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 ...

No rebirth for insulin secreting pancreatic beta cells

Pancreatic beta cells store and release insulin, the hormone responsible for stimulating cells to convert glucose to energy. The number of beta cells in the pancreas increases in response to greater demand for insulin or ...

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.
