How long does it take for blood count to increase after stem cell transplant
Engraftment and recovery. About 10 to 20 days following your transplant, we can begin to see signs that your stem cells are growing (engrafting) and beginning to produce blood cells. During this time, you may notice aching in your bones, especially your pelvis, lower back and thighs.his is because you have fewer red blood cells to carry oxygen to the organs in your body. We will give you a transfusion of red blood cells if your count drops to a certain level. Keep in mind that this profound fatigue is common among transplant patients.
