Sperm Cells to Help in the Treat­ment of Can­cer

Ar­moured sperm cells will carry can­cer-killing chemo drugs to tu­mours in women’s ab­domens.

In Ger­many, sci­en­tists have de­vel­oped a sen­sa­tional new weapon in the strug­gle against can­cer in women’s ab­domens. They aim to use sperm cells to carry chemo drugs to can­cer cells in the womb, cervix, etc.

Sci­en­tists from the Uni­ver­sity of Chem­nitz, etc., first soaked the sperm cells in the chemo drugs, which en­tered into the cells. Sub­se­quently, they used a beam of elec­trons to cut out mi­cro­scopic "suits" for the sperm cells, lin­ing the suits with iron and ti­ta­nium. The sperm cells swam into their cus­tom­ized ar­mour them­selves and could sub­se­quently be steered about a cul­ture dish by means of a mag­net.

The next step con­sisted in plac­ing lumps of can­cer cells in the cul­ture dish. When the sperm cells were steered into a can­cer lump,

the ar­mour fell off, and the tiny cells could en­ter the lump, where they man­aged to re­lease their load of drugs, killing can­cer cells.
