Understanding Stem Cells

“For centuries, scientists have known that certain animals can regenerate missing parts of their bodies. Humans actually share this ability with animals like the starfish and the newt. Although we can’t replace a missing leg or a finger, our bodies are constantly regenerating blood, skin, and other tissues.

The identity of the powerful cells that allow us to regenerate some tissues was first revealed when experiments with bone marrow in the 1950s established the existence of stem cells in our bodies and led to the development of bone marrow transplantation, a therapy now widely used in medicine.

This discovery raised

On Sept. 14, 46-year-old Hatem Faraj suffered a major heart attack while watching Monday Night Football on TV.
Tuesday, the Wesley Chapel man joined the cutting edge of heart disease research, becoming the area’s first participant in a study to see if a patient’s own stem cells can regenerate his damaged heart muscle.

The procedure he had at Pepin Heart at University Community Hospital in Tampa is part of a University of Florida research program. Its aim is improving chances of long-term survival and reducing heart transplants. Using stem cells to regenerate heart tissue has been studied for several

Stem Cells used to Grow Bone in Boy’s Jowl

Cincinnati Children’s Hospital Medical Center, known for “miracle” surgeries, has completed a medically historic procedure where doctors used stem cells taken from the fat tissue of a 14-year-old boy and combined them with growth protein and donor tissue to grow viable cheek bones in the teen.

Brad Guilkey, 15, suffers from a rare kind of genetic disorder known as Treacher Collins Syndrome, where the bones and other tissues are prevented to develop in the face (…)

The medical team implanted cadaver bone into Brad’s face in May, and then they injected his own stem cells into the donor bone to fill

A 21-year-old leukemia patient underwent pioneering surgery in a Shanghai hospital Wednesday, when doctors transfused 30 milliliters of umbilical-cord blood donated by a Shanghai cord bank. Today they will transplant a batch of his father’s stem cells, which are an imperfect match.

This combination of umbilical-cord blood and half-matched stem cells can offer lifesaving transplant opportunities to many more patients than traditional methods, which require a perfect match between patient and donor, said doctors from Shanghai No. 1 People’s Hospital.

It will be a month before results of the transplant are determined.

About 40,000 to 50,000
