Study of Chlorophyll

Effect of dietary chlorophyll derivatives on mutagenesis and tumor cell growth

Chernomorsky S, Segelman A, Poretz RD. (1999). Teratog Carcinog Mutagen.19(5):313-22

Much attention in recent years has been given to the antigenotoxicity of chlorophyll. Chlorophyll, however, is known to be converted into pheophytin, pyropheophytin, and pheophorbide in processed vegetable food and following ingestion by humans. Studies were conducted on the antimutagenic and tumoricidal potencies of these compounds. All the chlorophyll derivatives tested exhibit identical antimutagenic effect towards 3-methylcholanthrene (3-MC), suggesting that the porphyrin nucleus may complex directly with the mutagen. It does not exclude, however, another mechanism of activity involving inactivation the enzymatic transformation of 3-MC. In contrast, the action of N’-nitro-N’-nitrosoguanidine (MNNG) depends upon structural differences between the chlorophyll derivatives. It is significantly lower when the phytol-containing pheophytin and pyropheophytin are tested as to that of the phytol-lacking pheophorbide. The higher concentrations of the chlorophyll derivatives were required to reduce the mutagenicity of MNNG than needed for 3-MC. The cytotoxicity of chlorophyll derivatives against tumor cells also was evaluated. The cellular uptake and inhibition of myeloma cell multiplicity were found to be greater for pheophorbide than for pheophytin. Calculated on the amount of cell associated chlorophyll derivative, however, pheophytin was more cytostatic/cytotoxic than pheophorbide. The results presented in this report indicate that food sources that yield chlorophyll derivatives may play a significant role in cancer prevention.

An Exciting New Discovery!

Recently the first stage of an extensive research project carried out at the Royal Victoria Hospital in Montreal, Canada produced some remarkable results. The project studies the effect of Aphanizomenon flos-aquae on the immune and endocrine systems, as well as on general blood physiology. It was discovered that eating AFA had a profound and unique effect on Natural Killer (NK) cells. The results were recently published under the title: Effects of the Blue Green Algae Aphanizomenon flos-aquae on Human Natural Killer Cells. It appears in Chapter 3.1 of the IBC Library Series, Volume 1911, Phytoceuticals: Examining the health benefit and pharmaceutical properties of natural antioxidants and phytochemicals.

NK cells have the ability to search for and recognize cells that are cancerous or have been infected by a virus, and kill them. The team of research scientists at the Royal Victoria Hospital, led by Dr. Gitte S. Jensen, discovered that eating Aphanizomenon flos-aquae triggers the movement of 40% of the circulating NK cells from the blood to the tissues where their main function is to perform immune surveillance and eliminate cancerous and virally-infected cells. Further research may prove that eating a small amount of AFA every day could assist in the prevention of cancer and viral infections. No other substance is known to trigger such a movement of NK cells in the body. This is very exciting news! We hope you will share it with everyone you know!_____________________________________________________

Abstract
Objective
The goal of this study was to evaluate effects on human stem cells in vitro and in vivo of an extract from the edible cyanobacterium Aphanizomenon flos-aquae (AFA) enriched for a novel ligand for human CD62L (L-selectin).

Experimental approach
Ligands for CD62L provide a mechanism for stem cell mobilization in conjunction with down-regulation of the CXCR4 chemokine receptor for stromal derived factor 1. Affinity immunoprecipitation was used to identify a novel ligand for CD62L from a water extract from AFA. The effects of AFA water extract on CD62L binding and CXCR4 expression was tested in vitro using human bone marrow CD34+ cells and the two progenitor cell lines, KG1a and K562. A double-blind randomized crossover study involving 12 healthy subjects evaluated the effects of consumption on stem cell mobilization in vivo.

Results
An AFA extract rich in the CD62L ligand reduced the fucoidan-mediated externalization of the CXCR4 chemokine receptor on bone marrow CD34+ cells by 30% and the CD62L+ CD34+ cell line KG1A by 50% but did not alter the CXCR4 expression levels on the CD34 cell line K562. A transient, 18% increase in numbers of circulating CD34+ stem cells maximized 1 hour after consumption (P<.0003). When 3 noncompliant volunteers were removed from analysis, the increase in CD34+ cells was 25% (P<.0001).

Conclusion
AFA water extract contains a novel ligand for CD62L. It modulates CXCR4 expression on CD34+ bone marrow cells in vitro and triggers the mobilization of CD34+ CD133+ and CD34+ CD133 cells in vivo.

Story of Christian Drapeau MSc. and StemEnhance

christian-drapeau2This is the story of how Christian Drapeau MSc. Chief Science Officer & Co-Founder of StemTech Health Sciences helped develop StemEnhance
A little over two decades ago, a new herbal supplement named Aphanizomenon flos-aquae (AFA), an aquatic botanical, made its appearance on the marketplace. Rapidly, AFA became popular for the wide variety of health benefits reported by consumers. Over the years we identified the presence in AFA of various bioactive compounds such as phycocyanin, a strong natural anti-inflammatory compound, a polysaccharide supporting immune function, and phenylethylamine (PEA), a molecule knows as “the molecule of love,” which increases mental clarity and provides a sense of well-being. Nevertheless, in spite of the identification of these various components, many health benefits reported by consumers remained unexplained.
At the turn of the 21st century, data began appearing in the scientific literature describing the potential of embryonic stem cells (ESC). Embryonic stem cells were shown to have the ability to become any kind of cells in the body. Soon after, studies revealed that adult stem cells (ASC) also had the ability of becoming virtually any kind of cells in the body. When this discovery was made, we hypothesized that adult stem cells constituted the natural renewal system of the body, and we published this hypothesis in the journal, Medical Hypotheses (October 2002). Our idea at the time was this: if adult stem cells indeed constituted the natural renewal system of the body, with adult stem cells being able to become any cell type of the body, then supporting this process could lead to a wide variety of health benefits. Given the broad spectrum of benefits reported by AFA consumers, we simply hypothesized that AFA was supporting aspects of stem cell physiology.
With this in mind, we initiated a series of laboratory experiments and soon discovered that consumption of large quantity of AFA (greater than 5 grams) increased the number of circulating stem cells by up to 30%. As we pursued our investigation to identify the compound in AFA responsible for this effect, we actually identified two specific compounds supporting both the release of stem cells from the bone marrow and their migration out of the blood into tissues. We then proceeded to concentrate these compounds out of AFA, achieving 5:1 concentrates for both compounds, and blended these compounds to make StemEnhance. One gram of StemEnhance supports the release of stem cells from the bone marrow and increases the number of stem cells from the bone marrow and increases the number of circulating stem cells by up to 30%. StemEnhance also concentrates phycocyanin and PEA, other important compounds found in AFA.
StemEnhance is a natural product made of 100% organic AFA and manufactured in accordance with GMP regulations. The powder is encapsulated and bottled in a pharmaceutical grade facility, providing the highest quality possible. Each lot of StemEnhance is tested for any potential contaminants, according to a stringent quality control program.
When asked why would one want to take StemEnhance, the answer is simply to support the body’s natural process of maintaining optimal health. Supporting stem cell physiology everyday by increasing the number of circulating stem cells is one of the wisest decisions one can make to regain and maintain optimal health.
