The royal jelly had no effect on the leukemia cells, but it had dramatic effects on sarcoma cells. Royal jelly, however, has not lived up to expectations that it is an important anti-aging substance. But it is not without medical interest. Royal jelly consists of an emulsion of proteins, sugars, lipids and some other substances in a water base. Proteins make up about 13% of royal jelly. Most of the proteins comprise a family called major royal jelly proteins.
Cells were first discovered by Robert Hooke in 1663.
This led to the knowledge that all living things were made of cells. In 1855, German physician Rudolph Virchow theorized that all living cells come from other living cells. The contributions of these people led to what we now refer to as the cell theory. This theory states: 1. All living things are made of one or more cells. 2. The cell is the smallest unit of a living organism. 3. Cells come from other cells.
