Introduction For centuries scientists have tried to develop a new way of creating life or of helping fertilization Cloning IVF ACT
Cloning • ´´Cloning is the creation of an organism that is an exact genetic copy of another. This means that every single bit of DNA is the same between the two!´´ There are different types of cloning • TherapeuticCloning • ReproductiveCloning DNA Cloning
ReproductiveCloning • Mostknowntype • There are severalmethodsamongwhich are: • Artificial embryotwinning • Somaticcell nuclear transfer
Artificial embryo twinning • Mimics a natural process • Twins occur when a zygote divides into two celled embryo. • Both cells start developing on their own • Artificial process is performed in a lab. Within a Petri dish • Manual separation of the Zygote
Somatic nuclear transfer • This process starts isolating a somatic cell from an adult female. • The nucleus is taken out of the somatic cell • The nucleus is inserted into an egg without nucleus. • Some chemicals are injected in the egg. • Starts behaving as a zygote.
ACT • Artificial cell technology • Developed in the J. Craig Venterinstitute • Over 15 years of research • A cell structurefilledwithcomputermadegenetic material • Notonlysome genes, but a full genome
In Vitro Fertilization • The in vitro fertilization is a process where the egg is fertilized out side of the body. • It works removing the egg from ovaries and letting the sperm fertilize it in a laboratory • The zygote is then introduced into the uterus of the carrier • Some of the in vitro fertilization examples are: • Zygote intrafallopian transfer • Intracytoplasmic sperm injection
Intracytoplasmic sperm injection • Treatsmaleinfertilityproblems, oregghyperresistance • It is usedtoguetherwithanothermethodthat is Oocyte (ImmatureOvum) extraction • Usingmicrotools and a microscope, thesperm`stail is cutted and it is insertedintotheoocyte. • Theeggbecomesfertilized and it is insertedinsidethemother.
Zygoteintrafallopian transfer (ZIFT) • Usedwhendueto a defect, the sperm is unabletomeettheegg. • Theprocesstakesabout 5 weeksto complete • Femalemusttake a fertilitymedication • Whenthefollicles are mature HCG isinjected
Zygoteintrafallopian transfer (ZIFT) • 36 hourslatertheeggs are removed bytransvaginalovumretrieval • Theeggisfertilized in thelaboratory • Placed againinsidethewomanthroulaparoscope
