Abstract: The present invention claims and discloses a novel apparatus and method for efficiently cultivating cells with minimal mortality in order to harvest a maximum amount of cellular products generated by the cultivated cells. More particularly, the present invention teaches a method and a device for plating cells and causing maximum adherence of cells of interest. Furthermore, the present invention also teaches a growth substrate means that is capable of providing the largest surface area for cell adhesion and functions as an oxygenator, a depth filter and a static mixer to maximize the production of cellular products by intermittently and periodically provide sufficient oxygen and nutrients to the cells without causing cell death.
