associate director of bio-manufacturing, delasie dela-seshie, is going to show me how they make this cutting edge science a reality. - [delasie] hair net first, face mask, a couple pairs of gloves, lab, coat, and shoe covers. - [julia] and why do we have to wear all of this here? - [delasie] it's purely to make sure that as humans, we're not contaminating the product that's going into an already compromised patient. - [julia] i mean, i'm looking fantastic, so. - [delasie] great. - [julia] feeling great, looking great. i'm ready to go. - [delasie] perfect, awesome. this is essentially the first step. this is where they'll do a visual assessment of the sample. - [julia] and what are the assessment criteria for a piece of poo? like what is a good piece? - [delasie] so there's a visual assessment for color. it's also assessed for size. there's also a scale that we grade the stool on. it's gonna give you viscosity, texture, hardness. - [julia] i never thought i'd say i'm looking forward to seeing a piece of poo. - [delasie] yeah, yeah. - [julia] but here we go, i'm excited. - [delasie] so
