I just came across this paper:
The inhibitory effect in vitro of salvia miltiorrhiza and tetramethyl pyrazine on the growth of fibroblasts

I don’t think we want growth inhibition of fibroblasts. there are some more papers about this topic.

need another tgf-ß inhibitor without adverse effects, do you have a suggestion with proof?
