To further enhance the BBB properties of the models, the medium was supplemented with cARLA (250 M 8-(4-chlorophenylthio)adenosine 3,5-cyclic monophosphate sodium salt, 17.5 M Ro-20-1724, 3 mM LiCl, 3 M A83-01
Its most significant and well-understood roles are: Collagen synthesis: Vitamin C is an essential co-factor for the enzymes prolyl hydroxylase and lysyl hydroxylase, which are required to stabilise the triple-helix structure of collagen fibres
In some embodiments, the use of an appropriate thermosetting polymer and an appropriate copolymer (e.g., a gelling agent) in combination with a specific pH range for the formulation allows for high temperature sterilization of formulations described with substantially no degradation of the therapeutic agent or the polymeric excipients
