1. Electrical map of the heart to aid Stem cell therapy for angina

As a novel approach to treat Angina, researchers have used the electrical map of the heart to locate the areas in the heart that are not getting enough blood supply so that stem cells can be injected via a catheter to aid repair of these spots of the heart Click to read more...

2. "Stem cell induced scarring in spinal cord injury blocks damage and helps in nerve cell recovery – reveals study"

The stem cells serve as the main source of the scar tissue formed after spinal cord injury. It has now been identified that this scar tissue is necessary for stabilizing the injury and preventing it from spreading. Also scar tissue facilitates the survival of the damaged nerve cells.

3. Sweat gland stem cells with the ability to regenerate the skin, discovered

University of Southern California researchers have worked on sweat gland stem cells and proven that these sweat gland stem cells not only regenerate their own cells but under certain conditions can heal skin wounds and regenerate all the layers of the epidermis.Click to read more...

4. Role of Oct4 in linking embryonic stem cell adhesion and migration to progenitor maintenance explored

In a recent study published, the role of Oct4 in making embryonic stem cells adhere to one another and thereby helping in maintaining their progenitor stage has been explored. This study will pave way for efficient way of maintaining stem cells as stem cells.Click to read more...

5. Scientists uncover Cellular signaling pathway that converts healthy mesenchymal stem cells in the jaw to cells with the ability to form tumour

Researchers have uncovered a cellular signaling pathway which converts the mesenchymal stem cells in the jaw into cells that give rise to ossifying fibroma (a type of tumour of the jaws). These converted cells have lessened ability to make healthy bone tissue and their multiplication rate is also greatly increased. Click to read more...

6. Stem cells from fat tissue of obese women contribute more actively to growth of cancer – identifies study

A team of scientists have investigated the behavior of stem cells isolated from the liposucted fat tissue samples of lean and obese patients and have identified that the stem cells from morbidly obese patients were greatly invasive than those from lean patients and they contributed more actively to tumour growth. Click to read more...

7. Role of a specialized type of brain cell in maintenance of neurogenesis from stem cells in brain deciphered

It has been identified in a mice study that when a type of brain cells called parvalbumin-expressing interneurons release the chemical signal GABA, the nearby neurons survived in greater numbers while the nearby stem cells become dormant. Click to read more...

8. Reactivating Lin28a gene can help in regeneration of tissues by acting on cellular metabolism

A study has suggested that by reactivating a dormant gene called Lin28a it is possible to regrow hair and repair cartilage, bone, skin and other soft tissues in a mouse model and this tissue repair is done by Lin28a by enhancing the cellular metabolism. Click to read more...

9. Stem cells from intestine grown in novel scaffold –breakthrough study with potential to treat Hirschsprung's Disease

As a potential cell therapy option for Hirschsprung's disease, researchers have grown stem cells from the intestine in a novel scaffold which can help in the optimal regeneration of the neurons after transplantation of the cells in the affected part of the intestine. Click to read more...

10. Induced pluripotent stem cells can self-correct certain specific genetic defects- astonishing discovery

While studying induced pluripotent stem (iPS) cells from patients with a brain disorder called Miller-Dieker syndrome, sceintists have stumbled upon the discovery that iPS cells can self correct certain genetic abnormaities like the ring chromosome abnormalities. Click to read more.

Really???

1. Are you aware about the organism called Tetrahymena thermophila that exists in 7 different sexes i.e mating types which can reproduce in 21 different combinations and each organism will decide which sex it will become through a stochastic process during mating? (Source: Wikipedia).

2. Did you know what Uniparental parthenotes are? In some species, when the entire genome of the embryo is maternal origin, the embryo is termed as uniparental parthenote and when paternal, it is termed uniparental androgenote. Though such parthenotes are not possible normally in mammals, spontaneous activation of unfertilized oocytes implicated as a cause of ovarian teratoma does occur rarely in humans. Recently Uniparental parthenogenetic stem cells (PSCs) have been developed using in vitro activation of oocytes from mice and have been applied for cardiac repair.
