General description
(Trimethylphosphoranylidene)acetonitrile is a reagent generally employed in the Wittig olefination of less reactive carboxylic acid compounds like esters, N-Boc lactams, lactones, and imides to give α,β-unsaturated nitriles. It is also used as an alternate reagent for Mitsonobu reaction by replacing DEAD/PPh3 for the alkylation of C-H and N-H bonds.
Other Notes
If precipitate is observed, warm gently to resolubilize

Stem cell therapy represents a promising strategy in regenerative medicine. However, cells need to be carefully preserved and processed before usage. In addition, cell transplantation carries immunogenicity and/or tumourigenicity risks. Mounting lines of evidence indicate that stem cells exert their
