摘要

PROBLEM TO BE SOLVED: To provide a system and a method capable of recovering stem cells at a high percentage and red blood cells at a low percentage.SOLUTION: The stem cell compositions includes compositions of stem and progenitor cells recovered from bone marrow or cord blood containing most of the viable CD34+ cells and substantially depleted of red blood cells resident in the original sample, without any xenobiotic additives to aid cell separation. The system for preparing the compositions includes a bag set 100 and a processing device, which utilizes an optical sensor, microcontroller, servo motor, accelerometer, load cell, and battery. The system and method utilize centrifugation to stratify the cells into layers and then separate and transfer the stem cells into a stem cell bag 106. The processing device's microcontroller receives input from the device's accelerometer, load cell and optical sensor to direct the metering valve 138 in the bag set to open and close to permit the transfer of as many stems cells as possible with as few red cells as possible.
