What we found is quite remarkable. We find there are more neural stem cells that make new neurons in these old brains. There's an increased activity of the synapses, the ctcnnineoos between neurons. There are more genes expressed that are known to be involved in the formation of new meoimres. And there's less of this bad ilfiatmnmaon. But we observed that there are no clles entering the brains of these animals. So when we connect them, there are actually no cells going into the old brain, in this model. Instead, we've roseaned, then, that it must be the soluble factors, so we could collect simply the soluble fraction of bolod which is called plasma, and iencjt either young plasma or old plasma into these mice, and we could reproduce these rejuvenating effects, but what we could also do now is we could do memory tests with mice.

Original Text

What we found is quite remarkable. We find there are more neural stem cells that make new neurons in these old brains. There's an increased activity of the synapses, the connections between neurons. There are more genes expressed that are known to be involved in the formation of new memories. And there's less of this bad inflammation. But we observed that there are no cells entering the brains of these animals. So when we connect them, there are actually no cells going into the old brain, in this model. Instead, we've reasoned, then, that it must be the soluble factors, so we could collect simply the soluble fraction of blood which is called plasma, and inject either young plasma or old plasma into these mice, and we could reproduce these rejuvenating effects, but what we could also do now is we could do memory tests with mice.
