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.
Justru kami beralasan, ini harus menjadi faktor solusinya, jadi kami bisa mengambil saja bagian darah yang dapat larut yaitu plasma, dan menyuntikan baik plasma muda ataupun tua pada tikus ini, dan kita dapat menghasilkan efek peremajaan ini, tapi kita juga bisa menguji memori tikus.
