Cell division with no significant growth, producing a cluster of cells that is the same size as the original zygote, is called cleavage. At least four initial cell divisions occur, resulting in a dense ball of at least sixteen cells called the morula. In the early mouse embryo, the sister cells of each division remain connected during ...
About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium. All 11 are necessary for life.
Cells differentiate into an outer layer of cells called the trophoblast, and an inner cell mass. With further compaction the individual outer blastomeres, the trophoblasts, become indistinguishable. They are still enclosed within the zona pellucida. This compaction serves to make the structure watertight, containing the fluid that the cells ...

No bigger than the head of a sharpened pencil, “biobots” fill the therapeutic niche between nanotechnology and traditional medical devices.
The vaccines do not contain any of the original fetal tissue or cells or cells derived from fetal materials. [5] Although the vaccine materials are purified from cell debris, traces of human DNA fragments remain. [6] [7] [8] The cell lines continue to replicate on their own and no further sources of fetal cells are needed. [5]

"Stem cells have this fancy term," Dr. Schmidt, a microbiology professor at Medical University of South Carolina, told WCIV. "They are called pluripotent which is code for they just make more.
