Periconceptional folic acid supplementation reduces the occurrence of several human congenital malformations, including craniofacial, heart and neural tube defects. Although the underlying mechanism is unknown, there may be a maternal-to-fetal folate-transport defect or an inherent fetal biochemical disorder that is neutralized by supplementation. Previous(More)
In mice, two pluripotent cell lines, embryonic stem (ES) cells and embryonic germ (EG) cells, have been identified. We present here results indicating that porcine EG cell lines can be isolated, genetically transformed, and utilized to make transgenic chimeras. Briefly, primordial germ cells (PGCs) were isolated from Day 25-27 fetuses and plated on STO(More)
The effect of cellular differentiation on fatty acid uptake and intracellular diffusion was examined in transfected pluripotent mouse embryonic stem (ES) cells stably expressing intestinal fatty acid binding protein (I-FABP). Control ES cells, whether differentiated or undifferentiated, did not express I-FABP. The initial rate and maximal uptake of the(More)
The development of new technologies that would increase the efficiency for generation of transgenic livestock and would overcome some of the problems associated with random insertion of the transgene will greatly benefit animal agriculture. A potential alternative technology to pronuclear injection for the generation of transgenic pigs involves the(More)
