... KEY CONCEPT The human body has five levels of organization. Humans, like all multicellular organisms, are made up of specialized cells that work together. These cells arise from a single cell, the zygote, which divides to form embryonic stem cells. Stem cells can become any one of more than 200 diff ...

Artificial insemination
... • Artificial insemination is when sperm is placed into a female's uterus or cervix using artificial means rather than by natural copulation. • Either the woman's husband's sperm or a known or an anonymous sperm donor can be used. • Eugenics means the application of reproductive medicine not to help ...

Embryonic stem cell
Embryonic stem cells (ES cells) are pluripotent stem cells derived from the inner cell mass of a blastocyst, an early-stage preimplantation embryo. Human embryos reach the blastocyst stage 4–5 days post fertilization, at which time they consist of 50–150 cells. Isolating the embryoblast or inner cell mass (ICM) results in destruction of the blastocyst, which raises ethical issues, including whether or not embryos at the pre-implantation stage should be considered to have the same moral or legal status as more developed human beings.Human ES cells measure approximately 14 μm while mouse ES cells are closer to 8 μm.
