...lls into the mice was narrow, and the mouse liver, despite efforts to make the animal immunodeficient, often rejected the human cells. Grompe's laboratory now has a system in which those disadvantages have been engineered out.

... number is growing. The increased use has occurred despite the fact that the cardiovascular effects of chronic testosterone treatment in aging males are largely unknown, and the safety of testosterone replacement has not been evaluated.

The new research opens up a new avenue of treatment in glaucoma which does not involve treating intraocular pressure.

These mice began behaving like males, despite the fact that they -- like mutant females in the study -- showed testosterone levels, estrogen levels, and estrus cycles indistinguishable from those found in normal females. "It had previously been thought that entirely different neural circuits, ...Strains of laboratory mice more varied than previously thought
...The researchers concluded that the NIEHS data set, despite its exceptional size, density and qualitycaptures only a fraction of the variation present in the laboratory mouse.
