New discovery about the formation of new brain cells
The generation of new nerve cells in the brain is regulated by a peptide known as C3a, which directly affects the stem cells' maturation into nerve cells and is also important for the migration of new nerve cells through the brain tissue, reveals new research from the Sahlgrenska Academy published in the journal Stem Cells. view more (2009-11-24)
Is hepatic differentiation of embryonic stem cells induced by valproic acid and cytokines?
Embryonic stem (ES) cells, known for their capacity to proliferate indefinitely and differentiate into almost all types of cells including hepatocytes, have raised the hope of cellular replacement therapy for liver failure. view more (2009-11-18)
Cornell researchers identify a weak link in cancer cell armor
The seeming invincibility of cancerous tumors may be crumbling, thanks to a promising new gene therapy that eliminates the ability of certain cells to repair themselves. view more (2009-11-13)
Exploration by explosion: Studying the inner realm of living cells
Scientists in Washington, DC, are reporting development and successful tests of a new way for exploring the insides of living cells, the microscopic building blocks of all known plants and animals. view more (2009-11-12)
Scientists successfully reprogram blood cells
Researchers have transplanted genetically modified hematopoietic stem cells into mice so that their developing red blood cells produce a critical lysosomal enzyme -preventing or reducing organ and central nervous system damage from the often-fatal genetic disorder Hurler's syndrome. view more (2009-11-10)
Taking aim at mysterious DNA structures in the battle against cancer
Designers of anti-cancer drugs are aiming their arrows at mysterious chunks of the genetic material DNA that may play a key role in preventing the growth and spread of cancer cells, according to an article in the current issue of Chemical & Engineering News, ACS' weekly newsmagazine. view more (2009-11-05)
New findings on the formation of body pigment
The skin's pigment cells can be formed from completely different cells than has hitherto been thought, a new study from the Swedish medical university Karolinska Institutet shows. The results, which are published in the journal Cell, also mean the discovery of a new kind of stem cell. view more (2009-10-19)
Fate Therapeutics announces creation of small molecule platform for commercial-scale reprogramming
Fate Therapeutics, Inc. announced today the generation of human induced-pluripotent stem cells (iPSCs) using a combination of small molecules that significantly improves the speed and efficiency of reprogramming. view more (2009-10-19)
Afib triggered by a cell that resembles a pigment-producing skin cell

Stem cell success points to way to regenerate parathyroid glands
An early laboratory success is taking University of Michigan researchers a step closer to parathyroid gland transplants that could one day prevent a currently untreatable form of bone loss associated with thyroid surgery. view more (2009-09-30)
New study resolves the mysterious origin of Merkel cells
A new study resolves a 130-year-old mystery over the developmental origin of specialized skin cells involved in touch sensation. view more (2009-09-28)
Shedding light on cancer cells
Scientists label cells with coloured or glowing chemicals to observe how basic cellular activities differ between healthy and cancerous cells. Existing techniques for labelling cells are either too slow or too toxic to perform on live cells. view more (2009-09-25)
Toward a nanomedicine for brain cancer
In an advance toward better treatments for the most serious form of brain cancer, scientists in Illinois are reporting development of the first nanoparticles that seek out and destroy brain cancer cells without damaging nearby healthy cells. view more (2009-09-10)
'Liposuction leftovers' easily converted to IPS cells, Stanford study shows
Globs of human fat removed during liposuction conceal versatile cells that are more quickly and easily coaxed to become induced pluripotent stem cells, or iPS cells, than are the skin cells most often used by researchers. view more (2009-09-08)
Unlocking the body's defenses against cancer
Scientists have discovered a way of allowing healthy cells to take charge of cancerous cells and stop them developing into tumours in what could provide a new approach to treating early-stage cancers. view more (2009-08-26)
Tumor suppressor pulls double shift as reprogramming watchdog
A collaborative study by researchers at the Salk Institute for Biological Studies uncovered that the tumor suppressor p53, which made its name as "guardian of the genome", not only stops cells that could become cancerous in their tracks but also controls somatic cell reprogramming. view more (2009-08-10)
Hopkins scientists find cells responsible for bladder cancer's spread
Johns Hopkins scientists have tracked down a powerful set of cells in bladder tumors that seem to be primarily responsible for the cancer's growth and spread using a technique that takes advantage of similarities between tumor and organ growth. view more (2009-08-07)
Noninsulin-producing alpha cells in the pancreas can be converted to insulin-producing beta cells
In findings that add to the prospects of regenerating insulin-producing cells in people with type 1 diabetes, researchers in Europe -- co-funded by the Juvenile Diabetes Research Foundation -- have shown that insulin-producing beta cells can be derived from non-insulin-producing cells in the pancreas. view more (2009-08-07)
Reprogramming Human Cells Without Inserting Genes
A research team comprised of faculty at Worcester Polytechnic Institute's (WPI) Life Sciences and Bioengineering Center (LSBC) and investigators at CellThera, a private company also located at the LSBC, has discovered a novel way to turn on stem cell genes in human fibroblasts (skin cells) without the risks associated with inserting extra genes or... view more...

An 'eye catching' vision discovery
Nearly all species have some ability to detect light. At least three types of cells in the retina allow us to see images or distinguish between night and day. Now, researchers at the Johns Hopkins School of Medicine have discovered in fish yet another type of cell that can sense light and contribute to vision. view more (2009-07-27)
