Overcoming aging-caused difficulties in salivary gland

Stem cells are the cells that are responsible for the maintenance of tissues and organs by replacing functional cells with a limited life-span or that are damaged beyond repair. Over the last decades stem cells have been

Small molecule antagonists maintain stem cell potency

The decision for a stem cell to make an exact copy of itself and maintain the same level of potency versus initiate a differentiation program is critical both during development and normal tissue maintenance. CBP and p300

The interplay of the ticking clock and miRNA in differentiation of endothelial precursors

Our day-today activities like sleep-wake cycle, hormone release, body temperature and other important bodily functions follow a characteristic rhythm over 24 hours called a circadian rhythm. A ‘master clock’ in brain termed as suprachiasmatic nucleus (SCN) co-ordinates

Cardiac atrial appendage stem cells: bright cells for a bright future for patients with ischemic heart disease

Ischemic heart disease is still one of the major causes of global morbidity and mortality. Although significant improvements in medical and surgical treatments have been accomplished over the last few decades, these are still not able to

The fossil viruses from within that shape evolution

Our genome contains a colossal amount of virus-related sequences. Over 4 million fragments of our DNA derive from mobile genetic elements, some of which once were viruses that infected the germ line (egg or sperm cells) of

Mitochondrial activity is different in different sub-regions of the human amniotic membrane

What is the first image a human being probably sees? Provided a fetus could see, it would see the inner lining of the uterus, the so called amniotic membrane. The amniotic membrane consists of two layers, the
