[The] cells were subjected to half-media change every 7 days and their proliferation assessed on the same day by counting viable cells after trypan exclusion. To generate IL-3 dependent cell lines, successfully transduced bone marrow cells were cultured directly after sorting in DMEM, 15% FBS with mIL-3 alone (6ng/ml). A half-media change was done every 7 days.

3.6 Colony Forming Cells Assay (CFC-assay).

To check the differentiation and clonogenic potential of the BM cells expressing the various genes mentioned above, we performed a CFC assay by testing colony formation in methylcellulose. The CFC–assay was performed by culturing highly purified transduced cells (500 /dish) in 35mm-diameter Petri dishes directly after sorting in 1ml methylcellulose supplemented with cytokines (Methocult M3434), and incubated at 370C in humidified CO2 incubator. Colonies were counted microscopically on 7 to 9 days after plating according to standard criteria (Schwaller et. al., 1998). Re-plating capacity of clonogenic progenitors was assayed by re-plating the primary colonies on secondary methylcellulose dishes. Again colonies were counted day at 7 to 9 after the secondary re-plating.
