GENE THERAPY AND STEM CELLS SAVE LIMB

Gregg Semenza, M.D., Ph.D.

Blood vessel blockage, a common condition in old age or diabetes, leads to low blood flow and results in low oxygen, which can kill cells and tissues. Such blockages can require amputation resulting in loss of limbs. Now, using mice as their model, researchers at Johns Hopkins have developed therapies that increase blood flow, improve movement and decrease tissue death and the need for amputation. The findings, published online last week in the early edition of the Proceedings of the National Academy of Sciences, hold promise for developing clinical therapies.

Adult Stem Cells Rebuild Broken Jawbone

Stem Cell Research Brings About Another Miracle
Korean doctors have apparently regrown a patient’s jawbone using the patient’s own Adult Stem Cells in yet another amazing miracle that Adult Stem Cell research has brought us.
An 18 year old Korean boy who had to have most of his jawbone and his teeth removed due to a tumor […]

Banking cord blood presents dilemma for new parents

Expectant parents must make several important medical decisions. Among them: whether to have prenatal genetic testing, request pain medication during labor, strive for a natural birth or circumcise a male baby?
Perhaps one of the most overlooked parts of childbirth preparation is whether to save or donate the infant’s umbilical cord blood.

Umbilical cords are usually discarded as medical waste. But the potential uses for cord blood are growing, making it imperative that families understand their options, including whether to pay to have the blood stored for possible use in the event of their child’s illness

I grew my own facelift… and it took an inch off my tummy

(…) Three months ago the world’s first cosmetic stem-cell facelift was carried out on Pauline Wills, 55, an office manager from South London, by Dr Aamer Khan from the Harley Street Medical Skin Clinic. It cost £7,500, took nearly six hours under local anaesthetic and Pauline had the added bonus of losing an inch from her tummy.

And because the procedure uses the body’s own stem cells – which makes it a living tissue graft – you grow into your own facelift during the six months afterwards (…)

Stem cells are present throughout the body and one of their functions is

First Stem Cell Drug Fails 2 Late-Stage Clinical Trials

What might become the first drug derived from human stem cells failed in two late-stage clinical trials, dealing a setback to the drug’s developer and to the stem cell field (…)

Prochymal is a preparation of mesenchymal stem cells, which are obtained from the bone marrow of healthy young adults.
Because the cells are derived from adults, they sidestep the ethical issues stemming from the destruction of human embryos needed to make embryonic stem cells. Unlike most other types of adult stem cells, mesenchymal cells grow well in culture, so thousands of doses can be produced from a single donation.

Stem cells,
