field of biology research that investigates how liquid blobs of living materials merge into each other, similar to the movements seen in a lava lamp or in liquid mercury.

Study reveals physical phenomena relied by oocytes to grow big

Egg cells are by far the largest cells produced by most organisms. In humans, they are several times larger than a typical body cell and about 10,000 times larger than sperm cells.

Loss of functions in the PLD1 gene causes congenital heart disease

A team of researchers co-led by Michael Frohman, MD, PhD, of Stony Brook University, has identified an important cause of congenital heart disease.

A region within GLI1 gene could potentially be targeted as cancer treatment

Scientists from the Stanley Manne Children's Research Institute at Ann & Robert H. Lurie Children's Hospital of Chicago found that a region within the DNA of the cancer-promoting GLI1 gene is directly responsible for regulating this gene's expression.

New hydrogel-based materials show promise for tissue engineering

New hydrogel-based materials that can change shape in response to psychological stimuli, such as water, could be the next generation of materials used to bioengineer tissues and organs, according to a team of researchers at the University of Illinois Chicago.

Biodegradable microcapsules loaded with nerve growth factor can guide neuronal development

Researchers from Skoltech and their colleagues have demonstrated that nanoengineered biodegradable microcapsules can guide the development of hippocampal neurons in an in vitro experiment.

Compound isolated from Ophiura sarsii can be used as an affordable drug for photodynamic therapy

An unusual biologically active porphyrin compound was isolated from seabed dweller Ophiura sarsii. The substance might be used as an affordable light-sensitive drug for innovative photodynamic therapy and for targeted treatment of triple-negative breast cancer and some other cancers.
