Multipotent hemopoietic stem cells (MHSC) are found in the bone marrow. These precursor cells are responsible for the continuing formation of our blood cells, including our immune system leukocytes (white blood cells). Leukocytes include monocytes, macrophages, neutrophils, basophils and eosinophils.

Loss of vision is the second greatest fear, next to death, among the elderly. Age related cataracts are one of the major causes of loss of vision worldwide. Approximately 20 million people in the United States have their vision obstructed by cataracts and 500,000 new cases are diagnosed annually.

Our genes are formed from microscopic double-strands of deoxyribonucleic acid (DNA). They are dependent on adequate nutrition for their structure and activity. By appropriately switching on and off (this is called transcription in the genome research world) our genes direct the behavior of our body's 60 trillion cells. Many genetic researchers consider our genes to be the Rosetta stone of health and disease.

"There are three topics in modern science that have caused more controversy than stem cells " the development of nuclear bombs, the notion that the sun is at the center of our solar system and the theory of evolution," so says Michael Stebbins, PhD, the director of biology policy for the Federation of American Scientists and a former US congressional fellow in science policy.

Scientific evidence, as well as common sense, is mounting regarding the need for daily intake of the full-spectrum of micronutrients to protect eye health, in spite of the huge amount of B&L marketing dollars spent advertising the simplistic ARED formulation, which includes questionable amounts of beta-carotene and zinc.

For optimal health of the whole body, including the eyes, the consumption of two or more servings of fish high in Omega-3 fatty acids per week is advocated by the American Heart Association, the American Medical Association, the FDA and the most recent edition of the peer-reviewed journal, Ophthalmology. However, fresh wat

A large body of literature suggests the retina experiences increased oxidative stress in diabetes. Overproduction of superoxide by the mitochondrial electron transport chain activates nuclear transcription factors (NFkB) and the three major pathways postulated to be involved in the pathogenesis associated with retinal capillary cell apoptosis in diabetic retinopathy.

An important study published in the American Journal of Epidemiology suggested that smokers who consume a wide variety of dietary antioxidants, including small amounts of natural beta carotene, have a substantially lower risk of developing lung cancer. This was not good news to the vitamin companies who aggressively market beta-carotene free "Smokers" AMD formulations.

Mitochondria are the most complex organelles in the cell; they provide energy for all basic metabolic processes including those associated with the retina. They detoxify oxygen, function in calcium and iron homeostasis, and they play a key role in programmed cell death. Oxygen (free radical) damage is produced as an inevitable byproduct of mitochondria function. Mitochondria are particularly vulnerable to this damage as they contain their own DNA.
