Cancer Patients to Get Blood Transfusions Made From Their Own Skin

blood_transfusion

Medical breakthrough for cancer patients

Patients could soon be transfused with blood made from their own skin in a breakthrough that could revolutionise cancer treatments and solve the blood donor shortage. Scientists have shown that ordinary skin cells can effectively be converted into adult blood cells in the laboratory.

Plant’s Light Switch Can Control Cells

If only we could control our own with just a flip of a switch

Chandra Tucker shines a blue light on yeast and mammalian cells in her Duke University lab and the edges of them start to glow. The effect is the result of a light-activated switch from a plant that has been inserted into the cell.

New Fertility Treatment to Turn Back Biological Clock

biological_clock

New technique turns biological clock back.

A new fertility technique could herald the end of the ‘ biological clock — by allowing women to have babies well into their 50s and 60s.  The treatment, to be unveiled at the World Congress of Fertility and Sterility conference in Munich, Germany, uses injections of stem cells to restore egg production.

Medical Breakthrough as Scientists Create Tiny Ear Hairs From Stem Cells to Cure Deafness

deafness

Scientists perfected turning stem cells into the delicate hairs found in the inner ear.

A cure for deafness could be on the horizon after scientists created specialised ear cells in the lab. Grown in their thousands, the delicate hairs could one day be transplanted into the inner ear, restoring hearing to millions.

Scientists Learning To Grow Custom-Size Bone Implants

novelties

Researchers use a bioreactor, left, to house and help cultivate material, right, that evolves into a bone.

If a lover breaks your heart, tissue engineers can’t fix it. But if sticks and stones break your bones, scientists may be able to grow custom-size replacements.  Gordana Vunjak-Novakovic, a professor of biomedical engineering at Columbia University, has solved one of many problems on the way to successful bone implants: how to grow new bones in the anatomical shape of the original.

Picasso’s Le Rêve painting, as seen through the eyes of a person with age-related macular degeneration.

An international research team led by Columbia University Medical Center successfully used mouse embryonic stem cells to replace diseased retinal cells and restore sight in a mouse model of retinitis pigmentosa. This strategy could potentially become a new treatment for retinitis pigmentosa, a leading cause of blindness that affects approximately one in 3,000 to 4,000 people, or 1.5 million people worldwide.
