Scientists Create Human Sperm from Stem Cells

Scientists Create Human Sperm from Stem Cells




Sperm Created from Stem Cells


Did you know that it took sixteen years for sperm to develop? Neither did I. That's what I learned in this remarkable article about sperm cells being developed by scientists from embryonic stem cells.
Could human life begin with them? Not yet but probably soon.

Genetically engineered neural stem cells approved for stroke trial

ReNeuron has just received permission to launch a clinical trial for stroke patients using neural stem cells. About a dozen patients will receive the cells at Southern General Hospital in Glasgow, Scotland. An article in the Financial Times chronicles the path to obtain regulatory permission to launch the trial in the UK. An article in NatureNews describes how the cells, derived originally from aborted fetuses, have been genetically engineered with an inducible gene to control cells’ growth. The prospect of transplanting genetically engineered cells worried advisors to the FDA’s panel on starting clinical trials with embryonic stem cells last year, though Geron is still pressing ahead on this front.
