Embryonic Stem Cell Research

Embryonic stem cells, the initial construction blocks of life, are the body's founder cells. An ovum and a sperm fertilize to pattern a zygote, which serially splits up to evolve into a ball of roughly attached units, called a morula, by the fourth day of development. Embryonic arise units are drawn from from the inward cell mass round day four or day five postfertilization. After isolation, the embryonic arise units are civilised in the laboratory.
