Enhanced growth was observed in the experimental group. Caveolin 3 was seen in fraction 5 of human, transgenic, and nontransgenic pig heart, consistent with other reports studying human tissues 19 , The latter was probably due to the greater amount of DNA injected. Expression was stable and found in caveolae as it is in human cells. For xenotransplantation purposes, five to seven other pig genes will also need to be silenced or replaced by other human genes. In order to find out whether the transgene could be transmitted to the next generation, ten founder pigs expressing different levels of hDAF mRNA were mated and produced piglets in 20 litters.
Sperm-Mediated Gene Transfer: Concepts and Controversies
Development of a mass gene transfer method in chinook salmon: Sperm cells were incubated in a buffer containing lacZ or cat genes and then used to inseminate hens. In addition to the generation of transgenic mice, the use of SMGT technologies has resulted in multiple insights into male reproductive biology. From genes to organism , Singapore: Science , —3. The researchers found that the method would only work if fresh sperm was used.
Research on Key Factors Restricting Efficiency of Sperm-Mediated Gene Transfer
AgBiotechNet Information on agricultural biotechnology for plant and animal researchers and policy-makers. Electroporation of salmon sperm for gene transfer: Genetic transformation of chickens using irradiated male gametes , Heridity , 58 , What's new in Forthcoming Titles in Forthcoming Series. Although mature sperm cells are naturally protected against uptake of foreign nucleic acid molecules, certain environmental conditions, for example at key times within the reproductive tract, may reduce this protection, suggesting that SMGT may occasionally take place in nature. Many studies have shown that the transferred DNA remains extra chromosomal and a few have observed that they have been rearranged or modified.

Although not yet perfect, the technique of SMGT is of high biotechnological and medical potential. All of the controls gave negative results. As a result, the web page can not be displayed.
