Does cytogenetic mosaicism in CD34+CD38low cells reflect the persistence of normal primitive hematopoietic progenitors in myeloid metaplasia with myelofibrosis?

Myeloid metaplasia with myelofibrosis (MMM) is a rare chronic myeloproliferative disorder characterized by myelofibrosis, extramedullary hematopoiesis, and absence of BCR-ABL rearrangement.[1][1],[2][2] Myeloproliferation is considered clonal and fibrosis, reactive.[2][2] Hierarchic level, primary
