Stem Cells: Scientific Progress and Future Research Directions

In February 2001 the Secretary of Health and Human Services requested that the National Institutes of Health prepare a summary report on the state of the science on stem cells. This report was developed in response to his request. It provides the current information about the biology of stem cells derived from all sources—embryo, fetal tissue, and adult. Since 1998, when human pluripotent stem cells were first isolated, research on stem cells has received much public attention, both because of its extraordinary promise and because of relevant legal and ethical issues. Underlying this recent public scrutiny is decades of painstaking work by scientists in many fields, who have been deciphering some of the most fundamental questions about life with the goal of improving health. In the last several decades, investments in basic research have yielded extensive knowledge about the many and complex processes involved in the development of an organism, including the control of cellular development. But many questions remain. How does a single cell—the fertilized egg—give rise to a complex, multi-cellular organism? The question represents a fundamental challenge in developmental biology. Researchers are now seeking to understand in greater detail the genetic factors that regulate cell differentiation in early development. Put simply, stem cells are self-renewing, unspecialized cells that can give rise to multiple types all of specialized cells of the body. The process by which dividing, unspecialized cells are equipped to perform specific functions—muscle contraction or nerve cell communication, for example—is called differentiation, and is fundamental to the development of the mature organism. It is now known that stem cells, in various forms, can be obtained from the embryo, the fetus, and the adult. The report is a review of the state of the science of stem cell research as of June 17, 2001. Included in this report is subject matter addressing stem cells from adult, fetal tissue, and embryonic sources. Because so much of the progress made to date was dependent on animal models, a significant emphasis is placed on understandings gained from mouse models of development and mouse stem cell research. The report also devotes substantial attention to scientific publications on the characterization of specialized cells developed from embryonic stem cells and the plasticity of adult stem cells. Both scientific and lay publications use a variety of terms to describe stem cells and their properties. For this reason, this report adopts a lexicon of terms and it is used consistently throughout. In several places in the report, discovery timelines are provided. The various sources of stem cells are described, as are the techniques used to isolate and develop them. A comprehensive listing of various stem cell isolation and characterizations is also included. In order to ensure the reader is provided information both about the basic biology of stem cells, and their therapeutic potential, the report contains several chapters focused on particular diseases which might benefit from stem cell research. These chapters on the use of hematopoietic stem cells, followed by focus features on specific nervous system diseases, diabetes, heart disease, and autoimmune diseases serve merely as examples of the many applications of stem cells that are being pursued. Also included are features that review aspects of stem cells as therapeutic delivery tools for gene therapy and, importantly, the safety considerations for developing stem cell-based therapies.

Vital Nutrients – Aller-C (Quercetin, Vitamin C, and Bioflavonoids) – Respiratory & Sinus Support – Gluten Free – 200 Vegetarian Capsules per Bottle

ALLER-C is a potent and effective combination formula. Quercetin and Hesperidin (from Citrus Bioflavonoids) have been shown to be two of the most useful and physiologically active flavonoids. This formula can be used for maintaining and supporting proper levels of enzymes and physiologic factors necessary for normal respiratory and sinus function. Vital Nutrients mission is to manufacture superior quality nutraceuticals that exceed both industry and government standards and provide clinically effective results. They provide over 200 science-based and clinically effective products. They have a comprehensive quality assurance program to ensure that purity and potency is consistently met on every product that they manufacture. Vital Nutrients uses independent U.S. ethical laboratories to test all raw materials and finished products. Each raw material is tested, regardless of origin, for purity and potency. All finished products are tested through a real time stability protocol for expiration date validation. They are an FDA Inspected facility that exceeds FDA cGMPs, and a member of the NPA.

Product Features

  • PROMOTES ALLERGY SYMPTOM RELIEF: Aller-C supports respiratory & sinus relief from nasal congestion or other allergy symptoms.* This non-drowsy formula is intended to help maintain normal function and wellness.*
  • CONTAINS QUERCETIN AND BROMELAIN: Quercetin is a natural bioflavonoid that supports healthy histamine levels and supports immune function. Bromelain is a proteolytic enzyme sourced from pineapple stem which helps promote normal drainage of waste products of inflammation.*
  • SUPPORTS HEALTHY IMMUNE SYSTEM: Aller-C acts as a mast cell stabilizer, which helps support a normal immune response.*
  • DOES NOT CONTAIN: This product is free from coatings, binders, gluten (wheat, rye, barley)*, milk/dairy (casein, whey)*, soy protein*, egg protein*, sugar. *Verified by independent testing
  • 100% TESTED INGREDIENTS: Since 2007, the FDA has mandated that supplement manufacturers test their ingredients and products. However, it allows manufacturers to perform minimal testing called “skip lot testing” meaning only a fraction of the ingredients are tested. VITAL NUTRIENTS has always exceeded these testing requirements by performing hundreds of tests on all raw materials and finished products at certified U.S. labs, allowing us to minimize potential risk of harm to the consumer.
