In one surprising result, researchers showed that brain cells from adult mice can, when injected into early mouse embryos, become cells in the heart, stomach, liver, and other organs of a developing fetus.
For example, nuclei of brain cells from whole mice stored at −20 °C (−4 °F) for more than 15 years have been used to generate lines of embryonic stem cells.
To test that idea, they first cultured brain cells from embryonic mice, added a standardized ginkgo biloba extract, and tested to see how well the lab-grown neurons survived oxidative stress.
Our study is further in line with recent findings studying the effect of GBE after in vivo treatment on mitochondrial membrane potential in dissociated brain cells from aged mice after inhibiting OXPHOS using specific inhibitors of complexes [11].
3C was performed using fetal liver and brain cells from E18.5 mice; in the latter the Hbb-b1 gene is silent and the β-globin locus is in an extended conformation, whereas in the former the active gene and LCR interact to form a higher-order chromatin structure [11], [13].
Brain cells from sleep-deprived mice also held about 50% less cAMP than did cells from well-rested mice.
There was no comparable activity in brain cells from the sedentary mice.
Essentially they found that if you give a load of cocaine (known among the street youths as "toot" or "naughty sherbet") to mice, this out-of-control brain process happens that leads to cell death, but an experimental and human-tested drug called CGP3466B can protect the mice brain cells from the ol' eating themselves to death thing.
In the new study, Tanzi said his team showed that the herpes viruses could "rapidly" induce amyloid plaque production in mice (within 24 to 48 hours); that the plaques are trapping the virus to protect the brain cells from viral infection; and that the mice bred with the ability to create amyloid beta were better able to fight brain infection than the mice without it.
We isolated mouse embryonic fibroblast (MEF) cells and embryonic brain cells from wild-type (WT) and Bbs mutant mice (Bbs1 M390R/M390R knockin, Bbs2 −/−, Bbs4 −/− and Bbs7 −/−).
