Numb-deficient satellite cells have a proliferation deficit. (A) The loss of Numb resulted in a static cell number. Satellite cells were plated in growth medium after treatment with 4OH-T or ethanol; genotypes are as indicated. Triplicate wells were trypsinized daily, stained with 0.4% Trypan Blue, and counted. Data are mean number of cells ± SD (n = 3). (B) Caspase 3/7activity showed that Numb-deficient satellite cells had no increase in apoptosis in culture. ER-Nbfl/fl Nblfl/fl and Nbfl/fl Nblfl/fl satellite cells after 4OH-T or ethanol treatment; data are mean Luciferase levels ± SD (n = 4).
