CURRENT STEM CELL NEWS

1. Micro RNA based mechanism that prevents genomic disruption in reproductive cells of plants identified

A new study has reported the discovery of a pathway which helps in maintaining the inactive state of transposons even when the epigenetic code is erased during the process of generation of reproductive cells by plants, as otherwise these transposons if become activated may insert itself within critical genes, disrupting gene function.

2. Scientists develop method to generate human induced pluripotent stem cells (hiPSCs) from a mere drop of finger-pricked blood

A novel methodology has helped to create human induced pluripotent stem cells (hiPSCs) from a mere drop of finger-pricked blood and this technique will help in establishing hiPSC banking . Click to read more...

3. Study reports novel method to develop skeletal muscle cells and muscle progenitors from stem cells

An innovative methodology using a high concentration of two growth factors has been described to generate large numbers of muscle cells and muscle progenitors from human pluripotent stem cells. Click to read more...

4. Sutures embedded with stem cells can help in quicker healing of Achilles tendon - reveals study

A team of researchers have identified that introducing stem cells in sutures leads to a better healing compared to normal sutures in Achilles tendon injuries in rats.. Click to read more...

5. Human stem cells coaxed to form specialized cells needed to repair a diseased bladder in vitro

In a recent study published, scientists have reported their success in making laboratory cultures of human stem cells to convert into the specialized cells of the bladder which will be helpful to repair a patient's diseased bladder in the future. Click to read more...

6. Study on neurons derived from induced pluripotent stem cells (iPSCs) of bipolar disorder patients offers new insights into the disease

Researchers have derived a stem cell line specific to bipolar disorder using skin cells from people with the disorder employing induced pluripotent stem cells (iPSCs) technology and this cell line will be useful for future studies to understand the disorder better. Click to read more...

7. Astrocytes from rats reprogrammed into neurons using Mash1

Earlier it was relatively difficult to reprogram astrocytes into neurons. Now scientists employing a transcription factor called Mash1 have been able to easily reprogram astrocytes from rats into neurons. Click to read more...

8. Encapsulated human embryonic stem cells derived insulin-producing cells hold great promise for Diabetic patients- suggests study

As a hope to Insulin dependent diabetic patients, a new study has shown that implanting encapsulated immature pancreatic cells derived from human embryonic stem cells (hESC) under the skin in animal models of diabetes has resulted in sufficient production of insulin to maintain glucose levels without immunorejection.Click to read more...

9. Model to cultivate cancer stem cells outside the human body through a "paracrine" mechanism developed by scientists

An in vitro model has been developed that employs carcinoma-associated fibroblasts (CAF) to support the survival of cancer stem cells by a paracrine mechanism. Click to read more...

10. Specific cellular patterns of contraction across the wall of the human heart documented in first of its kind study

A recent study has documented for the first time the specific cellular patterns of contraction across the wall of the human heart and it has been discovered that the cellular properties vary in different regions of the left ventricular wall and the middle of the wall has better pumping capacity than the outer edges of the heart.

1. Though monoclonal antibodies have recently gained prominence, are you aware that a similar concept was postulated by Paul Ehlrich in the beginning of the 20th century itself? Paul Ehlrich conceptualized the "magic bullet" (magische Kugel) which he described as a compound that selectively targets a disease-causing organism and that a toxin for that organism could be delivered with this selective compound.                                    Source – Wikipedia

2. Did you know that DNA was first isolated by Friedrich Miescher, a Swiss physician in 1869? He while working on the chemical composition of leukocytes found a precipitate of an unknown substance which was resistant to protease digestion thus indicating that it was neither a protein nor a lipid. Analysis of its elementary composition made Miescher understand that he had discovered a novel molecule. Since he isolated it from the nuclei of cells, he termed it as "Nuclein". Miescher even hypothesized that it might play a role in transmission of hereditary traits but later rejected the idea. (Hum Genet. 2008 Jan;122(6):565-81).
