Researchers are studying the use of sperm cells as micromotors for delivering chemotherapy to cervical cancer patients.
One of the obvious problems with conventional chemotherapy is that it’s essentially poison formulated to kill cancer cells without killing the patient. While chemo is often the only available treatment option, it’s extremely rough on patients, causing debilitating exhaustion, weakness, and nausea. As a result, it can only be administered in limited doses. In addition, chemo can be diluted by body fluids and be broken down and weakened by enzymes. Now a team of scientists at Leibnitz Institute for Solid State and Materials Research are exploring a new way to aim cancer medications with greater precision directly at tumors while reducing side effects, thus making it safe to administer higher, more effective doses. That new way? Sperm cells.
Scientists conceptualize a potential avenue of creating an embryo with only male cells.
Remember that Arnold Schwarzenegger movie Junior where he was pregnant? Though it seemed hilarious and over-the-top at the time, scientists are actually close to making such a thing possible, sort of. Researchers at the University of Bath in the UK have opened up the possibility of an embryo using only male cells. Working with mice, they made a pseudo-embryo called a “parthenogenote.” This was an embryo created without sperm. The feat is performed by fooling an egg cell into thinking it’s been fertilized. Usually, a parthenogenote dies off after a few days. But here, scientists were able to fertilize them with a sperm cell, and inject each embryo into a female mouse.
Spanish scientists utilize a revolutionary new technique to create sperm from skin in a potential cure for infertility.
