    Abstract: PURPOSE: A GFP(Green Fluorescent Protein)-transfected clone pig, a GT(alpha 1, 3 galactrosyltransferase) knock-out clone pig and a production method thereof are provided to produce a clone pig with a determined genetic character using transfection and targeting technologies. CONSTITUTION: The production method of the GFP-transfected clone pig comprises the steps of: preparing a cell line taken and cultured from a pig as a nucleus donating cell; introducing the GFP clone to the nucleus donating cell and expressing by forming a lipid(or a positive charge polymer)-DNA structure complex, adding the complex to the nucleus donating cell culture solution and culturing; producing a transfected embryo by transplanting the cell to an enucleated pig embryo and activating; and producing a piglet by transplanting the embryo to a surrogate mother.

    Abstract: A mesonephric stem cell line is provided to be differentiated into various cells, treat various diseases or disorders through cell therapy and be used for developing a transgenic animal used for xenotransplantation. A method for preparing a mesonephric stem cell line comprises the steps of: (a) obtaining a mesonephric stem cell from mesonephros of mammal; (b) culturing the mesonephric stem cell onto a feeder cell layer to form a colony; and (c) subculturing the colony to obtain the mesonephric stem cell line, wherein the mammal is human, pig, cattle, sheep, horse, rabbit, goat, mouse, hamster or rat and the feeder cell layer is a fibroblast layer. A mesonephric stem cell line is derived from the mesonephros of the mammal and is characterized in that it show a positive reaction regarding alkaline phosphatase and has the ability of being naturally differentiated into embryonic bodies. Further, the fibroblast is derived from ICR mouse, and a number of the fibroblast is 1.8 to 2.8x10^5 cell/ml.

    Abstract: PURPOSE: A method of in vitro fertilization showing reduced polyspermy and tubes therefor are provided to reduce polyspermy while deducing a sperm penetration in a high proportion. CONSTITUTION: The method of in vitro fertilization showing reduced polyspermy comprises the steps of: disposing an ovum containing sample at the top of a tube with a sperm containing sample at the bottom; and fertilizing the ovum for a motile sperm so as to swim-up from the sperm containing sample to a location where the ovum containing sample is. The ovum and sperm are obtained from a mammal such as a pig, a cow, a sheep, a goat, a mouse, a white rat, a rabbit and a human.
