In order to proceed with the chemo, they need to collect at least 2.5 million stem cells. The amount collected depends on general health, blood flow, etc. They collected a whopping 6.2 million today! That is a very good result. The kids said she should get an award for best stem cell collection.
The procedure is similar to dialysis, but for this, they pump the blood from the catheter tubes into a machine, which then uses a centrifuge to separate out the red, white, plasma, and stem cells due to different densities. They place the stem cell layer in its own bag, and treat it like gold. We are all born with a certain number of stem cells, and will never get new ones, so they are very precious. They come up with a special box on wheels, wrap the bag in layers of bubble wrap and blankets, and then transport it to the blood bank. The woman who had to do this was told that if she were to see a bus coming at her, she is to save the stem cells first. It was incredible how carefully they treat this bag. In the blood bank they will freeze it and then thaw a portion of it for the replant after the chemo. So a great day for collection.
