I think what you read about was tissue engineering, where you grow tissues outside the body using cell cultures in nutrient solutions. This is a bit different from what you are asking for; my guess is that there are treatments that may improve the lining of the veins, although I'm not knowledgeable to say anything about it.

OK, when it comes to memory I can give some authoritative answers: adrenaline does improve memory encoding when given in the right dose (above that, the effects become distracting). However, this is likely mostly useful for short-term effects. Some other stress hormones like ACTH also have positive memory effects, even if the corticosteroids (long term stress hormones) tends to impair memory. Outside these, estrogen has been shown to have positive effects on memory in women. Vassopressin *may* be useful, but I have not yet seen any clear studies showing its usability.
Most likely we can help ourselves a lot by tuning our hormonal systems, but it is often complex and tricky.
(However, I can attest that melatonin works wonderfully against jet-lag: it took one single dose after coming back from Extro to normalize my diurnal rhythm)
