Figure 4. Mang-NPs inhibit cell viability in spheroids formed by Pan CSCs isolated from human and KrasG12D mice.
(A) Human pancreatic CSCs were treated with Mang-NPs (0–10 μM) for 7 days to obtain primary spheroids. At the end of incubation period, spheroids were collected, reseeded and treated with Mang-NPs for another week to obtain secondary spheroids. Secondary spheroids were collected, reseeded and treated with Mang-NPs for another week to obtain tertiary spheroids. Cell viability in spheroids was measured by trypan blue assay at the end of 7, 14 and 21 days. Data represent mean ± SD. *, & and # = significantly different from control, P < 0.05. (B) Mouse pancreatic CSCs were treated with Mang-NPs (0–10 μM) for 7 days to obtain primary spheroids. At the end of incubation period, spheroids were collected, reseeded and treated with Mang-NPs for another week to obtain secondary spheroids. Secondary spheroids were collected, reseeded and treated with Mang-NPs for another week to obtain tertiary spheroids.
