The trial involves grafting hMSCs intopatients suffering from interveterbral disc disease using a degradable polymer scaffold. You are going to 3Dprint a porous cylindrical scaffold that is 2 cm in radius and 1 cm in height (matching the dimensions of adegenerated disc). Assume a porosity of 50%. You will fill available volume of the scaffold with hMSCs at adensity of 1 million cells per cm3. Based on the data above, what starting number of cells will you use andhow long will it take you to get enough cells for the trial? Part2The trial is a failure (patients did not report any reduction in back pain). Your team wants to try againusing 85% hMSCs and 15% nucleus pulposus cells .…You are given a cell stock A. You make a 1:100 dilution and load 10uL diluted sample to a hemocytometer. After counting all 5 "one millimeter squares" you have 51 cells in average. (Please write down each step)T 1. What is the cell concentration of this diluted sample? 2. What is the cell concentration of original cell stock ? 3. If the original stock A has a total volume of 5mL, what is total number of cells in the A? 4. You decide to do a 1:1000 dilution to verify your counting. After loading and counting, you find out that you have 20 cells in average in each square. Do you think the new concentration is consistent with your previous result? If not, list all the possible errors that can cause this inconsistency.
