This pattern of light absorption can be used to isolate specific cell associations during sperm cell differentiation ... of degenerating cells. Problem: The cells keep moving under the microscope.

More than a decade ago, scientists succeeded for the first time in generating primordial germ cells—the precursors of sperm and eggs—from embryonic stem cells, a process that led to functional sperm ...

All new babies start as an egg and a sperm, but where do those two cells come from in the first place? Your reproductive organs produce the sex cells that make a baby. Sperm cells begin their life ...
