Abstract

A method of cultivating macrophages from blood, including collecting a quantity of blood, fractionating the quantity of blood into a plasma fraction, a white blood cell fraction generally including monocytes, and a red blood cell fraction, segregating the white blood cell fraction from the plasma fraction, while allowing a portion of the red blood cell fraction to remain mixed with the white blood cell fraction, the portion of the red blood cell fraction being less than the white blood cell fraction, and inducing differentiation of the monocytes into macrophages and lysing at least part of the portion of the red blood cell fraction mixed with the white blood cell fraction by causing an osmotic shock to the white blood cell fraction and the red blood cell fraction
