CURRENT STEM CELL NEWS

1. Scientists identify mechanism behind over-production of platelets by bone marrow

By studying the receptor for thrombopoietin, called Mpl, on blood cells it has been identified that thrombopoietin increases platelet count by not directly stimulating megakaryocytes but actullay acting on, stem cells and progenitor cells, several generations back. This discovery has implications in myeloproliferative disorders, such as essential thrombocythemia. Click to read more...

2. Key ingredient used in Silly Putty help turn embryonic stem cells into neurons in an efficient manner - reports study

Employing polydimethylsiloxane - a silicone that gives Silly Putty its unusual stretchy ability, scientists have developed adjustable surfaces for stem cells to grow and they found that embryonic stem cells grown on plush-like surfaces turned into nerve cells more efficiently.

3. Study offers insights into molecular components of Stem cells that hold promise for repairing brain after stroke

By experimenting at the molecular level of stem cells, researchers have suggested that components like tissue plasminogen activator and exosomes may serve as potential therapeutic tools to treat stroke.Click to read more...

4. Scientists transplant tissue engineered oesophagus derived from bone marrow stem cells into rats

Scientists have bioengineered oesophagi using oesophagi from rats which were decellularized and then re-seeded using stem cells from bone marrow. These bioengineered oesophagi were then transplanted successfully to replace segments of the oesophagus in rats. Click to read more...

5. Red blood cells created in large numbers from stem cells using Induced pluripotent stem cell technology

Using Induced pluripotent stem cells derived from a donor, Scientists have successfully grown large numbers of red blood cells in the laboratory and these cells are planned to be tested in human trials. Since the cells are derived from a donor, these red blood cells are hypothesized to better for patients because they will be fresh and young. Click to read more...

6. New abilities of key cell division proteins revealed

Cyclin B1/Cdk1 protein complex which is a key player in cell division, also has been found to boost the mitochondrial activity and thus this complex can serve as a target to control cellular energy production, thus advancing research on cancer therapeutics and regenerative medicine.

7. Stem cells derived from first human embryo clones created in lab using adult skin cells

Using somatic cell nuclear transfer, scientists have successfully created human embryos that are clones of two men and the researchers have used these embryos to derive embryonic stem cells in the lab. Click to read more...

8. Study offers insights into stem cell niches

Experiments on fruit fly testes have shown that in the testes niche, when a certain kind of stem cell is removed experimentally, another group of non-stem cells come out to replace them.Click to read more...

9. Clinical study on retinal pigment epithelial cells derived from embryonic stem cells for retinal disease moves forward

The clinical study on retinal pigment epithelial cells derived from embryonic stem cells for macular degeneration and Stargardt's disease has shown limited but targeted success in the treated patients. Click to read more...

10. Chemotherapy drugs encourage drug-resistance and tumor growth via cancer stem cells - identifies study

A study has reported that cancer cells develop properties that are similar to stem cells and this property enables them to develop drug-resistance and survive throughout the body. Click to read more..

11. Immunotherapy shows promise in advanced pancreatic cancer

Autologous Immune Enhancement Therapy (AIET) using patient's own immune cells has help improve the survival upto 26 months in a patient with advanced pancreatic cancer . Click to read more..

Really???

1. Are you aware that the discovery of stem cells owes to the Unitarian theory of hematopoiesis proposed by Alexander A. Maximow at the end of the ninetenth century? He was the first person to demonstrate that all blood cells are developed from a common precursor cell which is known as the Unitarian theory of hematopoiesis. In 1908 at the congress of hematologic society held in Berlin, he proposed the existence of hematopoietic stem cells and explained his theory during that event. He was the first person to use the term "stem cells".         (Sources: Igor EK. Perspect Biol Med. 2000;43:269–76 and http://discovery.yukozimo.com/)

2. Did you know that the term antibiotic originated from the term 'antibiosis', meaning "against life"? The term 'antibiosis' was introduced by Jean Paul Vuillemin, a French bacteriologist who used this term to describe the phenomenon exhibited by the early antibacterials which were mostly based on the on the antagonism observed between micro-organisms. The phenomenon of Antibiosis was first described in 1877 by Louis Pasteur and Robert Koch who observed the inhibition of growth of Bacillus anthracis by an airborne bacillus. These antibacterial agents were later renamed as Antibiotics by Selman Waksman, an American microbiologist, in 1942.                                             (Source : Wikipedia)
