Lab Assignments
Lab 1 Assignment:
1. The idea of In Vitro Fertilisation was influenced by the study of fertilisation of rabbit egg cells in test tubes. However as the cycle of human eggs is different to that of rabbits, further study and experimentation had to be done in order to achieve it. The first successful birth of an IVF baby occurred in 1978. Robert G. Edwards was awarded the Nobel Prize in 2010 for the development of In Vitro Fertilisation. [1]

Lab 2 Assignment:
An important protein associated with the process of implantation is Rac1. It is of the RhoGTPases family of proteins, and aids the embryonic trophoblast with invasion of the endometrium. Together with a protein known as RhoA, they are able to regulate cell migration and motility. It has been proven that motility is required in order for the trophoblast to invade the endometrium and for the embryo to be implanted within the uterine wall. Rac1 is needed as it promotes the trophoblast invasion. However, as this process must be tightly controlled, the protein RhoA is needed in order to restrict it. Therefore a balance between the two proteins must be achieved for successful implantation of the embryo in the endometrium.
