Scientists show how nerve wiring self-destructs
Many medical issues affect nerves, from injuries in car accidents and side effects of chemotherapy to glaucoma and multiple sclerosis. The common theme in these scenarios is destruction of nerve axons, the ...

Making cancer less cancerous: Blocking a single gene renders tumors less aggressive
Researchers at Johns Hopkins have identified a gene that, when repressed in tumor cells, puts a halt to cell growth and a range of processes needed for tumors to enlarge and spread to distant sites. The researchers hope that ...

Scientists develop new therapeutics that could accelerate wound healing
(Medical Xpress)—In "before" and "after" photos from advertisements for wound-healing ointments, bandages and antibiotic creams, we see an injury transformed from an inflamed red gash to smooth and flawless ...

Advance in tuberous sclerosis brain science
Doctors often diagnose tuberous sclerosis complex (TSC) based on the abnormal growths the genetic disease causes in organs around the body. Those overt anatomical structures, however, belie the microscopic ...

'Junk DNA' drives embryonic development
An embryo is an amazing thing. From just one initial cell, an entire living, breathing body emerges, full of working cells and organs. It comes as no surprise that embryonic development is a very carefully ...

Researchers return blood cells to stem cell state
Johns Hopkins scientists have developed a reliable method to turn the clock back on blood cells, restoring them to a primitive stem cell state from which they can then develop into any other type of cell in the body.

Possible role for Huntington's gene discovered
About 20 years ago, scientists discovered the gene that causes Huntington's disease, a fatal neurodegenerative disorder that affects about 30,000 Americans. The mutant form of the gene has many extra DNA ...

Long non-coding RNA molecules necessary to regulate differentiation of embryonic stem cells into cardiac cells
When the human genome was sequenced, biologists were surprised to find that very little of the genome—less than 3 percent—corresponds to protein-coding genes. What, they wondered, was all the rest of ...

Developing our sense of smell: Biologists pinpoint the origin of olfactory nerve cells
When our noses pick up a scent, whether the aroma of a sweet rose or the sweat of a stranger at the gym, two types of sensory neurons are at work in sensing that odor or pheromone. These sensory neurons are ...

Embryogenesis
Embryogenesis (compound of the Greek: εμβρυο-γένεσις "embryo-genesis") is the process by which the embryo is formed and develops. It starts with the fertilization of the ovum (or egg) which, after fertilization, 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. It occurs in both animal and plant development, this article addresses the common features among different animals.
