World’s first man-made organ transplant carried out in Sweden

Windpipe

An image released by Karolinska University Hospital shows part of the operation.

The world’s first transplant of a fully synthetic organ has been carried out by surgeons – a windpipe created using the patient’s stem cells and an artificial “scaffold”.  A month ago a 36-year-old cancer patient received the organ at the Karolinska University Hospital in Stockholm.

Scientists discover protein to restore grey hair to it’s original color

grey hair

The discovery raises the prospects of drugs, lotions or shampoos that raise levels of wnt – and restore white or grey hair to its natural color.

Scientists have got to the root of grey hair – paving the way for locks that retain the luster of their youth well into old age.

Scientists Develop Pill to Mend Broken Heart

heart attack

Taking the pill when a heart attack occurs, the muscles and blood vessels around the organ could rebuild themselves.

Researchers in Britain claim they may be just a decade away from perfecting a way to persuade the heart to rejuvenate – a process thought to be impossible just five years ago.  They have developed a pill that triggers the heart to repair itself after an attack and is a major step towards one of the “holy grails” of medical research.

Chemical Discovered Which ‘Makes Bone Marrow Repair Skin’

skin graft 234

Skin grafts trigger repair by bone marrow cells.

The chemical which summons stem cells from bone marrow to the site of a wound has been discovered by scientists in the UK and Japan.

The study, published in Proceedings of the National Academy of Sciences, identified the distress signal – HMGB1.

The authors believe it can be used to put “a megaphone in the system” to improve the treatment of injuries such as burns and leg ulcers…

Cancer cell

A joint team of Indian and Australian scientists claims to have achieved a breakthrough by creating an antibody which could be used for developing a “medical smart bomb” that would help seek out and eradicate the root of cancer — the stem cells.

German Doctors Claim They Have Cured a Patient’s HIV Via Stem Cell Transplant

HIV-1 particles assembling at the surface of an infected macrophage.

A huge story with implications that aren’t all immediately clear is emerging in Berlin this week: doctors treating an HIV-infected with leukemia believe they have, in a roundabout way, cured his HIV infection via a stem cell transplant containing cells that happened to be impervious to HIV infection. And while the story by no means indicates that a cure for HIV has been discovered, the unexpected finding certainly opens the door to further review and great optimism in a frustrating battle that has now spanned several decades.

Gene Therapy for Metastatic Melanoma?

DO NOT DRINK… Trust me, i know what its made of!

A potent anti-tumor gene introduced into mice with metastatic melanoma has resulted in permanent immune reconfiguration and produced a complete remission of their cancer, according to an article to be published in the December 2010 issue of the Journal of Clinical Investigation.

Bioengineers and the latest Adult Stem Cells Breakthrough!

Finally, the perfect environment provided for stem cell research!

Bioengineers from the University of California, San Diego have achieved the “Triple Crown” of stem cell culture — they created an artificial environment for stem cells that simultaneously provides the chemical, mechanical and electrical cues necessary for stem cell growth and differentiation.

Belly Fat Actually Helps Heart Attack Patients: Study

fat-belly

“Spare tire” could save lives.

Stem cells taken from waistline fat could be used as a treatment for heart attacks. Scientists injected stem cells derived from waistline fat tissue into the hearts of coronary patients and found the cells reduced levels of damage, increased blood flow and improved the organs’ pumping ability.

Embryonic stem cells under microscope

Growing human embryonic stem cells in the lab is no small feat. Culturing the finicky, shape-shifting cells is labor intensive and, in some ways, more art than exact science. Continue reading… “Embryonic Stem Cell Culturing Grows from Art to Science”

Modeling Autism in a Lab Dish…

A striking resemblance to Jim Carrey… Or is it?

A collaborative effort between researchers at the Salk Institute for Biological Studies and the University of California, San Diego, successfully used human induced pluripotent stem (iPS) cells derived from patients with Rett syndrome to replicate autism in the lab and study the molecular pathogenesis of the disease.
