Hi
I'm having problem for culturing hcmec/D3 cell. I tried with collagen or gelatin. In gelatin the cells are dividing but not differentiating. Any advice in the usage of collagen. I´m using collagen from merck millipore, dilution 1/20 in PBS 1X.
I am tring to culture cells in hypoxia using Cobalt chloride model , but I want to compare with antoher method. Our research is about circRNA expression - qPCR and nanopore oxford sequencing.
