Presence of primitive lymphoid progenitors with NK or B potential in ex vivo expanded bone marrow cell cultures

Objective. In previous work, we showed that CD34 + bone marrow cells can be successfully expanded along the myeloid pathway in stroma- and serum-free conditions in the presence of SCF+IL-3+IL-6+Flt3-l+G-CSF+MGDF. Due to the lack of phenotypically detectable lymphoid cells, it was necessary to addres...
