CUBA INVENTS CANCER VACCINE

Cuban Cigars Cure Stem Cells Treatments

CUBAN CIGARS CURE CANCER WITH STEM CELLS VACCINE

Cuba has launched the worlds first Cancer Vaccine. Cuba's famous Cohibas Cigars are known for exporting stem cells, but it might soon be known for exporting a lung cancer vaccine produced by natural stem cells that researchers say can turn advanced lung cancer into a manageable chronic illness that can extend a cancer patients life span by 25% of more.

Cuba is famous for the quality of its Cohiba cigars comes some pretty big news. Granma reports that Cuban stem cell medical authorities have released the first therapeutic vaccine for terminal lung cancer. CimaVax-EGF is the result of a 30 year stem cell research project at CHCMI, Havana’s Center for Molecular Immunology, and it could make a dramatic difference for patients dying from late-stage lung cancer.
Cuban Stem Cell Scientist
Cuban stem cell scientist have invented a new vaccine called "CimaVax-EGF" which isn’t a vaccine in the preventative sense. EGF stem cells doesn’t prevent lung cancer from taking hold in new patients. It’s based on a new types of stem cells related to uncontrolled cell growth deviation that doesn’t prevent cancer from starting in the first place but attacks the cells that does damage your own lung cells

Cuban Stem Cells Reasearch,
Stem cells, cancer vaccines, Cuba, health, lung cancer, vaccines and more
Stem cells research into Cuban vaccines can turn aggressive final stage lung cancer into a controllable chronic disease by helping your own body produce its own stem cell antibodies that battle agaionst the same proteins that cause uncontrolled cell growth destruction. Even Chemotherapy and radiotherapy are still popular to destroying cancer cells showing no improvement to the new stem cells and new vaccine which could be a lifesaver for a terminal cancer patient..
Free Cuban Stem Cells
This new Cuban Stem cell vaccine has already been tested in thousands of patients in Havana Cuba and is being distributed throughout Cuban hospitals free of charge. That’s huge health care benifit for Cubans where smoking Cohiba cigars is part of Cuba's national pastime and a leading cause of Cancer deaths. If Cuban cigar smoking stem cell vaccines are proven successful then Cuba should give all those Americans suffering from lung cancer reason to rejoice with a good tasting Cohiba Cuban cigar courtesy of the new Cuban Stem cell Vaccine.

STEM CELLS REPAIR EYES

Eye Damage Repaired Using Stem Cells

Stem Cell Treatments Repair Eye Damage

Severe Eye Damage Cured by Stem Cells

Dozens of people who were blinded or otherwise suffered severe eye damage when they were splashed with caustic chemicals had their sight restored with transplants of their own stem cells, Italian researchers reported Wednesday.

The treatment worked completely in 82 of 107 eyes and partially in 14 others, with benefits lasting as long as a decade so far. One man whose eyes were severely damaged more than 60 years ago now has near-normal vision.

Sight regained

Currently, people with eye burns can get an artificial cornea, a procedure that carries such complications as infection and glaucoma, or they can receive a transplant using stem cells from a cadaver, but that requires taking drugs to prevent rejection.

The Italian study involved 106 patients treated between 1998 and 2007. Most had extensive damage in one eye, and some had such limited vision that they could only sense light, count fingers or perceive hand motions. Many had been blind for years and had had unsuccessful operations to restore their vision.

The cells were taken from the limbus, the rim around the cornea, the clear window that covers the coloured part of the eye. In a normal eye, stem cells in the limbus are like factories, churning out new cells to replace dead corneal cells. When an injury kills off the stem cells, scar tissue forms over the cornea, clouding vision and causing blindness.

In the Italian study, the doctors removed scar tissue over the cornea and glued the laboratory-grown stem cells over the injured eye. In cases in which both eyes were damaged by burns, cells were taken from an unaffected part of the limbus.

Researchers followed the patients for an average of three years and some as long as a decade. More than three-quarters regained sight after the transplant. An additional 13 per cent were considered a partial success. Though their vision improved, they still had some cloudiness in the cornea.

Patients with superficial damage were able to see within one to two months. Those with more extensive injuries took several months longer.

"They were incredibly happy. Some said it was a miracle," said one of the study leaders, Graziella Pellegrini of the University of Modena's Center for Regenerative Medicine in Italy. "It was not a miracle. It was simply a technique."

The study was partly funded by the Italian government.

STEM CELLS. WHY ARE THEY IMPORTANT

Image via WikipediaWHY ARE STEM CELLS IMPORTANT

STEM CELLS have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition, in many tissues they serve as a sort of internal repair system, dividing essentially without limit to replenish other cells as long as the person or animal is still alive. When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell.

Stem cells are distinguished from other cell types by two important characteristics. First, they are specialized cells capable of renewing themselves through cell division, sometimes after long periods of inactivity. Second, under certain physiologic or experimental conditions, they can be induced to become tissue- or organ-specific cells with special functions. In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. In other organs, however, such as the pancreas and the heart, stem cells only divide under special conditions.

Until recently, scientists primarily worked with two kinds of stem cells from animals and humans: embryonic stem cells and non-embryonic "somatic" or "adult" stem cells. The functions and characteristics of these cells will be explained in this document. Scientists discovered ways to derive embryonic stem cells from early mouse embryos nearly 30 years ago, in 1981. The detailed study of the biology of mouse stem cells led to the discovery, in 1998, of a method to derive stem cells from human embryos and grow the cells in the laboratory. These cells are called human embryonic stem cells. The embryos used in these studies were created for reproductive purposes through in vitro fertilization procedures. When they were no longer needed for that purpose, they were donated for research with the informed consent of the donor. In 2006, researchers made another breakthrough by identifying conditions that would allow some specialized adult cells to be "reprogrammed" genetically to assume a stem cell-like state. This new type of stem cell, called induced plenipotentiary stem cells , will be discussed in a later section of this document.

Stem cells are important for living organisms for many reasons. In the 3- to 5-day-old embryo, called a blastocyst, the inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lung, skin, sperm, eggs and other tissues. In some adult tissues, such as bone marrow, muscle, and brain, discrete populations of adult stem cells generate replacements for cells that are lost through normal wear and tear, injury, or disease.

Given their unique regenerative abilities, stem cells offer new potentials for treating diseases such as diabetes, and heart disease. However, much work remains to be done in the laboratory and the clinic to understand how to use these cells for cell-based therapies to treat disease, which is also referred to as regenerative or reparation medicine.

Laboratory studies of stem cells enable scientists to learn about the cells’ essential properties and what makes them different from specialized cell types. Scientists are already using stem cells in the laboratory to screen new drugs and to develop model systems to study normal growth and identify the causes of birth defects.

Research on stem cells continues to advance knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. Stem cell research is one of the most fascinating areas of contemporary biology, but, as with many expanding fields of scientific inquiry, research on stem cells raises scientific questions as rapidly as it generates new discoveries.

European Stem Cell Trails Successful

Image via Wikipedia

Europe Treats Stem Cells

A new medical process designed to stop the damage caused by a degenerative eye disease is to be tested in Europe's first clinical trial using embryonic stem cells.

If it proves to be successful, the treatment will open up a wide range of possible treatments for eye diseases and would be a huge boost for medicine because stem cells are thought to hold the key to tackling many types of disease.

Twelve volunteer patients suffering from Stargardt's macular dystrophy, which is know as incurable and happens in childhood, will have stem cells injected directly into their eyes to test the validity of the procedure.

Embryonic stem cells are know as "master cells" which have the potential to develop into

many different types of stem cells.

The trial is being held by Moorfields Eye Hospital and will be led by Professor James Bainbridge, who said: "This is the first time embryonic stem cells have been used here. They have great potential to be able to regenerate a variety of different tissues and organs. It's very exciting now to be at the stage where we can begin to explore that potential."

If they are as successful as researchers hope they will be, a treatment based on the trials may be available in five to 10 years

Stem Cells China

Stem Cells In China

When it comes to stem cells, China is showing that it can perform a world-class science. It is a shame that fraud happens and that the people in power turns a blind eye

Jan 14th 2010 | BEIJING | from the print edition

Illustration by David Simonds

IN THE West, and particularly in the United states, the phrase “stem cell” has a faile bad reputation. Stem cells are associated, in the minds of many, with the killing of human embryos, the cloning of humans and the Frankenstein-like creation of human body parts. Add in the strange case of Hwang Woo-suk, a South Korean researcher who announced, to great acclaim, that he had success in cloning human embryos and was then exposed as a fraud, and you have an area in which many researchers understandably fear to tread.

But not Chinese researchers. A rejection of the idea that embryos are in any meaningful sense human beings, together with the possibility of stealing a march on the diffident West, has caused a lot of research into stem cells in China. And not only research. Chinese clinics have moved onto offering therapies. Patients from around the world fly in for the treatment of conditions ranging from autism to spinal-cord injury.

A stem cell is one that, when it divides, has the potential to generate specialised cell types through one daughter line while the other daughter retains the property of “stemness”. Some stem cells, known as pluripotent cells, can generate several different cell types. The pluripotent cells found in embryos, for example, can turn into any one of the 220 or so cell types of which a human body is formed.

A potent mix

Many hospitals are making a profit from unproven therapies, but many proper clinical trials are also being conducted using stem cells, for conditions like heart-muscle damage, ischemia of the limbs, liver disease and neurological disorders. These include a multi-centre trial organised by the China Spinal Cord Injury Network, a consortium of over two dozen centres in mainland China, Hong Kong and Taiwan, to test whether a combination of lithium and transplants of stem cells from umbilical-cord blood could lead to improvements in patients with spinal-cord injury.

Moreover, last year researchers at the Chinese Academy of Sciences, in Beijing, and Shanghai Jiao Tong University dispelled some of the voodoo surrounding stem cells by producing fertile mice from inducible pluripotent cells. An inducible pluripotent cell is one derived from a body cell (skin, for example) that has been made pluripotent by chemical treatment, rather than having been extracted from an embryo. Besides saving embryos, that means (if the same trick can be repeated in humans) that replacement organs might be grown from a patient’s own tissues.

This is all very encouraging. China’s health ministry has, however, turned a blind eye to the unauthorised stem-cell therapies under its juristrict.

STEM CELLS HEALING POWER

How Stem Cells Heal Humans

When stem cells are injected into the blood stream, into your muscles, they travel to parts of the body that have suffered from an injury. At these various sites of injury, the blood vessels have been damaged, narrowed and constricted. These constrictions prevent the oxygen carrying red blood cells from going in to the tissues - which then produce places of reduced oxygen content. Since stem cells are big, they become lodged in these tight and constricted small blood vessels. The low levels of oxygen found in these damaged areas are just what the stem cells need to improve and grow.
As the stem cells grow in the damaged areas, they gradually become influenced by their surrounding cells and environment to become new cells similar to those cells they come in contact with. As they grow and become specific, they are able to transform into new veins, neurons, , bone marrow, muscle, eye, liver, kidney, etc., depending on the area where they are injected.
In the first stages of human development prior to the first cells becoming specialized, the stem cells develop best in environment with low oxygen. As the embryo grows and the stem cells become specific, they begin to require more oxygen. The more specialized, the more oxygen they need. For example, the brain is the most specialized organ of the body, using 20% of the oxygen consumed by the body while only being two percent of total body weight.
Whether the health challenge is Alzheimer's Disease, Stroke, head/brain Injury, Spine Injuries, Heart Problems, Diabetes, Parkinson's Disease, Cancer, Blindness, or any genetic/muscular abnormalities, the results of many human and animal studies using human umbilical cord stem cell treatments are very promising and a look into the future.

HISTORY OF STEM CELLS

WHAT ARE STEM CELLS?

Image via WikipediaWHAT ARE STEM CELLS?

Stem Cells are the basic building blocks of all life including structure and function of every human being on earth, every animal, and any other living being. Stem cells can carry oxygen, nutrients and anything that the human body, and brain needs to survive.

Stem Cells are one of the smallest units required for all living humans. These Cells basically control your bodies entire internal health management system.

There are vast variety of cells but the most useful are animal cells and plant cells. Stem cells have cellular walls, can reproduce and come in many different sizes, shapes and can do many different functions for Human bodies.

STEM CELLS THERAPY

Stem Cells can be tricked into forming any part of the human body including heart, brain, hips, knees, bones, spinal cord, cartridge, nerves, lungs, liver and any other organ. Using today's stem cell technology doctors across the world are changing the way medicine is being used to treat all kinds of diseases including stroke, arthritis, diabetes, baldness, blindness, scoliosis, spinal cord injury, bone marrow, Alzheimer, Parkinson, and even cancer.

The worlds leading Stem Cell experts are predicting that today advanced stem cell therapy research will eventually lead to the complete reversing of the human aging process.
