CURRENT STEM CELL NEWS

1. Novel Stress resistant stem cells discovered in fat removed by liposuction

Stress resistant pluripotent stem cells that can differentiate into almost all types of cells in the body have been discovered by ULCA researchers in fat tissue removed by liposuction. Click to read more...

2. Assay to test safety of pluripotent stem cells developed

An assay that uses laser technology to identify the proteins on the Induced Pluripotent Stem (iPS) cells can now help in recognizing the unsafe iPS cells thus improving the safety of iPS cells to be considered for human application. Click to read more...

3. Combination of drug and adult stem cells to combat Type I diabetes

Researchers have used the combination of a drug and stem cells from the bone marrow to tackle Type I diabetes. The drug will stop the attack of the immune cells on the insulin producing cells while the stem cells will help forming new blood vessels which are needed for the insulin producing cells to thrive and produce insulin.Click to read more...

4. Hydrogels and Cadherin interactions explored for creating cartilage cells from stem cells

To improve the quality of cartilage cells created in vitro, a synthetic hydrogel embedded with peptide sequences that can mimick the Cadherin interactions taking place in native cartilage synthesis have been used in the lab to encapsulate mesenchymal stem cells and it has been found that cartilage thus produced has superior qualities akin to native cartilage present in the body.

5. Breast cancer cells from primary breast cancer tissue of patients and those from cell lines behave similarly- identifies study

A study using an in vitro model has confirmed that breast cancer cells derived from primary breast cancer tissue from patients and those derived from long term cultured established breast cancer cell lines behave in a similar manner thus advancing tools for research on breast cancer.

6. Previously unknown liver progenitor cell developed from embryonic stem cells – liver regeneration to move forward

Scientists have discovered that human embryonic stem cells can be differentiated into a previously unknown liver progenitor cells which can then be used to create mature and functional liver cells for liver regeneration. Click to read more...

7. Role of enzyme HDAC3 in blood progenitor cell function explored

A chromatin modifying enzyme HDAC3 earlier associated with oncoproteins that drive leukemia and lymphoma has now been identified to play an important role in replication of DNA in blood progenitor cells.Click to read more...

8. Signals triggering stem cells for nail and bone regeneration in fingers and toes explored in mice

A study in mice has shown how chemical signals influence stem cells which in turn help in nail and bone regeneration in fingers and toes after amputation and also showed that nerves in these fingers and toes are essential for delivering proteins that promote stem cell based tissue growth.

9. Cross talk between iPS derived neurons and astrocytes help create neurons with better functional potential

Researchers have developed an in vitro culture method in which they cultured Induced Pluripotent Stem (iPS) cell derived neural stem cells along with astrocytes and they observed that the neurons formed in this method exhibited better functional potential. This study will help in advancing lab models to study diseases like Alzheimer's, schizophrenia, and autism. Click to read more...

10. Engineered virus that can be injected into the vitreous humour for gene therapy creates hope to treat retinal diseases.

To overcome the hurdle of the intended genes not reaching the cells of the retina in conventional gene therapy approaches, scientists have engineered a novel gene delivery virus which can be directly injected into the vitreous humour of the eye so as to reach the retinal cells easily.

Really???

1. Did you know that artificial synapse has been created by Japanese scientists using a single nanoscale electrochemical atomic switch and the most exciting part of the research is that the synaptic device they have created essentially mimics major features of human cognition like "emulation of synaptic plasticity" including what happens in long term and short term memory? The device also has ability to respond to presence of air and temperature changes thus indicating that it can possible perceive the environment like the human brain. This invention is considered as a giant leap towards creation of artificial brain.

2.Of serendipitous discoveries in Biology, the discovery of relationship between pancreas and diabetes needs mention. In 1889 two German physicians Joseph von Mering and Oscar Minkowski in order to study role of pancreas in digestion did so by removing pancreas in dogs. Several days after, they observed that the urine secreted by these dogs was swarmed by flies. Later they understood that it is because these dogs whose pancreas was removed were secreting sugar in their urine, thus finding out for the first time, the link between pancreas and Diabetes.
