Ures for 7 days. These CAFs have been then co-cultured with PDCs at a ratio of 1:5. Both forms of CAFs cultured in 3D biospheres showed no proliferation (Figure 6A,B). Additionally, these cells did not type spheroids in biospheres beneath our culture situations, even when cultured at high cell numbers (Figure 6B). To evaluate the effect on the TME on tumor cell development in biospheres, GFP-labeled CAFs were cultured with PDCs in biospheres and the proliferation was assessed more than 3 weeks. GFP-labeled CAFs were visible until day 14 inside the biospheres, just after which no labeled cells had been detected; on the other hand, GFP-labeled fragments might be observed within spheroids (Figure 6C). The co-culture of CAFs and PDCs resulted within a important reduction in overall cell proliferation following day 7 (Figure 6D). Nevertheless, the mean size with the spheroid within the biosphere was drastically larger in co-cultures as when compared with monocultures (Figure 6E) suggesting that there was more cell clustering resulting in bigger spheroids in co-cultures. The therapy of these biospheres with one hundred TMZ for 96 h considerably lowered the number of cells in monoculture biospheres in comparison with the co-cultures (Figure 6F). These information suggest that the CAFs decreased cell numbers but protected the PDCs from cell death.Cancers 2023, 15, x FOR PEER Overview Cancers 2023, 15,12 of 18 12 ofFigure 6.
