CURRENT STEM CELL NEWS

1. Functioning human liver buds grown from stem cells in the lab

Using three types of stem cells, Japanese researchers have grown three dimensional liver tissue buds in the lab and these buds when transplanted in mice started functioning as little livers. Click to read more...

2. Stem cell transplant has helped two patients to stay off HIV medicines

Bone marrow stem cell transplants from healthy donors have helped two HIV positive men with Hodgkin's lymphoma to stay off their anti-retroviral therapy and now for more than a year, there are no traces of HIV in these two patients who are continued to be followed up. Click to read more...

3. Nanog's role in embryonic stem cells re-examined

Contradictory to earlier reports which claimed that the one copy of the gene of the transcription factor called Nanog is expressed at any given time and fluctuations in its expression are responsible for the differences seen in the predilection of individual embryonic stem (ES) cells' to differentiate into specialized cells, a new research has shown that both alleles are expressed and this Nanog's expression is equally variable as that of other transcription factors.Click to read more...

4. Network of Molecular communication in human embryonic stem cells discovered

Scientists have mapped a molecular network in human embryonic stem cells (hESCs) which helps in integration of cell communication signals that are needed to keep these cells in their stem cell state. Click to read more...

5. Study unravels potential roles for vitamin C in early stem cell development and In-vitro fertilization.

Based on a study using stem cells, researchers have identified that Vitamin C helps enzymes which are needed to prevent certain genes from being activated in the embryo soon after fertilization and this finding will help to improve in vitro fertilization techniques and also help in cancer research.

6. Structures of inner ear created from mouse embryonic stem cells in lab.

A novel three-dimensional cell culture method has been able to convert mouse embryonic stem cells into the sensory epithelia of the inner ear containing hair cells, supporting cells and neurons which are essential for detecting sound, head movements and gravity. Click to read more...

7. Stem cell based gene therapy proves successful in three patients with metachromatic leukodystrophy (MLD) and three with Wiskott-Aldrich syndrome (WAS).

Team of scientists from Italy have used blood stem cells as gene delivery vehicles and have been able to treat three patients with metachromatic leukodystrophy (MLD), an inherited genetic disease with encouraging outcome. Using a similar technique, the same team was able to reverse the Wiskott-Aldrich syndrome (WAS), another genetic disease in three other young patients.Click to read more...

8. Microparticles based growth factor deliver technique for better control of stem cell differentiation in vitro.

Gelatin based microparticles have been employed by a research team to deliver growth factors to specific areas of aggregates of differentiating cells or embryoid bodies derived from embryonic stem cells and this method of delivery has shown to provide better spatial control of the cell differentiation process thereby enabling creation of complex three dimensional tissues in the lab.

9. Drug used in anaemia treatment could aid in Stem cell tracking – says study

A team of scientists from Stanford have used a iron supplement called ferumoxytol which i s used in the treatment of anemia to track the stem cells after they are transplanted inside the body. Click to read more...

10. Role of laminin protein on stem cell niche function explored

A new study which has explored the role of a protein called laminin on fruit fly's testis stem cell niche function is important because it will pave way for future research on the study of diseases caused by lamina-based tissue degeneration. Click to read more..

Really???

1. It has been long believed that drinking Green tea improves memory but the mechanism behind was unknown. Recently scientists have identified that an organic chemical called EGCG, (epigallocatechin-3 gallate) which is a key component of green tea actually boosts the production of neural progenitor cells in the brain and this might be the key mechanism behind the improvement in memory.

2. Did you know who coined the term "stem cell"? The term stem cell was first used in 1896 by Edmund Beecher Wilson who described this term as a synonym for a mitotically quiescent primordial germ cell.
