Doctors use stem cell method to regrow teeth in children

Don’t worry about your child’s loss of teeth or if they have immature ones as doctors at AIIMS can regrow them using stem cell technique by just making a minute slit in their root.
“We at AIIMS are treating children with infected, immature teeth as a result of traumatic injuries, by using locally available indigenous stem cells,” Dr Naseem Shah, Chief of the Centre for Dental Education and Research, AIIMS said.

She explained that the root forms the most important part of the tooth. It anchors the tooth within the bone and houses the pulp (tiny blood vessels and nerves) which

Stem Cell Therapy is Reality

The mesenchymal stem cells found in the bone marrow can give rise to bone, fat, and muscle tissue, and have been used in hundreds of clinical trials for tissue repair.

Unfortunately, the results of these trials have been underwhelming, the main problem being that these stem cells do not stick around in the body long enough to benefit the patient.

Researchers have now found that transplanting mesenchymal stem cells along with blood vessel-forming cells naturally found in circulation improves results.

Human Heart Can Make New Cells – Discovery could lead to ways of regrowing damaged cardiac tissue

Solving a longstanding mystery, scientists have found that the human heart continues to generate new cardiac cells throughout the life span, although the rate of new cell production slows with age.
The finding, published in the April 3 issue of Science, could open a new path for the treatment of heart diseases such as heart failure and heart attack, experts say.

“We find that the beating cells in the heart, cardiomyocytes, are renewed,” said lead researcher Dr. Jonas Frisen, a professor of stem cell research at the Karolinska Institute in Stockholm, Sweden. “It has previously not been known whether

‘Leftover’ veins from heart surgery yield stem cells

A University of Bristol team extracted stem cells from the veins, then used them to stimulate new blood vessel growth in mice, Circulation reports.

The researchers say their findings could bring treatments to repair damaged heart muscle one step closer.

However, a stem cell expert warned that they remained some years away.

Stem cells are attractive to medical researchers because they have the ability to produce many different types of human cell, opening up the possibility of repair or renewal for tissues ravaged by disease or injury (…)

Stem Cells Transplanted From Marrow Into Heart May Improve Heart’s Performance

Concha Herrera Arroyo, from El Pais

The Cardiology department and the Area of Cell Therapy of Cordoba hospital Reina Sofia are carrying out clinical tests with patients who have suffered from a severe heart attack. With the implantation of the patient’s stem cells, the heart regenerates thus improving its wall motion, that is, its cardiac performance.

Indeed for the last four years, the Area of Cell Therapy of Cordoba hospital, led by haematologist Dr. Concha Herrera, has been implementing a therapy program with adult stem cells in patients with heart-related problems. However, this therapy is not a service the hospital
