干细胞研究离生育治疗还有多远
Producing sperm outside the body requires scientists to recreate a long sequence of biological signals. A recent experiment moved part of that process forward by turning human stem cells into immature sperm cells.
The cells were supported in an unusual living environment connected to a mouse kidney. That setting supplied conditions that a flat laboratory dish could not easily reproduce.
