the alternative is to work with human cells in vitro in test tubes. the cells here form tiny versions of organs such as miniature brains. in vitro methods are especially useful for answering specific questions such as which substances damage which cells in the brain. may be some time until an more testing is abandoned how are. worldwide an estimated four hundred thousand. robert c. year i used to love experiments despite an alternative method developed by thomas hartnell. in rabbit pirate in tests medicines vaccines or blood products are injected into the animal's ears and their body temperature is measured. this reveals whether the samples are contaminated with pirates substances the course fever. part of his method replaces the rabbits with human blood. or discoloration of the liquid indicates a contamination in the sample. the test took fifteen years of development until it was authorised and even now it is barely being used. we have to remember the different conditions in different geographical and political regions. imagine a globally operating c

after the uterine transplant eggs taken from the woman's ovary are fertilized in vitro. the embryo is then transferred to the new transplanted womb. things is this is the vagina. the uterus out. as with other organ transplants the patient is given immune suppressants to prevent rejection so far there's been little research on possible long term effect on mother and child so her book or presented the results of her first transplant at the gynecology congress in stuttgart. the procedure is controversial because it's not a life saving measure like say a liver or heart transplant and many view it more as a personal choice. they are what tied him down who decides which woman gets to have the child she wants and which doesn't but doctor does there are pros and cons when it comes to uterine transplant and we need to have an open discussion about the issue in germany. so far that debate hasn't taken place the german ethics council has yet to officially address the issue. professor. is a member of the council she specializes in the ethical aspects of reproductive medicine and its

which are 3d cellular structures replicating normal organ function in vitro for brain, liver, pancreas, against intestines, stomach, lung, kidney and eye. these organiod ises have proven successful in zika virus, micro encephalopathy, and infectious disease and cancer and many others. postmortem donations are another useful solution. one option is stem cells isolated up to several days after death. finally, we do not need fresh fetal tissue from humanized mice because alternatives are available and being used now. surplus human thymus tissue from newborn babies obtained during surgical procedures as well as cd-34 positive hematocritic stem cells from cord blood, adult bone marrow and gsf-mobilized peripheral blood are all successful alternatives. in fact, human core blood is perhaps the best scientific and noncontroversial source for optimal human cell engraftment. because it is abundant. and more efficient and clinically relevant with respect to immune response. other options, other options include the ability of researchers to actually purchase humanized mice directly from commercial

prentice that talked about the fact that if you have someone doing cardiac surgery on either in vitro or not that there is discarded tissue that would have the same properties. do you agree that they would have the same properties as an aborted fetus? >> not at all. >> why would they not have the same properties for research. >> let me clarify for research. >> you are saying scientifically they do not have so we can abort a fetus and we can take that same gland and they would not have and it's the same material and they wouldn't have the same property. >> it is not the same material. it is a different developmental state and it has a unique property. >> so what developmental stage are you recommending that we -- because i know that you've been purchasing. so what developmental stage do you purchase fetal tissue? from abr, what are you purchasing from them? >> so for the blt mack, we do not generate that, but i think we can provide the information -- >> earlier when mr. jordan asked a question, you said that you bought fetal tissue from abr. >> yes. >> at what period of gestation are t
