CURRENT STEM CELL NEWS

1. Study on human embryonic stem cells (hESC) throws light on epigenetic mechanisms that govern hESC differentiation

Salk Institute researchers have studied the key epigenetic modifications that occur in human embryonic stem cells as they differentiate into specialized cells in the body and this study is hoped to help in identifying methods by which good quality cells can be produced for therapy.

2. Induced pluripotent stem cells (iPSCs) used to create 'disease in a dish' model of a rare genetic disease.

Offering a solution for lack of proper animal models to test drugs for the rare genetic disease 'ataxia telangiectasia (A-T)', scientists have been able to model this disease process using induced pluripotent stem cells (iPS) with success Click to read more...

3. Protein that can rejuvenates aged hearts discovered

Harvard Stem Cell Institute scientists have identified a protein that is capable of making thickened and enlarged hearts in aged mice to revert back to a more youthful state.Click to read more...

4. NK cell based immunotherapy for Cancer – the past, present and the future

A comprehensive review has been published on the relationship between NK activity and cancer incidence, monitoring of NK cell number and activity, anti-cancer activities of NK cells in vitro and in vivo, the effects of the combination of expanded NK cells with monoclonal antibody drugs on cancers and on clinical cases of NK cell-based autologous immune enhancement therapy (AIET).

5. Trachea created from patient's own stem cells coated on a synthetic material transplanted with success

A girl born without trachea has been transplanted with an artificial trachea made up of her own stem cells coated on a synthetic material making it the first of its kind transplantations in the world Click to read more...

6. Blend of silk and cellulose – Ideal for growing stem cells for cartilage repair

Blends of silk and cellulose when used as scaffold for connective tissue stem cells, scientists observed that these stem cells formed chondrocytes, cells of the cartilage without the need for biological induction using differentiation factors. Click to read more...

7. New roles for astrocytes in brain healing after injury

Astrocytes produced after brain injury earlier considered as an impediment to healing have been identified as essential to arrest the bleeding that ensues after stroke or head trauma in order to promote healing of the neurons. Click to read more...

8. Stem cell activity for producing eggs doesn't occur in adult mammals- says study

Contrary to earlier reports that claimed the existence of germ line stem cells that gives rise to eggs in adult mammals, a new study has identified that the primordial follicles each one containing an immature egg in adult mice are highly stable, and that germ-line stem cell activity cannot be detected, even if there is depletion of more than half of the primordial follicles.

9. Microglia derived from induced pluripotent stem cells (iPSCs) opens new avenues in treatments for central nervous system (CNS) diseases

Microglia, the resident inflammatory cells of the CNS have been created from human induced pluripotent stem cells (iPSC) in the laboratory and these iPSC-derived microglia will serve as gene and protein delivery vehicles to the CNS in the future apart from their applications in various diseases.

10. Polymer attracting stem cell towards inflamed blood vessels expected to promote healing

A novel method has been devised by scientists to target stem cells to the blood vessels to promote repair. They have used a polymer which will help these stem cells to find and adhere to inflamed endothelial tissue in blood vessels. Click to read more..

11. Orchestrated Stem cell choreography creates patterns in feathers of birds

It has been identified that colorful feather patterns in birds are not directly coded in their DNA, but they rather occur by a complex orchestrated efforts of stem cells in these feathers. Click to read more..

Really???

1. Did you know that James Lind was the first physician to have conducted a controlled clinical trial in the modern era? He conducted a trial in 1747 to find out a cure for the deadly disease scurvy. He divided the scorbutic sailors in his ship into six groups and compared six of the proposed remedies for scurvy. The results showed that oranges and lemons were significantly better than the other supposed treatments.

2. Are you aware that two scientists from Kazakhstan, Vladimir I. shCherbak and Maxim A. Makukov have recently hypothesized that an "intelligent secret signal" could have been embedded in our DNA by higher beings or extra-terrestrials, as the arrangement of the genetic code reveals a co-ordination of arithmetical patterns of a symbolic language which cannot be explained by evolution?
