Rapid and selective mobilization of specific stem cell types after consumption of a polyphenol-rich extract from sea buckthorn berries () in healthy human subjects.

Purpose: The aim of this study was to evaluate the effects of a proanthocyanidin-rich extract of sea buckthorn berry (SBB-PE) on the numbers of various types of adult stem cells in the blood circulation of healthy human subjects.

Study Design And Methods: A randomized, double-blind, placebo-controlled, cross-over trial was conducted in 12 healthy subjects. Blood samples were taken immediately before and at 1 and 2 hours after consuming either placebo or 500 mg SBB-PE.

Mobilization of bone marrow stem cells with StemEnhance improves muscle regeneration in cardiotoxin-induced muscle injury.

Bone marrow-derived stem cells have the ability to migrate to sites of tissue damage and participate in tissue regeneration. The number of circulating stem cells has been shown to be a key parameter in this process. Therefore, stimulating the mobilization of bone marrow stem cells may accelerate tissue regeneration in various animal models of injury.

The stem cell mobilizer StemEnhance does not promote tumor growth in an orthotopic model of human breast cancer.

Bone marrow-derived stem cells (BMDSC) have been implicated in tumor formation, though it is not clear whether they contribute to tumor growth. A novel mobilizer of BMDSC (StemEnhance; SE) was used to investigate whether its daily administration promotes tumor growth. Forty mice were surgically transplanted with human MDA-MB-435-GFP breast cancer into the mammary fat pad of nude mice, The mice were gavaged for six weeks with 300 mg/kg of SE.

Natural killer cell activation and modulation of chemokine receptor profile in vitro by an extract from the cyanophyta Aphanizomenon flos-aquae.

The present research was designed to study the effects of an extract from the edible cyanophyta Aphanizomenon flos-aquae on human natural killer (NK) cells. We have previously shown, using a double-blind randomized placebo-controlled crossover design, that ingestion of 1.5 g of dried whole A.

Mobilization of human CD34+ CD133+ and CD34+ CD133(-) stem cells in vivo by consumption of an extract from Aphanizomenon flos-aquae--related to modulation of CXCR4 expression by an L-selectin ligand?

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.

Pancreatic and intestinal enzyme activities in rats in response to balanced and unbalanced plant diets.

To simulate the effects of nutritionally adequate and inadequate vegetarian diets, rats were fed, for 28 days, an isonitrogenous, isocaloric, amino acid unbalanced cereal diet (CD) deficient in lysine and tryptophan or a balanced cereal-legume diet (CLD). The impact of these diets on enzymes responsible for digestion of proteins and carbohydrates were measured. Neither experimental diet significantly affected the animal's final weight or feed consumption in comparison with controls fed a standard mixed diet from plant and animal sources.

The use of in situ bone marrow stem cells for the treatment of various degenerative diseases.

The potential for tissue repair and regeneration is encouraging in the light of novel research on the plasticity of adult stem cells. Intense research efforts over the last 3 years have provided solid evidence for the continuous generation of many types of tissue cells from adult stem cells as a normal part of our physiology throughout development and adult life in mammals, including humans. This opens new therapeutic avenues for many clinical problems and provides alternative opportunities at a time when much attention has been brought to the issue of using embryonic stem cells for research purposes and for the development of treatments for various diseases.
