Figure 1From: Enhanced self-renewal of hematopoietic stem/progenitor cells mediated by the stem cell gene Sall4Over-expression of Sall4 isoforms enhanced and supported LSK cell growth in culture. (a) Viable cell numbers were counted for each group of LSK cells at different days (N = 4). Error bars represent standard error of the mean. (b) Morphology observation of GFP control or Sall4 isoforms transduced LSK cells under microscope inspection at different days. GFP transduced LSK cells grew relatively slower than Sall4 treated LSK cells and died after 4 weeks of culture, while the latter continued to proliferate in dishes.Back to article page
