Although some insights have been gained from previous studies on the acceptability of genetically modified (GM) foods, not many attempts have been made to understand consumer acceptability of genetically modified tomatoes. The purpose of this study is to understand the impact of factors such as consumer knowledge, beliefs, and attitudes on the acceptability of genetically modified tomatoes. The analysis draws on data from a consumer survey conducted at several grocery stores in Alabama in 2003. The results revealed a diversified set of preferences toward GM tomatoes. Logit results suggest that attitude toward the use of genetic modification technology in food production, opinion about labeling, and consumer perceptions about the safety of GM foods strongly influence consumers' decisions. The utility advantage of purchasing non-GM tomatoes corresponds to an average premium of $0.39 per pound, implying that consumers would be willing to purchase non-GM tomatoes at a price $0.39 higher than the price of GM tomatoes.

Background/Aim: Recent interest in the liver stem cell field has led to the identification and characterization of several hepatic progenitor cell populations from fetal and adult tissues. We isolated a hepatic progenitor cell from naïve adult liver and the current studies focus on differentiation and growth.

In this study we have isolated and identified a progenitor cell population located in murine pancreatic tissue. This cell population has specific properties that make it different from previously described candidate pancreatic progenytor cell populations. It is located in the periductal region outside the islet architecture yet the cells have features consistent with endodermal development and endocrine functions within the islet. Cells are proliferative and capable of differentiation into pancreatic lineages expressing pancreatic associated transcription factors and proteins and maintaining the ability to produce insulin
