Morphology of nonadherent (a through c) and adherent (d through f ) populations derived from liquid culture. Cytocentrifuge preparations were stained with Wright-Giemsa. The fields of view shown are representative of the total cell populations. (a and d) Nonadherent and adherent parent MTHC cultured in murine GM-CSF; (b and e) nonadherent and adherent WTKit-expressing MTHC maintained in human SCF; (c and f ) nonadherent and adherent V816Kit-expressing MTHC maintained without factor. The bar in (a) is equivalent to 38 μm and all photographs are at the same magnification.
