Hi Alyasa,
As the hematologists at NIH that treated Sally's husband said Neupogen should not increase blast cells in MDS patients. Here is a reference from my Professor (Hellström Lindberg) expert in MDS:
http://www.ncbi.nlm.nih.gov/pubmed/18559873
I have been taking 1 - 2 Neupogen injections during long periods without problems with the blast cells.
Kind regards
Birgitta-A
