Answer
(Fatwa: 72/72=M)
According to Islam, pig is impure and each part of it is haram and impure. Its impurity has been implicitly mentioned in the Quran. So, before giving any ruling about the method of scientific research, we would like to know from you whether this research can be done on pigs or on any other animal i.e. whether there is an alternative animal or not. Secondly, whether getting the medical purpose from the research is sure or uncertain. Thirdly, whether your friend who is entrusted this work is bound to do it or he has some options. Please, ask the question again explaining all these points.
