First. The Ichims are still obviously involved as they turned over their intellectual property ownership to RGBP on much of their research. TIchim is still a senior advisor.
Second, their SAB has been created to replace house scientists. They are a virtual biotech. Little or no owned lab space, few if any Inhouse scientists, owner of cutting edge intellectual property that is studied and moved forward in third party research facilities in many cases by SAB members. Lander along with T Ichim's guidance has the chops to oversee the progress. It's akin to an airbandb or uber model. Nothing owned, other's assets are leveraged. Great model.
