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.
The word cell was first used by English scientist Robert Hooke in 1665 to describe the cell walls visible in cork when seen through a microscope. In 1838 the German botanist Mâ¦atthias Schleiden concluded that all plant tissues were made of cells. In 1839 the zoologist Theodor Schwann reached the same conclusion about animal tissues. By 1885 the German physiologist concluded that cells only originated by the division of a preexisting cell.
