Is anyone else using this? I'm curious how well SW+PGE2 alone works with microneedling.
Here's another patent for a first generation 15-PGDH inhibitor for hair growth. They tested it and found it grew hair even without exogenous PGE2, and this is less potent than SW033291. SW is too experimental for most, but the potential of this drug to promote hair growth is hard to match.
Surprisingly, the applicant has now demonstrated that an enzyme which is specifically involved in the degradation of these prostaglandins is present in the dermal papilla of the hair, which is a critical compartment for the life of the hair. Indeed, the applicant has now proved the presence of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) at this level. It has additionally shown that the specific inhibition of 15-PGDH has a beneficial effect on the hair density and/or growth.

"We have developed a drug that acts like a vitamin for tissue stem cells, stimulating their ability to repair tissues more quickly. The drug heals damage in multiple tissues, which suggests to us that it may have applications in treating many diseases."
these benefits emerged without any adverse side effects, even at SW033291 doses much higher than would be required for 15-PGDH inhibition.
SW033291 healed virtually all the ulcers in the animals' colons and prevented colitis symptoms. In mice where two-thirds of their livers had been removed surgically, SW033291 accelerated regrowth of new liver nearly twice as fast as normally happens without medication
Because bone marrow, colon, and liver are significantly different tissues, the investigators believe the pathway by which SW033291 speeds tissue regeneration is likely to work as well for treating diseases of many other tissues of the body.

It's been shown to have a strong effect on lung tissue as well in pulmonary fibrosis, and in kidneys. In every cell line it's tried it's been a miracle drug for stem cell proliferation. It's even suggested as a treatment for canities.

Dr Dusko Ilic of King's College London calls the results remarkable, but is cautious about the potential for tumor proliferation. They hope to use the drug to regenerate livers in liver cancer patients, but he dismisses the idea as too risky:
“
The drug seems to be too good to be true. The data presented show remarkable improvement in regeneration of multiple tissues. However, the study is performed only in mice and it would be encouraging to see a similar effect in other larger animal before even thinking about clinical trial in humans. What does worry me and curbs my enthusiasm is the fact that all the mouse disease models are actually otherwise healthy animals. For example, they show that after resection of two-thirds of the liver mass, mice treated with the experimental drug show increased rate of regeneration as compared with control.
When would one remove 2/3 of liver in human patients? The most often is in a case of malignant tumour. Giving drug to such patients would be too risky – if any tumour cell survived, it is likely that their proliferation would be potentiated. Thus, we may end up causing more harm to the patients. The drug might be more useful in patients who have had part of their liver removed after trauma-related injury, rather than from a tumour, but the same issue would still apply and we would have to be sure that nothing else was wrong with any organ in the body."
Prof. Alison at QMUL appears more optimistic:
“Although these studies were in mice, all three models are well validated, and with no adverse side-effects in the short-term. Obviously more experimental studies are needed before early clinical trials can start, but if successful, I see no reason why such an approach cannot be translated to the clinic quite quickly. The inhibitor may also have utility in other areas of significant human morbidity, for example, diabetic leg ulcers.”
