1. Teeth like structures grown using pluripotent cells from human urine in mice study

Chinese researchers have used pluripotent stem cells from urine that have the potential to form rudimentary teeth structures and when these cells were implanted into the kidneys of mice, the cells gave rise to a teeth like structure with dental pulp, dentin, enamel space and enamel organ.

2. Novel RNA based iPSC generation protocol to dramatically improve existing methods

An easily reproducible nonintegrating RNA-based method has been identified by scientists to reprogram adult cells into pluripotent stem cells and this method is expected to help improve the reprogramming technique to create induced pluripotent stem cells (iPSCs) without permanent genetic alterations in the future.

3. Study reveals that blood Stem cells in the bone marrow are turned off in acute myeloid leukemia (AML)

As a step forward in understanding Acute Myeloid Leukemia (AML), a type of blood cancer, it has been identified that the number of blood forming stem cells in the bone marrow remains the same in AML but the cancer turns them off by certain mechanisms so that these stem cells can't produce healthy blood cells.Click to read more...

4. Inducing intestinal stem cells using certain proteins help in protecting them against high dose chemotherapy- reports study

A study on mice has shown that inducing the stem cells in the intestine using certain proteins helps turn on a biological mechanism which causes the intestinal stem cells to go to an overdrive for intestinal regeneration and repair which in turn helps in protecting these mice from lethal doses of chemotherapy.

5. System for mass production of pluripotent stem cell derived hepatocytes developed

Massoud Vosough and his team of researchers have described a system for mass manufacture of hepatocytes (liver cells) from human pluripotent stem cells and when they were transplanted to mice affected with acute liver injury, these liver cells functioned normally and improved the animals' survival.

6. New approach for mass production of cancer killing T cells

Using Induced Pluripotent stem cells, a new approach has been developed to create large numbers of 'Off-the-shelf-T-cells', engineered to target a particular cancer "antigen" or protein. Click to read more...

7. Human cartilage created in lab using 3D printing technology

3D printing technology and customized fabrication equipment has helped scientists from Melbourne to create human cartilage tissue from stem cells which in the future could form a potential therapeutic option for cartilage defects and injuries. Click to read more...

8. Gold nanoprobes to identify different types of stem cells – new technology breakthrough

Using a technology called Surface Enhanced Raman Spectroscopy (SERS), researchers have employed gold nano-probes to recognize the different types of stem cells with higher precision in vivo and this study forms a major breakthrough in Stem cell tracking inside the body. Click to read more...

9. Role of Cardiac stem cells in repair after heart failure demonstrated in novel study

The natural regenerative ability of a type of cardiac tissue resident stem cells in response to heart failure has been highlighted for the first time in a study on rodents by a team of researchers at King's College London. Click to read more...

10. Skin stem cell mapping reveals new knowledge on skin renewal mechanism

Through mapping of stem cells in the skin employing shining proteins a new mechanism model by which the skin renews itself has been identified and this model challenges our current understanding of the skin renewal mechanism. Click to read more..

1. Among serendipitous discoveries in Biology, the Pap Smear deserves mention. Dr. George Nicholas Papanicolaou who in 1923 was in the midst of a study observing cellular changes over the course of a menstrual cycle in the vaginal fluid of women was astonished to discover that in a smear of vaginal fluid from a woman with cervical cancer, abnormal cancer cells could be plainly observed under microscope. This discovery has helped change the lives of several millions of women worldwide using a simple non-invasive screening methodology for cervical cancer, 'the Pap Smear'.

2. Did you know that there exists nearly 33 major human blood group systems (including the AB and Rh systems) recognized by the International Society of Blood Transfusion (ISBT)? Many of the blood group systems have their names based on the name of the patients in whom the corresponding antibodies were first encountered.
