During preadiopcyte in vitro differentiation, cocktail stimuli is needed.
But why IBMX but not forskolin? Both of them can increase the intracellular level of cAMP and lead to PKA pathway activation? What's the difference
I've constructed several AAV vectors with TBG-promoter (which is liver specific) and FLAG-tag , while several of them cannot express in 293T cells (by Western Blot check with flag-tag antibody)....
